煤制天然气中甲烷化工艺技术进展及比较

The Process Technology's Progress and Comparison of Methanationin Coal-based Substitute Natural Gas

甲烷化合成技术是煤制天然气的关键技术.介绍了国内外甲烷化技术的概况,对国外Lurgi、TREMP、Davy 3种甲烷化工艺及催化剂进行比较,并对国内的甲烷化技术目前发展情况进行了介绍.

The technology of methanation synthesis is the key in the system of coal - based substitute naturalgas. The situation of the methanation synthesis technology at home and abroad was intruduced, and three kinds ofmethanation processes and catalyst of Lurgi, TREMP and Davy were compared. The situation of progress ofmethanation technology in our country was intruduced.
