Resumo

New nickel-containing catalysts based on the phyllosilicate phase have been obtained by microwave activation for efficient liquid-phase hydrogenation of a number of unsaturated compounds to olefins under relatively mild reaction conditions: T = 100–140°C, pH2 = 1.5 MPa, reaction time 1 h. A comparison of the synthesis methods showed that the best results with 90.1% selectivity of styrene formation at 89.6% conversion of phenylacetylene were obtained on the nickel catalyst prepared by microwave synthesis.
