Reviewing the Effective Parameters on MTO Process and their Influence

In recent years the methanol to olefins (MTO) process has received wide attention as it provides an indirect route in reaching to market demand for the production of light olefins, mainly ethylene and propylene. This paper is aimed to review the effects of parameters such as, temperature, particle size, acidic strength, catalyst structure and modification made with some metals and also their effectiveness on activity and selectivity which conducts the process towards light olefins. In addition the different types of reactors and the effect of temperature, pressure and feed composition are reviewed in this process.
