The effect of previous gamma irradiation of support is studied for a hydrogenation nickel catalyst prepared by depositing the active component on kieselguhr; the rate and degree of calcination, degree of reduction, and surface area of the samples and the rates of heterogeneously catalyzed hydrogenations of maleic acid and sunflower oil are determined. The effect of the reduction temperature on the catalyst activity is examined in detail; due to interaction with hydrogen, two activity values are obtained for a given temperature.
