摘　　要：甲烷重整反应所用的镍基催化剂在高温下易烧结而失活,催化剂稳定性一直是研究的重点。镁铝尖晶石材料具有较好的耐高温稳定性,高温下不易烧结,因此具有良好的工业化应用前景。综述了镁铝尖晶石结构镍基催化剂的制备方法(包括分步浸渍法、共沉淀法、溶剂蒸发自组装法、溶胶-凝胶法、水热合成法和火焰喷射裂解法)及其对催化剂结构和性能的影响,介绍了镁铝尖晶石催化剂对甲烷重整反应的稳定性研究进展以及镁铝尖晶石材料与限域功能材料结合对催化剂结构及性能的影响,并对其应用前景进行了展望。The nickel based catalysts used for methane reforming are prone to sintering and deactivation at high temperatures,and catalyst stability has always been a focus of research.Magnesium aluminum spinel materials have good high-temperature stability and are not easily sintered at high temperatures,therefore they have good industrial application prospects.The preparation methods of nickel based catalysts with magnesium aluminum spinel structure(including stepwise impregnation,co-precipitation,solvent evaporation self-assembly,sol-gel method,hydrothermal synthesis and flame jet pyrolysis)and their effects on the structure and performance of the catalysts were reviewed.This article introduces the research progress on the stability of magnesium aluminum spinel catalysts for methane reforming.This article introduces the influence of the combination of magnesium aluminum spinel materials and limited functional materials on the structure and performance of catalysts,summarizes the problems existing in magnesium aluminum spinel nickel based methane reforming catalysts,and envisions their application prospects.
