Porous carbons were prepared by a chemical activation method from ion-exchangeable resin with different impregnation ratio of KOH, and the adsorption characteristics of the porous carbons were investigated. The textural properties were studied by BET, D-R, and BJH methods with N2/77K adsorption isotherms. The H2 adsorption of porous carbons were studied by using PCT apparatus at moderate pressure and temperature. From the work, the H2 adsorption was observed to be markedly improved after activation. However, it was found that the total amount of adsorption was not proportion to the specific surface area of porous carbons. This result indicated that H2 adsorption could be depended on not only surface area or pore volumes but also micropore size distribution of adsorbates. |
