Equilibrium data for the adsorption of hydrogen, carbon dioxide, and binary mixture of both gases on activated carbon were determined experimentally. Pure component isotherms were presented along with pressures up to 30 atm at 301 K, 323 K and 348k. Also, the binary equilibria were obtained at various temperatures same above for pressure of 1.5, 10 and 20 atm, respectively. For the pure component system, Freundlich isotherm was shown to be fitted best to the experimental results. However, in the binary system, the ideal adsorption solution(IAS) theory gave good representation of the binary experimental data in high pressure range.
