摘要：Three activated carbon samples were synthesized via the template synthesis, in which a polymer was impregnated into the porous networks of zeolite Y and carbonized at three different temperatures. The carbon samples were structurally characterized and examined, respectively, for the application of energy gas (CH4 and H2) storage. It was found that (1) at high pressure end (P > 35 bar) the methane storage capacity is approximately proportional to the surface area while the hydrogen storage capacity is predominated by the volume of micropores; (2) at low pressure end (P < 1bar), however, the adsorption capacity is a strong function of the size and volume fraction of micropores/small micropores. The role of mesopore, micropore, and small micropore was discussed in details with respect to the adsorption of H2/CH4.
