Liquid-phase hydrogenation of 1-hexene and phenylacetylene over multicomponent nickel skeleton catalysts

This paper presents the results of a study process hydrogenation 1-hexene in ethanol and phenylacetylene hexanewater suspension over multicomponent nickel skeleton catalysts It was demonstrated that activity is substantially dependent on nature additives introduced into bearing alloy. Introduction Cu, Pb Ta leads to an increase (W=196-295cm 3 /min-gNi). The major mechanism effect emulsion composition rate selectivity involves change coefficient distribution substances between solution surface catalyst. also shown presence water, which competes with unsaturated hydrocarbons during adsorption, adversely affects purification from acetylenic hydrocarbons, as well stereo-regular polymerization monomer. research kinetics direction processes suggest significant adsorption factor, including ratio free energies, concentrations spatial orientation molecules mixture components, interaction reacting hydrogen thecatalyst surface.
