1. Wood activated carbon: Wood activated carbon refers to the activated carbon products made of wood, crop straw, bamboo and its processing waste and fruit shells as raw materials can be divided into wood activated carbon (such as coconut shell activated carbon, apricot shell activated carbon, wood powder charcoal, etc.).
2. Mineral raw material activated carbon: This type of activated carbon mainly refers to activated carbon made from various coal and petroleum and their processing products (including coal tar, coal pitch, coal semi-coke, petroleum hydrocarbons, petroleum residue, petroleum pitch, petroleum coke, etc.) as raw materials.
3. Activated carbon of other raw materials: In order to meet the needs of scientific research and special uses and expand the source of activated carbon raw materials, activated carbon can also be manufactured as raw materials with synthetic resin, waste rubber, organic matter in domestic and industrial waste. Now there are metal carbides as raw materials, the metal is removed and the activated carbon with particularly developed holes is manufactured.
4. Recycled activated carbon: In order to make full use of resources, many activated carbons that have been used and lost their adsorption properties have been processed in different ways and recovered all or part of their adsorption properties for reuse in different occasions. The process of restoring the adsorption activity of the activated carbon that has lost its adsorption property is called activated carbon regeneration, and the activated carbon processed through the regeneration process is called recycled activated carbon. Regeneration methods include thermal regeneration. Chemical elution, solvent extraction regeneration, biological regeneration, etc.
