摘要
Abstract
A ZSM-5 zeolite with the particle sizes of about 400nm~1μm was synthesized from macroporous silica gel by hy-drothermal crystallization, named as zeolite A, which was treated with steam to obtain zeolite B. The structural properties of both zeo-lites A and B were characterized by SEM, XRD, NH3-TPD and nitrogen adsorption, and their catalytic performances for methanol to propylene (MTP) reaction were comparatively investigated. Results show that steam treatment caused a decrease in the strength and amount of acidic sites and an increase in pore volume and average pore width. As a result, the propylene selectivity and life time of the catalyst were significantly improved.关键词
