HYDROPOLYMERIZATION OF ACETYLENE OVER PALLADIUM CATALYST IN FIXED BED PART I: EFFECT OF DIFFERENT VARIABLES ON THE PATTERN OF ACETYLENE CONVERSION

Abstract

The puttern of acetylene conversion in the hydropolymerization reaction over palladium catalyst in fixed bed has been studied and  the effects of varying the palladium concentration and of incorporating ZnO-Cr2O3 additve in the catalyst have been determined The effect of feed dilution with inert nirgen on the conversion pnitern hus been studied. Conversion data on the hydropolymentsation  reaction carried over Pd-ZnO-Cr2O3 Kieselguhr (0 02 : 5.0 : 4.6 : 100) catalyest have been Processed  in respect qf reaction temperature space velocity and feed gas composition as variables. Results lead to the conclusions conclusions that acctylene conversion to ethylene, butarliene, and oil are primrury reactions, while butenes are secondary products stenning from primarily proriured buiadiene.
