摘　　要：甲烷干气重整反应能够实现温室气体CO_2和CH_4的转化利用,其反应产物合成气可以通过费托反应进一步生产液态燃料,该反应在能源与环境领域具有重要意义。寻找合适的催化剂是推动甲烷干气重整工业化的关键。镍基复合结构催化剂因其与贵金属催化剂相媲美的催化活性和低廉的工业成本而受到广泛关注,但镍基催化剂存在高温下长时间反应后碳沉积和金属组分烧结所导致的失活问题,严重影响了其工业应用和干气重整化工的发展。本文从镍基复合结构催化剂的成分、结构、制备方法及模拟计算设计等方面出发,介绍了改进镍基催化剂活性、抗积碳和抗烧结性能的研究进展,并结合最新的原子催化以及原位表征等研究进展对干气重整研究的发展趋势进行展望。Methane Dry Reforming（DRM） catalysis converts the two greenhouse gases, CO2 and CH4 into syngas, which can be further utilized for liquid fuels production through Fischer-Tropsch synthesis. The DRM reaction is therefore of significance for both energy and environments. The key issue to promote industrialization of DRM reaction is to develop suitable catalysts. Nickel based composite catalysts have received extensive attention due to their outstanding catalytic activities comparable to those of precious metals and their bargain price. However, nickel based catalysts usually undergo severe deactivation due to the coke deposition and metal sintering during long-term reaction at high temperature, which seriously limit their industrial applications and development of the engineering of DRM. Many researches have been carried out to address this issue. In this review, the recent research progress in the activity, coke resistance, and sintering resistance of Ni-based composite catalysts are introduced from the aspect of catalyst components, structures, preparation methods, and simulations. The research trends of DRM catalysts are also predicted based on the recent research progress in single-atomic catalysis and the in-situ characterization techniques for catalysis.
