An experimental approach to adsorption of CO2 + CH4 gas mixtures onto coal (European RFCS CARBOLAB research project)

Abstract : Results from adsorption experiments of CO2 + CH4 gas mixtures onto coal show that adsorption capacities determined with pure gas phases cannot be added to determine the total adsorption capacity of a gas mixture; and that both CO2 and CH4 adsorption capacities for experiments performed with gas mixtures are lower than those determined for experiments with pure gases. These results confirm that gases compete to adsorb onto coal. Results also show that the extended Langmuir model that is often used to model sorption of binary gas mixtures does not fit our experimental data. Thus, authors propose here another model.
