Abstract

Carbon adsorption was selected as a means of efficiently storing methane, the main component of natural gas. Simulations were first employed to determine an ideal adsorptive pore structure. The results of the simulations were established as a target in the manufacture of activated carbon, with coconut shell, coal and carbon nano-materials (Buckminsterfullerene, carbon nano-tubes) as starting materials. TEM analysis confirmed that the activated carbon produced in this research possessed the ideal pore structure established as a target. This activated carbon is capable of storing 0.155NL/cm3 of natural gas at low pressure (3.5MPa). This represents 77.5% of the capacity of high-pressure (20MPa) compressed natural gas (CNG) storage. The material’s storage capacity for adsorbed methane gas is in the world’s top class of presently reported figures.
