Adsorption of Some Aromatic Compounds in ITQ-1 Zeolite: Grand Canonical Monte Carlo Simulations
摘要
Abstract
The sdsorption behavior of benzene, toluene and m-xylene in ITQ-1 zeolite has been studied by using grand canonical Monte Carlo (GCMC) simulations. The mass clouds of the studied sorbate molecules indicate that the diffusion and adsorption of sorbate molecules mainly occur in 12-MW cavities, while the diffusion and migration in 10-MR channels seem to be more difficult. A series of calculations have been performed to predict the adsorption isotherms of those molecules at 315 K and 0—1.4 kPa, and the results coincide well with the results from experiments of a series of aromatic compounds. The GCMC simulations and experimental results reveal that at a certain pressure and temperature, all the studied molecules can migrate through 10-MR channels and 10-MR windows systems interconnecting 12-MR supercages and reach the adsorption equilibrium.关键词
