利用煤基甲醇合成油是我国近年引进的重点技术产业，煤基合成油工程造气工艺技术改造项目采用先进的 HT-L 粉煤加压气化技术生产甲醇合成所需精制气，以煤为生产原料，现有甲醇合成装置的原料气，以生产甲醇，进而生产合成油。该项目利用“三高”劣质煤由甲醇合成汽油（MTG）的煤制油示范工程，不但可解决“三高”劣质煤出路，还可开辟石油生产新技术，可使得我国石油资源的匮乏得到缓解。“,”using coal based methanol to synthesize oil is a key technology industry introduced in China in recent years. In the project of technological transformation of gas making process of coal based synthetic oil project, the advanced ht-l pulverized coal pressurized gasification technology is used to produce refined gas for methanol synthesis. Coal is used as raw material, and the feed gas of existing methanol synthesis plant is used to produce methanol and then synthetic oil. The demonstration project of using “three high” inferior coal to make oil from methanol to gasoline (MTG) can not only solve the problem of “three high” inferior coal, but also open up new technology of oil production, which can alleviate the shortage of oil resources in China.
