摘要
Abstract
Copper-based ZSM-5 zeolite catalysts were prepared using different ways of drying, the microwave drying and the conventional way, that is, electric blasting drying, based on incipient wetness impregnation method.XRD and N2 physisorption techniques were employed to investigate the effect of drying method on porous structure, phase structure as well as catalytic activity.The results show that copper introduction significantly promotes the catalytic activity;below 200 ℃ the catalytic activity of the microwave-dried M-4Cu-ZSM-5 is slightly higher than the conventionally-dried 4Cu-ZSM-5, while between 200-300 ℃ the latter exhibites superior catalytic performance;porous structure, crystal size and distribution of the active species of the catalyst were directly affected by the microwave treatment, causing the differences in catalytic activity.关键词
