Activation of heterogeneous catalysts by organoaluminium compounds

The catalytic (benzene hydrogenation) and adsorption (O2, CO) properties of NiO/Al2O3 and Ni(C5H7O2)2/Al2O3 reduced by trimethylaluminium and hydrogen have been studied. Significant differences in their catalytic and adsorption properties have been observed. The increased hydrogenation activity of catalysts reduced by trimethylaluminium is due to the increased reduction degree and dispersity of the active component.
