摘　　要：甲烷干重整(DRM)利用CO_(2)和CH_(4)两种温室气体生产合成气,在科学研究和工业应用领域都受到广泛的关注。Ni基催化剂是应用最广泛的非贵金属催化剂,但在高温反应过程中会产生积碳导致催化剂失活,影响了其工业化应用。对Ni基催化剂在DRM反应过程中的失活过程,尤其是对积碳机理及抗积碳的方法进行了综述,分析了DRM过程中Ni基催化剂中不同组分间的相互作用,阐述了Ni基催化剂中活性金属、载体和助催化剂等组分间的相互作用对DRM反应中催化剂积碳的影响。通过分析DRM反应在Ni基催化剂上的反应途径、催化活性及反应过程中的积碳情况,发现活性金属、载体和助催化剂等组分间的相互作用不仅改善了Ni基催化剂的DRM反应性能,并可利用各组分的相互作用,设计出具有抗积碳性能的Ni基催化剂。抗积碳催化剂的研究为Ni基催化剂在DRM反应中的工业化应用提供了一定的理论指导和研究依据。Dry reforming of methane(DRM),which produces syngas from two greenhouse gases CO_(2) and CH_(4),has been widely concerned in both scientific research and industrial application fields.Ni-based catalysts are the most widely used non-noble metal catalysts.However,carbon deposition will occur in high-temperature reactions,resulting in catalyst deactivation,which affects its industrial application.The inactivation process of Ni-based catalysts in the process of DRM,especially the mechanism of carbon deposition and the anti-carbon deposition methods were reviewed.The interactions among different components of Ni-based catalysts in DRM were analyzed,and the effects of the interactions among the active metal,support and co-catalyst components on the carbon deposition of the catalyst in the DRM reaction was discussed.By studying the reaction pathway,catalytic activity,and carbon deposition during the DRM reaction on Ni-based catalysts,it is found that the interaction between the active metal,support and co-catalyst components not only improved the DRM reaction performance of Ni-based catalyst,but also designed a Ni-based catalyst with anti-carbon deposition performance by using the interaction of each component.The study of anti-carbon catalyst provides theoretical guidance and research basis for the industrial application of Ni based catalyst in DRM reaction.
