Influence of the Method for Promoting the Со/MgAl 2 O 4 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/MgAl 2 O 4 catalysts (MgAl 2 O 4 is aluminum-magnesium spinel with S sp = 23 m 2 /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 MgAl 2 O 4 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.
