Abstract:

Methane dry reforming (DRM) is a key technology for promoting the global economy towards green and low-carbon transition, as well as for mitigating global warming. The primary challenge lies in the catalysts with high activity, stability, and superior anti-coking ability for industrial application. Currently, Ni/Al2O3 is the most widely studied non-precious metal catalyst, however issues such as sintering-induced deactivation and carbon accumulation during high-temperature reactions need to be urgently addressed. This review focuses on the research progresses over the past decade regarding the anti-coking and anti-sintering properties of Ni/Al2O3-based catalysts, and emphasis was placed on the discussion of the effects of Ni particle size, promoter modification, Al2O3 pore structure, morphology, acid-base properties, and catalyst structure type on the reactivity and stability of Ni/Al2O3-based catalysts. It is concluded that increasing the dispersion of metal Ni, the basicity of the support, the concentration of oxygen vacancy, and the porosity of the support are all beneficial to improving the catalytic activity. This article provides valuable theoretical guidance for the industrial applications of Ni/Al2O3-based catalysts in DRM reaction.

Key words: methane dry reforming, Ni/Al2O3 catalyst, stability, selectivity, deactivation, anti-coking

摘要:

甲烷干重整(DRM)是推动全球经济向绿色、低碳方向转型,缓解全球气候变暖的重要技术。开发高活性、高稳定性、抗积炭能力优异的催化剂是其工业化应用的关键挑战。Ni/Al2O3催化剂是目前研究最为广泛的非贵金属催化剂,但其在高温反应过程中因烧结和积炭导致的催化剂失活问题亟待解决。基于此,本文讨论了近十年来抗积炭、抗烧结Ni/Al2O3基催化剂开发的研究进展,重点讨论了Ni/Al2O3基催化剂中Ni颗粒尺寸、助剂改性、Al2O3孔结构、形貌、酸碱性、催化剂结构类型等因素对反应活性和稳定性的影响规律。总结发现,提高金属Ni分散度、增强载体碱性、增加氧空位浓度、提高载体孔隙率均有助于提高催化活性,为Ni/Al2O3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。
