摘要：

A series of boron isomorphously framework-substituted ZSM-5 (B-x-Al-ZSM-5, Si/Al = 200, B/Al = X) were synthesized and used to selectively transform methanol to propylene (MTP). The catalytic stability can be significantly influenced by B incorporation. In comparison with the conventional ZSM-5, the B-1-Al-ZSM-5 catalyst afforded a 7-time-long catalytic life under a space velocity of WHSV 1.8 h(-1) (700 h for B-1-Al-ZSM-5 and 100 h for ZSM-5, respectively). The enhancement of catalytic stability can be attributed to the increase of weak acid sites on the ZSM-5 catalysts. (C) 2012 Elsevier B.V. All rights reserved.
