A new method has been developed for the reduction of silica-supported nickel chloride. The rate of reduction depends on the reducing agent (hydrazine) and alkali concentration, temperature and the order of mixing of the reactants. Chalk additions have a promoting effect. A study has been made of the properties of the synthesized catalyst in the decomposition of hydrazine and the hydrogenation of unsatured hydrocarbons. The dependence of catalytic activity on the hydrazine/nickel ratio, the nature of the alcohol and temperature has been found.
