One unsupported nickel catalysts (about 55 wt.% Ni) supported on SiO2, Al2O3, TiO2, Nb2O5, ZrO2, V2O5 and ZnO were characterized by pulse dynamic oxygen chemisorption measured at -78 °C and evaluated in the reaction of reductive amination of diethylene glycol. Correlation was obtained between their oxygen uptake and catalytic activity.

The effect of HZSM-5, H-silicalite and amorphous silica admixtures on the surface properties of nickel catalysts as well as on their activities, selectivities and stabilities in the reductive amination of diethylene glycol was studied. It was found that, in comparison with amorphous silica, zeolites do not positively affect the catalytic properties of nickel catalysts. In addition, the acidity of the zeolites, the dispersity of the nickel phase, changes in the chemical composition during the reaction and adsorption of the reaction components or intermediates on the surface and consequent blocking of the zeolite surface played a role.
