Chemical Vapor Deposition and Activation Temperature on two important microporosity properties and density of methane storage capacity of active carbon based on anthracite

The present study investigates the effect of preparation variables of AC on the optimum amount of BET surface area and bulk density for methane adsorption purposes. All activated carbons samples were synthesized through the chemical activation method, using KOH chemical agent. The effect of preparation parameters including chemical impregnation ratio and activation temperatures was evaluated on two important characteristics of microporosity and bulk density. The best performance of the AC sample was observed at a KOH/anthracite chemical ratio of 3, activation temperature of 730ºC. At the optimum condition, the activated carbon acquired convenient microporosity in the matrix structure, with BET surface area of 2160 m2/g packing density of 0.53 g/cm3 and methane adsorption capacity of 175 V/V.
