Core Values Created by BST-50S Biochar Pyrolysis Equipment
7,200H/Y Continuous Operation
During biochar pyrolysis process, tar, wood vinegar, and biochar particles can easily cause blockages, interrupting continuous operation. To overcome these issues, BST-50S integrates 2 core safeguards:
- No Tar and Wood Vinegar Precipitation
Pipeline insulation and temperature-control components keep system consistently heated, preventing tar and wood vinegar from condensing. - No Dust Accumulation and Blockage
Specialized cleaning devices regularly remove biochar debris and dust that would otherwise adhere to deposits and form stubborn blockages.
6,000T/Y Biochar Production
Stable high output depends on both large feed capacity and precise thermal control. The equipment ensures reliable biochar yield through the following design strengths:
- Dual-Cylinder Structure for Large Feed Capacity
Inner cylinder dries biomass, while outer cylinder completes pyrolysis. It enables multi-stage carbonization, with throughput exceeding 10 m³/h. - High-Temperature Pyrolysis for Premium Biochar
Temperature control maintains precise thermal conditions for pyrolysis of biomass. This guarantees stable H/C ratios and low PAHs, producing consistent, high-quality biochar.
Integrate dMRV System to Drive Biochar Carbon Removal Project
What Is LCA?
Life Cycle Assessment (LCA) is a scientific quantitative analysis method that systematically analyzes the resource consumption and environmental impact of a product or service throughout its entire lifecycle (from raw material acquisition, manufacturing, transportation, use to final disposal/recycling).
What Is dMRV?
dMRV (Data Management, Reporting, and Verification) is a digital monitoring system that utilizes technologies such as the Internet of Things (IoT), satellite remote sensing, artificial intelligence (AI), and blockchain. It transforms the traditional, manual process of calculating greenhouse gas emission reductions into a fully digital and automated system.
dMRV system provides all the operational data for the biochar project, while LCA uses this data to evaluate the environmental impacts, thus determining the project’s net carbon removal effect and its lifecycle carbon footprint.
- 1Feedstock Sourcing StagedMRV records actual feedstock quantities, sources, transportation distances, and energy consumption.
- 2Biochar Pyrolysis Production StagedMRV monitors actual pyrolysis temperature, residence time, output volumes, carbon content, and energy use.
- 3Biochar Quality Testing StagedMRV digitally records laboratory test results, tracks fixed carbon content, H/Corg ratio, etc.
- 4Biochar Transportation StagedMRV tracks actual transport routes, transported volumes, and fuel consumption.
- 5Biochar Application Stage dMRV tracks the location of application sites, application quantities, and application scenarios (e.g., soil, construction materials, etc.).
- 6Carbon Removal Calculation StageGenerates an LCA report based on full-lifecycle dMRV data. The certification platform verifies carbon removal effects and issues carbon credits accordingly.

Operation Stages of Pyrolysis Machine for Biochar
01 Feeding Stage
The biomass size of the feed is no larger than 20mm, the moisture content is no higher than 15%, and it has good fluidity. This avoids feed blockage caused by material sticking or agglomeration. You can ensure that the waste meets the feed conditions through drying, crushing and screening systems. Beston Group provides the corresponding equipment.
02 Pyrolysis of Biochar Stage
- Preheating: The burner quickly brings the rotating reactor to optimal pyrolysis temperatures, ensuring a fast start-up.
- Further Drying: The inner barrel removes moisture. It prevents energy loss and optimizing the material for the next phase.
- Deep Carbonization: In the outer barrel, biomass undergoes thermal decomposition under oxygen-deficient conditions. Finally, biochar is formed.
03 Combustible Gas Reuse Stage
- Gas Generation: Inside biochar reactor, the organic components in the material will decompose and produce combustible gases (such as carbon monoxide, methane, etc.). These gases enter the dust removal device to remove solid particles and impurities.
- Fuel Recovery: The combustible gas after dust removal enters the combustion system through the pipeline. It serves as fuel to further provide the heat energy required in the biochar pyrolysis equipment.
- Excess Gas Treatment: Excess combustible gas enters the exhaust combustion chamber and is directly burned. Or you can use a special device to collect it.
04 Biochar Collection Stage
The biochar is usually discharged from biochar pyrolysis reactor by a screw conveyor. Too high a temperature of the biochar can lead to a reduction in quality or the risk of spontaneous combustion. Therefore, the screw conveyor is water-cooled. In addition, this prevents the biochar from coming into contact with hot flue gases, thus ensuring the purity of the biochar.
05 Gas Treatment Stage
The waste flue gas that no longer participates from pyrolysis of biochar will be cooled and dust-removed. The waste gas undergoes a series of treatments: heat exchanger → bag filter → desulfurization tower → activated carbon dust collector. The treated waste flue gas is discharged through the chimney. This not only meets environmental protection standards, but also reduces the impact on air quality.
Material Changes of Biomass During Biochar Pyrolysis Process
In the pyrolysis equipment for biochar, organic materials in biomass like lignin, cellulose, and hemicellulose undergo significant changes as they break down into different volatile compounds and finally form biochar. Generally, biomass rich in lignin, such as coconut shells and wood, produces more biochar during pyrolysis.
Stage I: Volatile Release (200℃~350℃)
Component Evolution:
- Cellulose/Hemicellulose: Decompose rapidly at 200°C ~ 350°C, releasing volatile gases like CO₂, CO, CH₄, and organic acids.
- Lignin: Begins to decompose around 300℃, releasing CO₂, CH₄, phenols, alcohols, and esters.
Property Formation
- Porous Structure: Volatile release causes breakdown of fiber bundles, forming nano-sized channels. It increases surface area, enhances adsorption capacity, and reduce material density.
- Functional Groups: Carboxyl (-COOH) and hydroxyl (-OH) groups form on the surface. It increases surface reactivity and enhances cation exchange capacity (CEC), while imparting mild alkalinity.
Stage Ⅱ: Biochar Formation (350℃~500+℃)
Component Evolution
- Cellulose/Hemicellulose: Gradually decomposes completely and integrates into the solid carbon structure.
- Lignin: Decomposes more slowly and undergoes deep carbonization, forming stable carbon ring structures through aromatic reactions.
Property Formation
- Aromatic Structure: Carbon atoms form stable six-membered ring chains. It gives biochar biochemical stability against microbial degradation and limit heat transfer.
- High Fixed Carbon Content: Hydrogen and oxygen are completely removed, resulting in a high concentration of carbon, which exhibits excellent reducibility and high calorific value.
