What are the raw materials for preparing activated carbon?
There are many types of raw materials for producing activated carbon. Almost all carbon-containing raw materials can be used as raw materials, among which coal accounts for more than half of its total consumption. Currently, the raw materials for preparing activated carbon can be mainly divided into the following categories. 1. Plant raw materials (woody raw materials) Activated carbon has a wide range of wood raw materials, and the commonly used ones are: charcoal, coconut shells, sawdust, bark, walnut shells, fruit cores, cotton shells, rice husks, bamboo, coffee bean stems, oil palm shells, furfural residue and pulp waste liquid etc. 2. Coal raw materials Coal is an important raw material for manufacturing activated carbon. Activated carbon can be made from almost any coal. Among them, young anthracite coal with a short coal formation time, weakly caking coal, lignite and peat are all excellent raw materials for making activated carbon. Due t...
