Abstract: CO2 methanation is one of the effective ways to realize resource recycling on greenhouse gas, CO2. This article was aimed to review the research progress in catalysts for catalytic CO2 hydrogenation to produce methane in the past few years. The Ni-based catalysts were widely studied in literature. The effects of Al2O3, SiO2 and La2O3 supports and CeO2, La2O3 additives on the performance of Ni-based CO2 methanation catalysts were mainly introduced, together with the effects of the structures, electronic performances and chemical properties of supports and additives on the performance of the Ni-based methanation catalysts. The Co-based CO2 methanation catalysts with ordered mesoporous structures also exhibited superior catalytic activities comparing with the studied Ni-based CO2 methanation catalysts. The results indicated that the novel structure was also a key factor to affect the catalytic performance of catalytic CO2 methanation. And CO2 methanation performance at low temperature can be improved by the modulation of catalyst structures and composition, which could lay a foundation for the industrialization of CO2 methanation process.

摘要: CO2催化加氢甲烷化反应是温室气体CO2资源化利用的有效途径之一。本文回顾了CO2催化加氢甲烷化催化剂的研究现状, 其中Ni基催化剂是研究最为广泛的CO2甲烷化催化剂。重点介绍了Al2O3、SiO2和La2O3载体及CeO2和La2O3助剂等对Ni基催化剂CO2甲烷化性能的影响, 阐述了载体的结构、电子性能、化学性能和助剂等对Ni基催化剂CO2甲烷化性能的影响。结合几种非Ni基CO2甲烷化催化剂的对比研究发现, 具有有序介孔结构的Co基催化剂也表现出了优越的CO2甲烷化性能。由此表明, 催化剂新颖的结构也是影响CO2甲烷化性能的重要因素, 通过催化剂结构、组成等的调变, 能实现CO2低温高效甲烷化, 为CO2甲烷化工业化进程奠定基础。
