Abstract
The method enables control over carbon pore structure to provide sorbents that are particularly advantageous for the adsorption of specific gases. It involves preparation of a sorbent precursor material, carbonization of the precursor material, and, usually, activation of the carbonized material. The resultant material is subjected to heat treatment and/or to surface conditioning by a reducing gas at elevated temperatures.
