Notes:
In this study, methane gas absorption ability of activated carbon (AC) with surfacefunctional group effect, was evaluated after nitric acid and urea treatment of AC surface. Specificsurface area and pore distribution of AC were studied through nitrogen absorption isotherm at 77 K.Micro pore volume was calculated through H-K method. Absorbed methane amount was evaluatedthrough volumetric method at room temperature by using auto absorption apparatus. Absorbedmethane amount of AC was found to increase with specific surface area increase. Correlationproposed between the methane absorption amount and surface nature indicates that the surfacenature plays an important role on the absorption amount at a given temperature
