Production of Highly Porous Carbon Sorbents for Methane Storage from Coal, Coke, and Individual Organic Compounds

摘要

Highly porous carbon sorbents for methane storage are produced from coal, coke, and individual organic compounds. A static high-pressure volumetric system is used to establish the dependence of the methane and hydrogen adsorption on the micropore volume in the sorbents. The mean specific adsorption of CH_4 and H_2 at 60 atm (6 MPa) and 300 K is ~150 and ~6.5 mg/cm~3, respectively. The results confirm physical adsorption of the gases (CH_4 and H_2).
