摘　　要：甲醇制汽油(MTG)工艺是重要的煤、天然气和生物质间接合成油技术,由于该反应过程是强放热过程,容易导致催化剂烧结和积炭,降低催化剂寿命,因此催化剂需进行原位再生处理。针对这些问题,综述了近年来对该工艺的温度控制技术和催化剂的改性、失活与再生的研究进展。Methanol to gasoline （MTG） process is an important indirect technique for conversion of coal, natural gas and biomass to liquid fuels. MTG reaction is strongly exothermic, which could easily result in the sintering, coking and lifetime shortening of catalyst, so the catalyst needs regeneration in-situ. To solve these problems, the recent advances in temperature control technology, catalyst modification, deactivation and regeneration for the MTG process were reviewed.
