Improvement of Methane Storage Capacity for Active Carbons

Abstract

A method for increasing storage capacity by working of the commercial active carbons in a spouted bed is proposed. By abrasion of external layers of grain active carbons with better adsorptive properties, smaller voids of bed and improved attrition strength was obtained. Investigations of methane storage capacity for active carbon NORIT R2 with different degrees of external layers removed, were carried out. Experiments indicate that methane storage capacity can be increased up to 15–20% over commercial carbon.
