Advances in mechanism and kinetics for MTO reaction

As an important non-petroleum route for light olefin production,Methanol-to-Olefin(MTO) technology has been paid much attention to.However,its reaction mechanism,especially the path for formation of the first C—C bond,has long been discussed by researchers.Recently,the Hydrocarbon Pool parallel reaction mechanism has been gradually accepted.On this basis,many reports concerning MTO reaction kinetics have been published.Researches in coke formation and deactivation kinetics over SAPO-34 catalysts were reviewed in this paper.Detailed reviews were given to reaction mechanism,kinetics,coke formation and deactivation kinetics for MTO reaction over SAPO-34 zeolite catalyst.
