Abstract：Methanol conversion reactions could be divided into three broad types: methanol-to-olefins (MTO), methanol-to-gasoline (MTG) and methanol-to-aromatics (MTA) reactions. Microporous molecular sieves were generally used as commercial catalysts in methanol conversion for their high hydrothermal stability and good shape selectivity, but the deactivation of catalysts was the main problem for industrial application. In this paper, research status of SAPO-34 and ZSM-5 catalysts for MTO reaction and ZSM-5 catalyst for MTG and MTA reactions, effects of hydrocarbon pool mechanism in methanol conversion reactions, and deactivation reasons of the catalysts were reviewed. In addition, industrialization developments of MTO, MTG and MTA reactions were summarized. MTO reaction was right at the rapid development period for its early start. MTG reaction was currently in the industrial promotion stage, but the scales were relatively small. MTA reaction was started relatively late in China, and some breakthroughs were made in recent years.
