摘要:The activity of FCC additives of Zn(Al2O)2 with different ZnO contents were prepared by solgel,and the desulfurization effect of additives in the gasoline was evaluated in a micro reactor.The results indicate that the additive with 10% ZnO shows the best desulfurization activity,the conversion of thiophene reaches 12.7%.The activity of the additives with CeO2 was also studied,which can remove 18.13% thiophene from gasoline in the micro reactor.The crystals and acidic of additives were studied by XRD and Infrared Ray.IR results show that weak Lewis acid amounts affected activity of the additives.XRD results indicate that the best crystal of Zn(Al2O)2 spinel is not in favor of removal of thiophene.When the crystallinity is low,there are more active sites with more adsorption activity.The additives show the better desulfurization effects when the adsorption sites and L acid sites reach balance.
