金属改性ZSM-5分子筛催化剂应用于甲醇制烯烃
Advances in metal-modified ZSM-5 catalysts for methanol to olefins
摘要
Abstract
Methanol to olefins (MTO) is an important technology for the production of light olefins.ZSM-5 is one of the common zeolite catalysts for MTO/MTP.Many researchers have focused their work on the modification of ZSM-5 catalysts to improve their activity.This review has attempted to explore the relationship between the catalytic performance and the basic-acid properties,crystalline size and Si/Al molar ratios of modified ZSM-5 and to conclude the reaction scheme and the mechanism of deactivation caused by carbon deposition.Considerable efforts have been focused on reviewing the metal modifications of ZSM-5 catalysts,including the impact of alkaline earth metals,transition metals,rare earth metals,noble metals and multi-component metals on the activity,selectivity and stability of the catalyst.Finally,it is concluded that the key to develop the industrial applications of MTO is to obtain catalysts with excellent catalytic activity based on the mechanism of catalysts and their modification.关键词
