摘要:

天然气因其清洁、高效、使用方便的特点而有着其他化石能源无法比拟的优势。随着天然气需求量的增加,天然气供需矛盾也逐渐凸显,生物质合成气催化制取合成天然气成为解决天然气供需矛盾的技术之一。针对生物质合成气甲烷化过程中存在的问题,从反应过程、催化剂、反应器等方面阐述了生物质合成气甲烷化研究现状;对比了不同催化剂的催化性能,分析得出Ni基催化剂是最适合工业化的甲烷化催化剂之一。列举了国外一些固定床和流化床甲烷化反应器工业化的案例,分析了其各自的生产工艺及优缺点,得出流化床是甲烷化反应器中较为有前景的反应器,并对生物质合成气催化制取合成天然气技术的发展方向进行了展望。

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
