Description
Summary:For the separation of the CH sub(4)/CO sub(2) mixture by experiment and modeling, a novel meso-porous material, the activated mesocarbon microbeads (a-MCMBs) is used. The adsorption isotherm of nitrogen at 77 K is measured to characterize the a-MCMBs by the IGA-003 gravimetric analyzer. The adsorption experiments of pure CH sub(4) and CO sub(2) at ambient temperature of 298.15 K are carried out. A CH sub(4)/CO sub(2) mixture is prepared at the mole ratio of 85:15, corresponding to the gas composition of the Ya-13 gas field in the Qiongdongnan basin, China. Although only the total adsorption amount of the gas mixture on a-MCMBs is available, the single adsorption amount for CH sub(4) and CO sub(2), also including the selectivity of CO sub(2) over CH sub(4), can be obtained by the Zhou, Gasem and Robinson Equation of State (ZGR EOS).
