  • Carbon dioxide (CO2) methanation (Sabatier reaction) is one of the key techniques of air quality management in the manned space Environmental Control and Life Support System (ECLSS). Meanwhile, the same carbon dioxide methanation technology is also used in coal chemical industry. The carbon dioxide methanation reaction mainly occurs at the last stage of coke oven gas methanation process and coal-to-substitute natural gas methanation process, using carbon dioxide methanation catalyst. Great progress has been made in China's industrial methanation technology in recent years. The technology for industrial high purity carbon dioxide maybe helpful for the research of Sabatier technology used in spacecraft. In view of the latest development of industrial methanation technology, the Sabatier reaction and the industrial carbon dioxide methanation technology are summarized and compared, from three aspects including CO2 methanation process, catalyst and reactor, and suggestions for the research of Sabatier technology in manned spacecraft are given.
