Abstract: Methanation is a well developed commercialized process of hydrogen purification，which converts residual CO and CO2，the poisons to subsequent processes back to methane using a small fraction of the hydrogen gas. This paper introduces the research progress of the representative catalysts，especially Ni catalysts for methanation reaction in recent years，and introduces the effects of promoter，support and preparation method on the performance of catalyst. The mechanisms of CO and CO2 methanation on different catalysts are also presented.
