For practical energy utilization, efficient storage materials of alternative fuel are essential. There are various types of adsorption materials studied for gas storage. In this work, corn starches-based activated carbons were prepared by chemical activation process. The influence of activation reagent ratios was investigated by experience of activated carbons/chemical reagents mass ratio. The structural information of the activated carbons was measured by X-ray diffraction (XRD) patterns and scanning electron microscopy (SEM). The N2 adsorption-desorption isotherms were measured at 77 K and calculated by Brunauer-Emmett-Teller (BET) equation. Methane storage capacity was evaluated with a Model BEL-HP instrument (BEL Co., Ltd., Japan) at 298 K and 35 bar. |
