Various types of catalysts are used in different stages of the MTG process. Zeolite catalysts, particularly ZSM-5, are widely used due to their high selectivity and stability. Zeolites are microporous, allowing them to selectively catalyze the formation of specific hydrocarbons while minimizing undesired side reactions. Other catalysts such as metal oxides and acid catalysts are also employed in the initial methanol dehydration step.
