The physisorption properties of CH4 in MOR and MFI zeolites are studied using the grand canonical Monte Carlo method. Some important physical quantities are obtained, such as adsorption amounts, isosteric heats, interaction energies of zeolite, CH4 molecules, etc. The results show that the physisorption properties of MOR zeolite are superior to those of MFI zeolite in all conditions. The reasons causing such different results between them are analyzed from the interaction energies between zeolites and CH4 molecules, the relationships between isosteric heats and adsorption amounts, etc. |
