Adsorption-Catalytic Deformation in the Synthesis of Hydrogenation Catalysts

It is shown that, with the help of adsorption-catalytic deformation, it is possible to significantly change the composition of the skeletal nickel hydrogenation catalyst by changing the steric factor directly under the conditions of the chemical reaction. Various substances were tested as model compounds undergoing reduction: hydrogen peroxide, sodium maleate, and propen-2-ol-1. It is shown that, during the hydrogenation reaction, as a result of strong local overheating, the catalyst grain is deformed and the aluminum atoms that were previously in the bulk of this grain appear on the surface, after which aluminum becomes available for further leaching, while yielding additional hydrogen.
