Abstract: | With the improvement of people’s living standards and rapid industrial growth,the demand for natural gas has become increasingly greater and the supply can not meet the demand for natural gas for a long time. Coal-based synthetic natural gas production consists of coal gasification,shift reaction,purification and methanation of synthetic gas. More attention is paid on high temperature methanation catalyst development. In this paper,firstly,the status and progress of high temperature methanation catalyst development in China and overseas are introduced,and the composition and deactivation of catalyst are discussed. Deactivation is mainly caused by sulfur poisoning,sintering and carbon deposition. The research direction of high temperature methanation catalyst is presented. |
