In recent years, methane storage has attracted attention as alternative fuel because of environmental problems. Methane gas has various attractive advantages such as abundance of resources and lower carbon emissions resulting from a low carbon/hydrogen ratio. For practical energy utilization, efficient storage materials of alternative fuel are essential. 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 N2 adsorption-desorption isotherms were measured at 77 K and calculated by Brunauer-Emmett-Teller (BET) equation. The pore size distributions were investigated using non-local density functional theory (NLDFT). Methane storage capacity was evaluated with a Model BEL-HP instrument (BEL Co., Ltd., Japan) at 298 K and 35 bar. |
