The production process of coconut shell activated carbon mainly consists of several core steps: raw material screening, carbonization, activation, post-treatment, and packaging. Let me summarize them for you:

Raw Material Screening and Pre-treatment: Select high-quality coconut shells (Indonesian coconut shells are often preferred due to their high density and quality), remove impurities, crush into 2-3 cm pieces, and dry until the moisture content is below 15%.

Carbonization: Heating at high temperature (400-600℃) in an oxygen-deficient environment causes the coconut shells to pyrolyze, volatilizing moisture and organic matter, forming a porous carbon structure.

Activation: Treating the carbonized material with high-temperature steam or chemical agents further expands the pores and increases the specific surface area. This is a crucial step determining adsorption performance.

Post-treatment and Screening: After cooling, crush and screen the material according to particle size requirements (e.g., 6-12 mesh, 8-16 mesh). Chemical activation also requires acid washing to remove residues.

Packaging: Moisture-proof and sealed packaging, commonly 25 kg/bag or ton bag. The entire process has very high requirements for process parameters such as temperature and time to ensure the adsorption performance of the final product.
