The selection of raw materials for activated carbon production is diverse. Common categories include:
Wood: Pine, fir, birch, etc.
Sawdust: Byproducts from wood processing.
Fruit Shells: Coconut shells, walnut shells, apricot shells, etc.
Anthracite: High carbon content, suitable for producing high-hardness activated carbon.
Bituminous Coal: High carbon content, ideal for activated carbon with strong adsorption performance.
Lignite: Lower carbon content but offers good pore structure.
Asphalt: Derived from petroleum or coal tar, used for high-performance activated carbon.
Petroleum Coke: A byproduct of petroleum refining, suitable for high-purity activated carbon.
Bamboo: Bamboo and its processing byproducts.
Crop Straws: Agricultural residues like rice straw, wheat straw, etc.
Waste Tires: Rubber components can be converted into activated carbon.
Used Activated Carbon: Can be regenerated and reused.
Carbon Content: Higher carbon content is preferable.
Ash Content: Low ash content improves activated carbon quality.
Pore Structure: A well-developed porous structure enhances adsorption capacity.
Cost: Raw material costs impact overall production expenses.
Wood-based, coal-based, mineral-based, and other materials can all be used for activated carbon production. The specific choice depends on product requirements, performance goals, and cost considerations.
