Mingjie palm kernel shell biochar machine utilizes continuous pyrolysis technology, and is the core equipment for large-scale biochar production. We equip it with an advanced exhaust emission system, significantly reducing environmental impact.
Palm kernel shell (PKS), a core byproduct of the palm oil processing industry, has high density, low moisture content, and stable calorific value. It is an ideal raw material for producing high-quality biochar. Palm kernel shell charcoal is widely used in fuel replacement, activated carbon production, and soil improvement. It offers both economic and environmental benefits.
Environment Impact of Palm Kernel Shell Biochar Machine
Near-zero exhaust emissions: The palm kernel shell biochar machine is equipped with a three-stage exhaust gas treatment system. Including condensation recovery, desulfurization and dust removal, activated carbon adsorption.
-
The first stage uses a condensation tower to recover over 95% of tar.
-
The second stage utilizes a cyclone separator and wet desulfurization to remove over 90% of particulate matter and SO₂.
-
The third stage uses an activated carbon adsorption tower to treat residual VOCs, resulting in exhaust gas particulate matter levels far below national standards.
Energy Recycling: The biochar production equipment purifies the combustible gases generated by pyrolysis and reuses them for furnace heating, replacing external fossil energy sources. This allows for energy self-sufficiency rates exceeding 70%. The Mingjie palm kernel shell biochar machine also features a waste heat recovery system. This system uses waste heat from the exhaust to generate steam for drying, significantly reducing its carbon footprint.
Controllable solid waste and wastewater: The biochar produced by the continuous biomass pyrolysis machine can be used to make charcoal powder or charcoal pellets, achieving a 100% solid waste resource recovery rate. The cooling process utilizes a closed water circulation system, achieving zero wastewater discharge.
Mingjie Biomass Carbonization Equipment can convert palm kernel shells into biochar. Below is a detailed description of the palm kernel shell biochar production process.
Palm Kernel Shell Biochar Production Process
-
Pretreatment: The palm kernel shells are screened and crushed to remove impurities and moisture. The moisture content of the raw material is generally required to be less than 15%.
-
Drying: The pretreated palm kernel shells are fed into the carbonizer, where they are first dried at approximately 300°C to remove moisture.
-
Pyrolysis Carbonization: In an oxygen-free environment, the temperature of the carbonization reactor is raised to approximately 600°C and maintained for 40-60 minutes. This causes the palm kernel shells to undergo dry distillation, producing fixed char.
-
Cooling: The carbonized palm kernel shell char is rapidly cooled by a cooling device to prevent oxidation. After cooling, the palm kernel shell charred material is obtained.
One ton of palm shells can yield approximately 0.3 tons of biochar. Processing into activated carbon offers even greater added value. Demand for palm shell activated carbon has been on the rise in recent years, particularly in environmental protection and water treatment.
While palm shell raw material costs are relatively low, the market prices of the carbonized material. And activated carbon are relatively high, It offers considerable profit margins.
