Charcoal Made from Coconut Shell
How to Make Charcoal from Coconut Shell: Working Process
Step 1: Coconut Shells Pretreatment
You need to determine whether further drying or crushing is necessary based on the moisture content and size of the coconut shell raw material.
Crushing (optional): Use a crusher to process coconut shells into target sizes (less than 20mm).
Drying (optional): Use a dryer to keep coconut shells’ moisture content below 15%.
Step 2: Coconut Shells Pyrolysis
Feeding: Screw belt conveyor transports coconut shells into the biochar reactor. Make sure the reactor is tightly sealed to maintain a low-oxygen environment. This prevents the shells from burning completely and turning to ash.
Heat Reactor: Ignite the combustion chamber to gradually heat the reactor. Aim for a temperature range of 250°C to 450°C.
Pyrolysis Process: As the temperature rises, the coconut shells begin to undergo thermal decomposition. During this phase, the volatile gases and liquids are released, leaving behind solid carbon-rich biochar/charcoal.
Cooling Discharging: Allow the reactor to cool down with the water-cooling system. Do not open the furnace immediately, as sudden exposure to air can cause the charcoal to ignite. After cooling, carefully collect the charcoal.

Core Quality Indicators
High Fixed Carbon Content (>75%): Beston biochar machine uses precise high-temperature, oxygen-limited pyrolysis to maximize the conversion of organic matter in coconut shells into stable fixed carbon. The final biochar exceeds 75% fixed carbon content, ensuring long-term stability and efficient carbon removal effect.
Low H/C Mole Ratio (<0.4): Through complete pyrolysis, the volatile components, as well as hydrogen and oxygen elements, are effectively driven off, resulting in a highly aromatic and stable carbon structure. This lowers the H/C mole ratio to well below 0.4, meeting the stringent EBC standard.
Environmental Compliance
Heavy Metal Control: Coconut shells naturally contain very little heavy metal. Furthermore, Beston charcoal machine’s sealed design and high-temperature control prevent heavy metal migration. The levels of As, Cd, Pb, and other heavy metals in the biochar remain within the strict EBC limits, avoiding contamination of soil and water sources.
Organic Pollutant Control: Polycyclic aromatic hydrocarbons (PAHs) primarily arise from incomplete combustion. Beston biochar machine optimizes temperature control and syngas recycling system, ensuring clean and complete combustion. This minimizes the formation of PAHs, ensuring the biochar meets EBC standards.

FAQs of Making Charcoal from Coconut Shell
Feedstock & Feeding Constraints
01What are the size and moisture requirements for coconut shells before feeding into the biochar machine?
To ensure continuous and efficient pyrolysis, coconut shells must meet these raw material limits:
Moisture: Below 15%
Size: Under 20mm
If your feedstock exceeds these limits, Beston highly recommends integrating a dedicated crusher and dryer into your configuration.
02Does the remaining coconut fiber (coir) on the shell affect the charcoal quality?
A small amount of residual fiber will not significantly affect the machine’s operation, but because fiber has a lower density than the hard shell, it carbonizes much faster and may turn to ash if over-processed. For premium coconut shell biochar, using clean, separated shells yields the highest fixed carbon content.
03Can I mix coconut shells with other biomass (like palm kernel shells or sawdust) for simultaneous processing?
No. Different biomass materials cannot be mixed and processed at the same time. Because the processing capacity, charcoal quality, and optimal temperature vary by material, you will need to adjust operational parameters (such as feeding rate, reactor speed, and fan frequency) for each specific feedstock based on testing reports.
Process Control & Operating Parameters
04What are the carbonization temperature and the furnace temperature during continuous operation?
For processing biomass like coconut shells, the operating temperatures are strictly regulated:
Carbonization Temp (inside reactor): 380°C – 450°C. Ideal range for high-fixed-carbon biochar.
05 How do you control the discharge temperature to prevent spontaneous combustion?
The machine features a water-cooled discharging system. Dual-layer water-cooling pipeline rapidly cools the charcoal down to 30°C – 40°C before it is discharged, eliminating the risk of fire and ensuring immediate, safe storage.
06How is the temperature monitored and adjusted during continuous operation?
The machine is equipped with multi-point thermocouples integrated into a central PLC (Programmable Logic Controller) panel. Operators can monitor real-time temperature fluctuations and adjust the feeding speed or burner intensity directly from the control room.
Energy Consumption & Environmental Control
07What types of fuel can be used for the initial preheating, and how long does the preheating process take?
Initial heating takes about 1 to 1.5 hours using diesel, natural gas or LPG. Once the pyrolysis begins, the combustible gas recycling system takes over, and the machine requires almost zero external heating fuel for continuous operation.
08Does the water-cooling discharging system consume a lot of water?
A small amount of residual fiber will not significantly affect the machine’s operation, but because fiber has a lower density than the hard shell, it carbonizes much faster and may turn to ash if over-processed. For premium coconut shell biochar, using clean, separated shells yields the highest fixed carbon content.
09Will the process generate black smoke or odor?
The process is strictly eco-friendly. The exhaust gas undergoes multiple dedusting treatments, typically including:
Water Spray Tower (desulfurization and cooling)
Cyclone Dust Collector (particulate removal)
Activated Carbon Adsorption (optional for strict emission standards)
The final emission strictly complies with European and standard international environmental regulations.
