Granular Activated Carbon for Solvent Recovery

Product Description
The granular activated carbon used for solvent recovery is made from high
quality anthracite coal as raw material and refined by physical activation
method. It is black granular, non-toxic and tasteless, with developed pores,
reasonable distribution of three types of pores and strong adsorption
capacity. In a wide concentration range, GAC has stronger adsorption
capacity for most of the organic solvent vapor. It is widely used in organic
solvent recovery, such as benzene, ether, xylene, ethanol, acetone, gasoline,
chloroform, carbon tetrachloride and so on. Granular activated carbon has the
characteristics of high strength, fast adsorption speed, high adsorption
capacity, large specific surface area, developed pore structure, moderate pore
size, etc.
The solvent recovery process using granular activated carbon is to pass the
mixed gas containing organic solvent vapor into the reactor filled with
activated carbon. The solvent vapor is adsorbed on the granular activated
carbon by the strong selective adsorption capacity of granular activated
carbon, and the purified air removing the solvent vapor flows out from the
other end of the reactor. After the granular activated carbon is saturated,
it stops adsorption and then regenerates. When it is regenerated, water vapor
is generally used to remove the solvent adsorbed on the activated carbon, and
then the desorption vapor is condensed and the organic solvent is recovered.
The regenerated granular activated carbon is dried and cooled for recycling.
