Experimental and Kinetic Modeling Studies of Methanol Transformation to Hydrocarbons Using Zeolite-Based Catalysts: A Review
As the need for petroleum products is increasing, it has led to increased crude oil prices. For an alternative approach, much research has been done in the field of catalytic conversion of methanol-to-hydrocarbon (MTH). The MTH process is suitable, which converts methanol directly into gasoline and other valuable hydrocarbons. The review provides information about methanol to olefins (MTO), methanol to aromatics (MTA), and MTH processes involved in converting oxygenates into hydrocarbons and information regarding methanol synthesis. It reviews the effect of physicochemical properties such as acidity, pore diameter, surface area, the catalyst's lifetime, and process conditions on MTH transformation. The article shows different methods that are employed to change the zeolite's acidic properties. These methods include acidic, alkaline, and steam heat treatment, which are also discussed. The results obtained after catalytic cracking of methanol were also validated by using several kinetic models proposed worldwide.
