Abstract: Ni-based catalyst shows preferable performance in tar reforming during biomass gasification. But the deposition of carbon during the reaction can lead to the deactivation of the Ni-based catalyst. How to improve the catalytic performance and carbon deposition resistance ability of the catalyst has been the research focus. In this paper,we reviewed the recent progress on the catalytic activity and carbon deposition resistance of Ni-based catalyst from the aspects of active components,supports and promoters and discussed their influences on the performance of Ni-based catalyst. In the end,we pointed out that Ni-Fe、Ni-Co and Ni-Cu catalyst had better performance than Ni-based catalyst,and co-catalyst can help to promote the anti-carbon deposition ability and sintering resistance ability,while for the catalyst support,perovskite type mixed metal oxide,coal char and biomass char showed promising prospect.

摘要： Ni基催化剂对生物质气化过程中生成焦油的催化裂解重整具有较好的催化活性，但在催化反应中存在容易积炭进而失活的现象。如何提高Ni基催化剂的催化活性和抗积炭能力是Ni基催化剂研究中的难点。本文从催化剂的活性组分、载体和助催化剂3个方面入手，详细综述了近几年关于提高Ni基生物质焦油重整催化剂催化活性和抗积炭能力的研究进展，讨论了催化剂的活性组分、载体和助催化剂对催化剂催化活性的影响。指出Ni-Fe、Ni-Co、Ni-Cu催化剂均表现出比Ni基催化剂更好的催化活性，助剂的加入有利于提高吸附剂的抗积炭能力和抗烧结能力；催化剂载体方面，钙钛矿型混合金属氧化物载体、煤焦和生物质焦载体具有较好的研究前景。
