Methane storage in a template-synthesized carbon

Methane adsorption was investigated in a template carbon synthesized with sucrose as carbon precursor and ammonium-form zeolite Y as template. The carbon sample possesses a surface area of similar to 1500 m(2)/g and is comprised of both micropores and mesopores. Adsorption experiments show that the carbon presents a methane sorption capacity of 8.0 mmol/g at 300 K and 35 bar. The low bulk density of the as-synthesized carbon powder was improved by the fabrication of carbon pellets on which a volumetric methane storage capacity of 93 (v/v) was achieved.
