Research progress on magnesium aluminum spinel nickel based catalysts for dry reforming of methane
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 evapora-tion 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.
