Abstract

The process of liquid-phase hydrogenation of the phenylacetylene byproduct in the industrial styrene fractions formed in different styrene manufacture stages at OAO Salavatnefteorgsintez was studied on specimens of the palladium-containing G-58E, APKGS-20E2, and KSVK catalysts. It was found that the KVSK catalyst, which is a silica glass-fiber matrix containing 0.2 wt % of dispersed palladium, was the most effective in the selective hydrogenation at atmospheric pressure and temperatures of 20–30°C of phenylacetylene present in the industrial fractions of styrene. It was shown that the minimal loss of styrene is attained in the case of phenylacetylene hydrogenation in the hydrocarbon condensate fraction.
