Abstract:

Natural gas is becoming more and more advantageous than other kinds of fossil energy because it is clean, efficient and convenient to use. With the increasing demand of natural gas, the conflict between supply and demand of natural gas has gradually become increasingly prominent. The catalytic synthesis of synthetic natural gas from biomass synthesis gas has become one of the major technologies to solve the conflict.In allusion to the methanation of biomass synthesis gas, the research status of biomass synthesis gas methanation was explained from the aspects such as reaction process, catalyst and the reactor. Through comparing with the catalytic performance of different catalysts, it was analyzed that Ni-based catalyst was the most suitable for methanation catalyst for industrialization. Some cases of fixed and fluidized bed industrialization from abroad were showed and analyzed their production processes, advantages and disadvantages, it proved that the fluidized bed was very promising in the methanation reactor. Finally, the orientation of developing of biosynthesis gas catalytic synthesis of synthetic natural gas technology was outlooked.

Key words: synthetic natural gas, reactor, catalyst
