Ga2O3/HZSM-48 for dehydrogenation of propane: Effect of acidity and pore geometry of support
E-mail:
The catalytic performance of propane dehydrogenation over HZSM-48 supported Ga2O3 catalysts in the presence of CO2 was investigated, and compared with that of HZSM-5 supported ones. The activity decreases with the increase of Si/Al ratio of catalyst support while the selectivity to propene shows a contrary trend. Ga2O3/HZSM-48 with Si/Al ratio of 130 has the best propene yield of 22%. HZSM-48 supported catalysts exhibit higher selectivities to propene than the HZSM-5 supported ones at similar propane conversion, due to their weak acid strength. However, their stabilities are not so good as those of the latters, owing to their more weak acid sites and unidimensional pore structures.
