Abstract

The review summarizes various approaches to the description of the olefins synthesis kinetics from methanol/dimethyl ether for two types of zeolite catalyst, ZSM-5 and SAPO-34. It has been shown that along with phenomenological models, microkinetic models derived with taking account of the detailed reaction mechanism and quantum-chemical calculations based on the single-event concept of the reaction rate and the transition state theory are being widely used now. Both power laws and the Hougen—Watson equations are proposed to describe the rates of elementary steps.
