Carbon Black Production From Waste Tire Pyrolysis

keke — Tue, 01 Sep 2026 11:16:34 +0100

Waste tires contain approximately 30% reinforcing carbon black, a key filler that provides wear resistance and anti-aging properties. Pyrolysis equipment enables the carbon black production from these tires, while also yielding pyrolysis oil, steel wire, and combustible syngas.

The tyre pyrolysis plant https://www.pyrolysismachine.com/tyre-pyrolysis-plant/ thermally decomposes waste tires in an oxygen-free, sealed environment to produce raw pyrolysis carbon black. This material is then subjected to purification, modification, and granulation to yield recovered carbon black.

During the pyrolysis process, waste tires are converted into three product phases: pyrolysis oil, pyrolysis gas, and solid carbon black. Solid carbon black accounts for approximately 30%–35% of the output.

Waste Tyre Pyrolysis Carbon Black
However, the crude carbon black obtained directly from pyrolysis is of low quality, characterized by high ash content, poor activity, and large particle size. Consequently, it must undergo systematic deep processing to be upgraded into recoverable carbon black.

The following section outlines the carbon black production process from waste tires, covering the entire value chain from pretreatment, pyrolysis to deep processing.

Carbon Black Production Process
Waste Tire Pre-treatment
Waste tires are cut into 5–10 cm rubber granules using a shredder. Simultaneously, the majority of the steel wire is removed via magnetic separation. The size of the shredded rubber pieces directly affects the efficiency of the subsequent pyrolysis process; smaller granules ensure more uniform heating and a more complete pyrolysis reaction.

Sealed Feeding
The rubber granules are fed into the fully automatic pyrolysis plant https://www.pyrolysismachine.com/fully-continuous-pyrolysis-plant/ via a sealed screw feeder. The entire conveying process operates under negative pressure within a sealed system, preventing dust leakage and protecting the carbon black feedstock from premature oxidation or degradation.

Waste Tire Pyrolysis Equipment
Tire Pyrolysis
The rubber granules enter the pyrolysis machine, where they are heated to 500–600°C in the absence of air, causing the long-chain rubber polymers to break down. The oil and gas components form high-temperature pyrolysis vapors, which enter a condensation system for oil recovery. The solid residue—a mixture of carbon black and steel wire—is continuously discharged from the rear of the reactor. Combustible syngas generated during pyrolysis is recovered and burned to provide heat for the reactor, achieving energy self-sufficiency.

The exhaust gas generated during the waste tires pyrolysis undergoes a multi-stage purification system to ensure emissions meet regulatory standards.

Separation and Purification of Crude Carbon Black
The mixture of carbon black and steel wire discharged from the furnace bottom enters high-intensity magnetic separation equipment, where high-purity tire steel wire is completely separated. The resulting crude carbon black contains trace amounts of rubber ash and inorganic fillers. It undergoes multi-stage vibrating screening and air-swept dedusting to remove large-particle impurities, yielding a primary crude carbon black powder.

Carbon Black
Refined Modification of Recovered Carbon Black
The crude carbon black is fed into an ultrafine pulverizer to reduce particle size, thereby enhancing tinting strength and reinforcing properties. It is then introduced into an activation reactor and subjected to high-temperature activation using trace amounts of water vapor or carbon dioxide. This process opens the carbon black’s closed pores, improving adsorption performance. Simultaneously, desulfurization and de-ashing occur, reducing sulfur and ash content to meet raw material standards for the rubber industry.

Carbon Black Granulation
The modified ultrafine carbon black powder is prone to dusting and high transport losses. Wet or dry granulation processes are employed to produce high-strength carbon black granules, facilitating packaging and transportation.

Summary
The recovered carbon black production https://www.pyrolysismachine.com/carbon-black-production/ from waste tires via pyrolysis establishes a circular pathway transforming waste rubber into high-end carbon materials. This approach not only addresses the challenge of managing “black pollution” caused by waste tires but also reduces the extraction of fossil-based raw materials and lowers industrial carbon emissions.

In terms of environmental benefits, pyrolyzing one ton of waste tires reduces carbon dioxide emissions by approximately 1.1 tons. Based on an annual processing capacity of 100,000 tons, this translates to an annual reduction of over 110,000 tons of CO2 emissions. With continuous upgrades to pyrolysis equipment and ongoing breakthroughs in deep-processing technologies for carbon black, the industry for producing carbon black from waste tires is poised for significant growth.

Tyre Recycling Pyrolysis Technology for Handling Waste Tires

keke — Tue, 01 Sep 2026 10:50:15 +0100

Pyrolysis technology holds the key to solving the challenge of tire pollution. Among the various methods for handling waste tires, tyre recycling pyrolysis is widely recognized as one of the most effective disposal solutions.

Mingjie Tyre Pyrolysis Plant https://www.pyrolysismachine.com/tyre-pyrolysis-plant/ utilizes this technology to convert waste tires into valuable products: pyrolysis oil, combustible gas, solid carbon black, and steel wire.

Tyre Recycling Pyrolysis involves heating waste tires to a specific temperature in an oxygen-deficient environment, causing the molecular structures of the polymers within the raw material to undergo varying degrees of bond-breaking reactions. The tyre pyrolysis process typically entails reactions, such as dehydration, cracking, isomerization, dehydrogenation, aromatization, and condensation.

Waste Tyre Pyrolysis Process
Classification of Tyre Recycling Pyrolysis Technologies
Based on differences in reaction conditions, tyre recycling pyrolysis technologies can be categorized into slow pyrolysis, fast pyrolysis, catalytic pyrolysis, vacuum pyrolysis, pressurized pyrolysis, microwave pyrolysis, plasma pyrolysis, hydro-pyrolysis, and co-pyrolysis.

Slow Pyrolysis
Slow pyrolysis involves the gradual decomposition of materials under conditions of slow heating. At low heating rates, organic matter decomposes slowly, and the resulting carbon black and volatiles remain in the reactor for a relatively long time. The lower the heating rate, the more frequent the secondary conversion reactions of primary products become. This results in a higher yield of char, tar, and thermally stable products.

Consequently, the slow pyrolysis process is also referred to as carbonization. Our biomass carbonization plant https://www.pyrolysismachine.com/biomass-carbonization-plant/ utilizes slow pyrolysis, primarily for the production of biochar.

Biomass Carbonization Plant
Rapid Pyrolysis
Rapid pyrolysis involves a high heating rate. In practical production, to ensure the material undergoes sufficient pyrolysis, the particle size of the feedstock must be smaller than that used in slow pyrolysis. Under rapid heating conditions, the residence time of pyrolysis-generated volatiles in the high-temperature zone is shorter, which favors the formation of liquid products. At high temperatures, high-molecular-weight tars within the primary products decompose further into low-molecular-weight hydrocarbons.

Therefore, the objective of rapid pyrolysis is to obtain liquid fuels and chemical feedstocks with high calorific values.

Catalytic Pyrolysis
Catalytic pyrolysis refers to the process of thermally decomposing material in the presence of a catalyst.

Vacuum Pyrolysis
Vacuum pyrolysis primarily utilizes a vacuum environment to create negative pressure within the pyrolysis reactor. Volatile components generated during the pyrolysis of solid waste are more easily released and discharged from the reactor under negative pressure. Compared to conventional pyrolysis environments, vacuum pyrolysis allows for control over the residence time of volatile components within the reactor, modulation of the extent of secondary reactions between products, and optimization of the structure of the tyre recycling pyrolysis products.

Waste Tyre Recycling Plant
Furthermore, vacuum conditions can lower the temperature required for tyre recycling pyrolysis, thereby reducing the high-temperature resistance requirements for equipment materials. Additionally, the residual volatile content in the carbon black obtained from vacuum pyrolysis is lower.

Ressurized Pyrolysis
Pressurized pyrolysis involves incorporating a pressure-balancing mechanism into the pyrolysis system, resulting in an internal reactor pressure that exceeds the ambient pressure. This high-pressure environment inhibits the movement of pyrolysis products, preventing volatile components from promptly escaping the pyrolytic char. Consequently, the residence time of volatile components within the reactor is extended, intensifying secondary reactions among the products.

Microwave Pyrolysis
Certain materials can absorb microwaves and convert them into thermal energy—a property that can be utilized for the pyrolysis of waste tires. Microwave pyrolysis of tires is characterized by high processing efficiency and high selectivity regarding pyrolysis oil components (particularly limonene).

Furthermore, this heating method allows for the uniform distribution of heat throughout the material. Microwave pyrolysis technology is well-suited for materials with low thermal conductivity, such as waste tires. The carbon black present in tires enhances the transfer of microwave energy to the rubber, thereby promoting the rubber’s decomposition.

Continuous Tyre Pyrolysis Plant
Plasma Pyrolysis
Plasma represents a fourth state of matter—distinct from solids, liquids, and gases—consisting of positive and negative ions generated through atomic ionization. Plasma pyrolysis technology offers numerous advantages, including compact equipment size, rapid heating rates, and the ability to quickly break down substances into small molecules.

Hydrocracking
Hydrocracking technology enables the long-chain hydrocarbons found in tire pyrolysis products to break down, thereby generating a higher proportion of saturated hydrocarbons. This process is widely utilized in petroleum refining.

Hydrocracking primarily influences the composition and quality of liquid and gaseous products, while having a minimal impact on the yield and properties of the solid char residue. Compared to the direct pyrolysis of waste tires, hydrocracking reduces energy consumption and suppresses secondary polycondensation and polymerization reactions involving the oil. This facilitates an increase in pyrolysis oil yield and a reduction in tar formation.

Batch Pyrolysis Plant for Sale to Ecuador
Co-pyrolysis
Co-pyrolysis involves the simultaneous thermal decomposition of two or more types of feedstock. Examples include the synergistic co-pyrolysis of waste tires with materials such as coal, plastics, and biomass. This technique leverages the complementary properties of the different materials during the pyrolysis process to generate synergistic effects and enhance the quality of the resulting products.

The primary objective of co-pyrolysis is to improve both the yield and quality of liquid-phase products. Waste plastics, which are rich in hydrogen, can serve as hydrogen donors to boost the yield of tire pyrolysis oil.

How to Obtain Biochar from Sewage Sludge?

keke — Tue, 01 Sep 2026 10:37:07 +0100

Mingjie biomass carbonization equipment can obtain biochar from sewage sludge by pyrolysis carbonization. It provides an effective way for the wastewater treatment industry to achieve sludge resource utilization. In an anaerobic environment, heating causes the organic matter in the sludge to undergo pyrolysis, condensation, and carbonization reactions. Ultimately, the sludge is converted into biochar and syngas.

Simultaneously, biomass carbonization plant https://www.pyrolysismachine.com/biomass-carbonization-plant/ can recover and reuse carbon, nitrogen, and phosphorus resources from sludge, achieving both environmental and economic benefits. The carbonization plant also offers advantages such as low investment and operating costs and a small footprint.

Sewage Sludge Carbonization for Biochar Conversion
Carbon sequestration is the contribution of sludge biochar to addressing climate change. The sludge biochar production equipment https://www.pyrolysismachine.com/sludge-biochar-production-equipment/ converting organic carbon in sludge into a stable biochar form allows for long-term carbon fixation. This helps reduce pollution and carbon emissions in the wastewater treatment industry.

Biochar from Sewage Sludge
Compared to straw and fruit shell biochar, biochar from sewage sludge contains its own mineral components. Its multi-level pore structure exhibits excellent removal and fixation capabilities for heavy metals, organic pollutants, and nitrogen and phosphorus in water.

Sludge biochar https://www.pyrolysismachine.com/sludge-biochar-production-equipment/ has numerous advantages, including high aromaticity, strong stability, rich pore structure, large specific surface area, and strong adsorption capacity. It holds broad application prospects in soil carbon sequestration, pollutant remediation, and soil improvement.

Among the current technologies for the resource utilization of sludge, sludge pyrolysis carbonization technology is one of the most advanced environmental protection technologies in the world.

Sludge Pyrolysis and Carbonization Process
Sludge Drying: Wastewater is dried to reduce the moisture content of sludge from high moisture content to below 15%.
Pyrolysis and Carbonization: The dried sludge is fed into a pyrolysis and carbonization furnace for the reaction. The resulting sludge char is discharged, cooled, and then sent to a char storage silo.
Pyrolysis Gas Combustion: Purified syngas enters the combustion unit to provide heat for the pyrolysis and carbonization process. To fully recover heat, the flue gas produced after combustion can be used to heat the drying system.
Flue Gas Treatment System: The flue gas is treated through denitrification, desulfurization, and dust removal processes to meet emission standards.
Sludge Carbonization Technology
Based on sludge carbonization temperature, carbonization techniques can be classified into low-temperature carbonization, medium-temperature carbonization, and high-temperature carbonization.

Low-temperature carbonization (200–400℃) has low energy consumption and retains more organic matter in the product, but the processing cycle is long.
Medium-temperature carbonization (400–600℃) has a fast reaction rate, high carbonization efficiency, and strong product stability.
High-temperature carbonization (600–800℃) achieves deep decomposition of organic matter and significant volume reduction.
Biomass Pyrolysis Carbonization Process
Advantages of Sludge Carbonization
Sludge carbonization is a thermochemical treatment method that can replace sludge incineration. It demonstrates significant advantages in sludge energy utilization, resource recovery, pollutant control, and carbon dioxide removal.

Volume Reduction: During the sludge carbonization process in a high-temperature environment, moisture is evaporated and organic matter is decomposed. Approximately 0.1 tons of sludge biochar are produced after carbonization of 1 ton of sludge. The volume reduction rate of sludge carbonization can reach about 90%.

Stabilization: Carbonization of sludge in a high-temperature, anaerobic environment completely eliminates the activity of microorganisms in the sludge. Simultaneously, easily degradable organic components in the sludge are transformed into stable aromatic carbon structures – sludge biochar. Biomass Pyrolysis carbonization achieves complete stabilization of the sludge, reducing the risk of secondary environmental pollution.

Detoxification: The high temperature and anaerobic environment during carbonization decompose pathogens, insect eggs, and organic pollutants in the sludge into smaller molecules. At the same time, heavy metals in the sludge are passivated and solidified, rendering them inactive.

Resource Utilization: The only solid product formed during carbonization is biochar. It can be used as a soil conditioner and adsorbent, achieving complete resource utilization.

Impact of Net Zero Emission Standard 2.0 on Carbon Dioxide Removal Technology

keke — Tue, 01 Sep 2026 10:20:25 +0100

In June 2026, the Scientific Carbon Targeting Initiative (SBTi) officially released the Corporate Net Zero Standard 2.0, scheduled to fully take effect in February 2027. It systematically and standardized for the first time defined the application boundaries, accounting rules, and compliance priorities of artificial carbon dioxide removal technology. This will fundamentally change the industry landscape of corporate carbon offsetting and carbon asset accounting.

This standard, through its core Ongoing Emissions Responsibility framework, is the first to incorporate carbon removal into a mandatory compliance framework for businesses. This means that purchasing carbon removal credits is no longer a “bonus” for companies, but rather an institutional requirement. It creates a large potential buyer’s market for biochar carbon removal credits.

Carbon dioxide removal technology is gradually gaining market pricing. International carbon credit certification platforms have begun issuing carbon credits for persistent carbon removal projects, such as biochar.

Net Zero Emission Standard
What is Carbon Dioxide Removal Technology?
Carbon dioxide removal technology refers to the activities that remove carbon dioxide from the atmosphere and store it permanently. It aims to address historical and residual emissions. The International Energy Agency (IEA) states that large-scale deployment of carbon removal technologies is crucial to addressing global warming.

Biochar Carbon Dioxide Removal Technology
Carbonization technology, which directly solidifies biomass into biochar, is one of the important negative emission technology pathways for achieving long-term carbon storage. Compared to BECCS (Biochemical Oxygen-Free Carbon Sequestration System), biochar is not limited by geological sequestration capacity.

In recent years, novel carbon dioxide removal technology has attracted significant attention, such as direct air capture (DAC), biochar, BECCS, biomass storage, and enhanced weathering. However, the reality is that global carbon removal still heavily relies on traditional natural carbon sinks. Biochar holds a leading position in the field of CDR. It has the largest delivered carbon removal capacity and the most widespread global distribution.

Biochar has the potential to achieve substantial production within a decade. Currently, carbon credits are priced between $100 and $200 per tonne. Its cost-effectiveness far surpasses that of Direct Air Capture (DAC) and it is also competitive with earlier bioenergy carbon capture and storage (BECCS) technologies.

How Biochar Effectively Reduces Carbon Dioxide?
Biomass pyrolysis https://www.pyrolysismachine.com/biomass-pyrolysis-plant/ carbonization technology is currently the most scalable, low-cost, and highly stable negative carbon dioxide removal technology. It is the core pathway for enterprises to offset residual carbon emissions and cultivate carbon sink assets.

Biomass carbonization plant converts biomass into biochar through thermochemical treatment under anaerobic conditions. This process locks carbon, which would otherwise return to the atmosphere through natural decomposition or incineration, into a stable, long-term form within a solid material.

The core logic of this process lies in altering the natural carbon cycle. Under natural conditions, carbon fixed by plants through photosynthesis is decomposed into carbon dioxide by microorganisms and released back into the atmosphere after the plants die. Biomass carbonization plant, through artificial intervention, transforms this “carbon source” process into a “carbon sink” process. The carbon in biomass is converted into highly aromatized biochar, which has a half-life in soil that can reach hundreds or even thousands of years.

Carbon Removal Mechanism of Biomass Carbonization Equipment
The contribution of biomass carbonization plant https://www.pyrolysismachine.com/biomass-carbonization-plant/ to carbon removal is primarily reflected in the physical sequestration of carbon. During the carbonization process, the carbon in the biomass raw materials is fixed in the solid structure of biochar. This avoids carbon dioxide emissions from natural decomposition or incineration.

The carbon sequestration effect is even more significant when biochar is applied to the soil. Applying 1 ton of biochar is equivalent to removing 1.5 tons of carbon dioxide. This ratio reflects the net carbon removal efficiency of biochar throughout its entire life cycle.

From a microscopic perspective, biochar has a well-developed porous structure. This porous structure not only enhances the physical protection of carbon in the soil but also provides the structural basis for its adsorption and fixation of carbon dioxide from the environment.

On July 24, 2026, Mingjie engineers were installing the waste plastic to diesel plant in Vietnam. The complete waste plastic to diesel system consists of two main units: plastic pyrolysis system and pyrolysis oil distillation system. These are key industrial equipment for solving plastic pollution and developing alternatives to fossil fuels.

Waste Plastic Pyrolysis Plant
The waste plastic to diesel plant https://www.pyrolysismachine.com/waste-plastic-to-diesel-plant/ offers a technological path that combines environmental value with economic potential. Through pyrolysis and refining processes, it converts waste plastics into high-value diesel fuel. This waste plastic into diesel conversion technology is moving from the laboratory to large-scale industrial application, becoming an important direction in the circular economy.

How a Waste Plastic to Diesel Plant Works
This waste plastic to diesel plant primarily employs pyrolysis and distillation purification processes.

The core of producing diesel from waste plastic lies in the pyrolysis plant https://www.pyrolysismachine.com/pyrolysis-plants-2/. Under anaerobic or oxygen-deficient conditions, the pyrolysis equipment heats the plastic to 300-600℃, causing the long-chain polymer molecules to undergo chain-splitting reactions, decomposing into a mixture of hydrocarbons with shorter carbon atoms. These products escape in gaseous form and are collected by condensation to obtain crude pyrolysis oil.

Crude pyrolysis oil already contains the main components of diesel (such as C10-C22 alkanes), but it contains many impurities and requires further refining to meet commercial diesel standards.

Plastic Pyrolysis Oil To Diesel
The crude pyrolysis oil is then separated into diesel fractions through vacuum distillation. Further processes such as acid washing, alkali washing, and adsorption remove impurities such as sulfur, nitrogen, pigments, and gum. The final product is a diesel product with quality close to commercially available standards.

Core Structure of Waste Plastic to Diesel Plant
A complete waste plastic to diesel plant typically includes the following core systems: feeding system, pyrolysis reactor, condensation and oil-gas separation system, distillation and refining system, slag discharge system, exhaust gas treatment system, and PLC control system.

Feeding System: Employs a screw feeder to achieve closed-loop feeding, preventing air ingress and potential safety hazards.

Pyrolysis Reactor: A rotating reactor with an external heating chamber to ensure uniform heating of the material.

Feeding System
Condensation and Oil-Gas Separation System: A horizontal composite condenser with indirect cooling via circulating cooling water, rapidly liquefying the mixed oil and gas. A buffer tank and oil-water separator separate free water from crude oil, preventing water from entering the reactor.

Distillation System: Consists of a vacuum distillation reactor, heating device, negative pressure unit, fractionation tower, and condensate collection tank. Low-temperature fractionation under negative pressure precisely cuts the diesel fraction.

Refining Unit: Includes pickling tank, alkali washing tank, and adsorption filter, used to remove sulfides, colloids, and pigments from pyrolysis oil.

Solid Residue Discharge System: Water-cooled, sealed, and automatically discharges residual carbon black from pyrolysis, eliminating dust pollution.

Tail Gas Treatment System: The combustion flue gas from the reactor sequentially passes through dust removal, spray washing, and activated carbon adsorption purification systems. Particulate matter, VOC, and dioxin emissions all meet domestic and EU environmental standards.

Intelligent Control System: Precisely controls temperature, pressure, and feed rate to ensure long-term continuous operation.

Suitable Plastics for Plastic to Diesel Plant
The optimal plastic raw material is polyolefin hydrocarbon structure. It boasts an oil yield of 65%~75%, high-quality diesel fuel, and low equipment wear. Its pyrolysis byproducts are pure, and the distilled diesel fuel has a high proportion of light oil, making it the main raw material for plastic-to-diesel production.

Plastic Type
PE (Polyethylene): Highest oil yield, moderate wax content, clear distilled diesel fuel with minimal coking.

HDPE (High-Density Polyethylene): Plastic buckets, plastic jugs, plastic pipes, detergent bottles
LDPE/LLDPE (Low-Density Polyethylene): Agricultural film, supermarket plastic bags, packaging film, express delivery stretch film
PP (Polypropylene): Disposable lunch boxes, plastic woven bags, plastic baskets, automotive plastic interiors, plastic bottle caps. Its advantages include a high proportion of light oil from pyrolysis, good diesel fuel flowability, and resistance to solidification at low temperatures.

PS (Polystyrene): Appliance foam packaging, takeout foam boxes, foam cushioning fillers. Its advantages include easy pyrolysis, fast oil yield, and a high proportion of light oil components.

ABS (Polyethylene terephthalate): Used to manufacture plastic parts for appliance casings, keyboards, and luggage. It contains a small amount of benzene rings, and the cracked oil has a slightly strong odor. Processing it alone tends to produce a relatively heavy oil. Co-pyrolysis with up to 20% PE/PP can improve the oil quality.

EVA plastic: Can be blended with small amounts of pure polyolefins. Processing it alone tends to produce a small amount of gel. Distillation requires additional filtration and decolorization processes.

In summary
With breakthroughs in continuous pyrolysis technology https://www.pyrolysismachine.com/continuous-pyrolysis-plant/ and intelligent control systems, coupled with the ongoing global demand for carbon reduction and a circular economy, the plastic pyrolysis recycling industry is entering a period of opportunity for large-scale development. Waste plastic to diesel plant is not only a key to solving white pollution, but also a bridge connecting waste management and clean energy supply.

Distillation equipment can separate gasoline and diesel fractions, while acid-base washing refining system can remove impurities and improves the quality of the diesel fuel.

Waste Oil Distillation to Bright-Colored Fuel Oil
Distillation: Separation of Gasoline and Diesel
The MJZ-2 pyrolysis oil distillation plant for sale https://www.pyrolysismachine.com/pyrolysis-oil-distillation-plant-for-sale/ adopts negative pressure distillation. Negative pressure distillation is currently the mainstream upgrading process for refining pyrolysis oil. It relies on a vacuum pump to create a sealed vacuum negative pressure environment, significantly reducing the boiling points of various hydrocarbon fractions. This allows for the separation of gasoline, diesel, and heavy tar at low temperatures.

Why Choose Negative Pressure Distillation?
For pyrolysis oils with complex compositions and high heat sensitivity, negative pressure distillation offers several advantages.

Avoids High-Temperature Coking: This is its greatest value. Pyrolysis oils contain large amounts of gums and asphaltenes, which readily coke and carbonize on the inner walls of the equipment at high temperatures. Negative pressure distillation lowers the operating temperature. This significantly reduces the risk of coking, ensuring the long-term stable operation of the distillation equipment.

Improved Product Quality and Yield: The low-temperature environment prevents secondary cracking and polymerization of unsaturated hydrocarbons in the oil, protecting the molecular structure of diesel components. Simultaneously, the high separation efficiency effectively increases the yield of diesel and gasoline components.

Reduced Energy Consumption and Operating Costs: A lower boiling point means less heat is required for heating, thus reducing energy consumption.

Enhanced Operational Safety: The entire system operates under negative pressure and low oxygen conditions, reducing the risk of oil oxidation and combustion.

Effective Deodorization and Decolorization: The negative pressure environment facilitates the vaporization and separation of low-molecular-weight substances that produce odors. This improves the color and odor of the oil.

Pyrolysis Oil Refining for Diesel Fuel Conversion
Acid-Base Washing: Diesel Oil Refining and Purification
Acid-base washing is the most traditional and widely used chemical refining method in pyrolysis oil refining. Its core principle is to remove impurities through acid washing, followed by neutralization of acidic substances through alkali washing. Ultimately, qualified diesel oil is obtained.

Acid Washing
Acid washing is the first step in the refining of pyrolysis oil. The distillate oil obtained after pyrolysis oil distillation is pumped into an acid washing tank, where a certain proportion of concentrated sulfuric acid is added and the mixture is thoroughly stirred. The sulfuric acid reacts with impurities in the oil, producing acid sludge and other substances. This acid sludge has a high density and separates from the oil layer. It is removed by sedimentation.

Water Washing and Alkali Washing
The acid-washed oil contains residual sulfuric acid and water-soluble impurities generated from the reaction. It needs to be washed with a large amount of water, and then enters the alkaline washing process. The acidified oil is placed into an alkaline washing tank, where a certain proportion of NaOH solution is added and stirred.

The core functions of alkaline washing include neutralizing acidic substances, removing thiols, and improving color and odor.

Decolorization and Filtration
Crude oil may still contain some impurities and pigments after acid and alkali washing, requiring decolorization treatment. The crude oil is pumped into a decolorization tank, and activated clay is added and thoroughly stirred. The adsorption properties of the activated clay remove pigments and other impurities. The mixture is then sent to a filter to remove the waste activated clay, followed by fine filtration. Finally, clean, bright-colored non-standard diesel oil is obtained.
