Computer Simulation of the Adsorption of Thiophene in All-Silica Y and Na−Y

Abstract: A grand canonical ensemble Monte Carlo simulation is performed to investigate the adsorption, heat of adsorption, and distributions of thiophene in all-silica Y and Na-Y zeolites. Biased particle insertions and deletions were implemented to allow the computation of equilibrium adsorption isotherms of such molecules. The calculated number of absorbed thiophene molecules in these zeolites is in good agreement with the experimental data. The calculated results show that the number absorbed of thiophene molecules … Show more

“…Conversely, DES 5 was the most affecting agent among the DESs, and five new peaks were detected after treatment, all of which corresponded to peaks in the DES spectrum. The bands between 3326-3186 cm-1 represented −NH2 and −NH− stretching vibrations, whereas the in-plane stretching of -NH was evident at ~1605 cm-1 [44,45]. New detected peaks in FTIR spectra of some graphene samples after DES treatment with the expected matching functional groups Given the above observations, it is apparent that at any rate, the treatment of graphene with KMnO4 accounted for the changes in the functional groups obtained from DES on the carbon surface.…”
