A study was conducted to prepare activated carbon from ZnCl2-treated oil palm kernel shell using the sequential combination of carbon dioxide and steam (CO2 + steam) as activated agent. The development of pores of activated carbon and methane adsorption on the prepared activated carbon were investigated. The results show that the sequential combination of CO2 and steam was a good combination producing activated carbon with high total pore volume of 1.0 cm3/g and BET surface area of 1548.0 m2/g. The resultant activated carbon contained microporous and mesoporous structure with a nearly balance volume percentage. The highest methane uptake in this study was 145.89 V/V at 10 bar and ambient temperature. © 2016, Malaysian Society of Analytical Sciences. All rights reserved.
