It is currently attracting attention in line with the global trend of carbon-neutral policies. In the Ni-based catalysts, the addition of Mg metal promoter was known as high catalytic stability because of enhanced resistance on coke formation. Furthermore, it can also affect the surface acidity-basicity of Ni-based catalysts. By forming a spinel structure of MgAl2O4, properties like thermal stability and surface acidity-basicity can be changed. And it affects the catalyst activity and low coke formation as well. In this study, MgAl2O4 support was manufactured by the solid-state method. Following that, Ni/MgAl2O4 catalysts were prepared by the incipient wetness impregnation method with various Mg/Al ratios. The prepared catalysts were characterized by N2 physical adsorption, H2-TPR, TGA, and XRD. The catalytic reaction was performed in a fixed bed reactor with a Steam/Carbon ratio of 2 under 750~850 oC, 10,000 h-1 of GHSV, and 1 bar.
