Abstract: The increasing supply and demand of natural gas prompts people to search new resources of natural gas. As a result, the technology of synthetic natural gas production from biomass thermo-chemical conversion has aroused great concerns, among which the methane production from bio-syngas catalytic synthesis is one of the key steps. The latest development and research on the technology of bio-syngas catalytic methanation was summarized on the perspective of methanation reactors and catalysts, the development status of methanation catalysts was also described. The challenges of the technology of bio-syngas catalytic methanation were analyzed and the suggestions for the development were pointed out in the end.

Key words: biomass, syngas, methanation
