CO2 hydrogenation activity of Ni-Mg-Al2O3 catalysts: Reaction behavior on NiAl2O4 and MgAl2O4

CO2 hydrogenation activity of nickel-magnesium-aluminum mixed oxide catalysts was investigated. As Ni concentration increased, CO2 conversion increased due to the increased active metal content and suppression of NiAl2O4 formation. Calcination temperature was found to affect the textural properties of catalysts and to decrease surface area and pore volume significantly. Therefore, catalysts calcined at a relatively low temperature showed high...
