Using granular activated carbon prepared from oil palm shell by ZnCl2 and physical activation for methane adsorption

Granular activated carbons for methane adsorption have been prepared by impregnation of oil palm shell with various solutions of ZnCl2 followed by heat treatment at 500 degrees C under a flow of nitrogen. For this precursor, large micropore volume of micropores (with a very small volume of mesopores...
