Influence of the Method for Promoting the Со/MgAl2O4 Catalyst of Co Hydrogenation with Glucose on the Structural and Chemical Characteristics.

The effect of N-layer-by-layer promotion (N = 0, 1, 5, 10 layers) of Co/MgAl₂O₄ catalysts (MgAl₂O₄ is aluminum-magnesium spinel with S_sp = 23 m²/g) with glucose on the textural and physicochemical properties of the catalyst was studied. For Co-supported catalysts, the dispersity of cobalt increased significantly after promotion of the MgAl₂O₄ support with glucose (N > 1). For cobalt catalysts prepared by impregnation of the support with both cobalt nitrate and glucose, the dispersity of cobalt did not change. [ABSTRACT FROM AUTHOR]
