In this work, activated carbons (AC) with high specific surface area were synthesized by chitosans which generally known as abundant polysaccharide. Carbon materials were prepared at 900℃, 1h, and N2 flow conditions using chitosans as precursor. After carbonized, AC was synthesized by chemical activation. The effect of quantity of activation reagents was investigated by experience of AC/chemical reagent mass ratio. The structure information of the activated carbons was measured by X-ray diffraction (XRD) patterns. The N2 adsorption-desorption isotherms were measured at 77 K and calculated by Brunauer-Emmett-Teller (BET) equation. The morphology of prepared material was observed using scanning electron microscopy (SEM). Methane storage capacity was evaluated with a Model BEL-HP instrument (BEL Co., Ltd., Japan) at 298 K and 35 bar.
