Raw materials for production
Activated carbons can be obtained from a variety of carbon-containing raw materials – wood, coal and brown coal, peat, etc.
In the industrial production of activated carbons, coal, coconut shells, and wood are most often used as raw materials.
First, carbon-containing raw materials are subjected to carbonization – roasting at high temperatures in an inert atmosphere without air access. However, the resulting carbonization has poor adsorption properties, since its pore sizes are small and the internal surface area is small. Therefore, the carbonization is subjected to activation to obtain a specific pore structure and improve the adsorption properties.
Coal production equipment
For the production of activated carbon, furnaces of various types and designs are used.
The most widespread are multi-shelf, shaft, horizontal and vertical furnaces, as well as fluidized bed reactors.
