Open publisher page 2 citations

Abstract

Abstract The technique of using mixtures of H2S/O2 and H2S/SO2 to selectively dehydrogenate hydrocarbons in the presence of suitable catalysts has been applied to the production of styrene from ethylbenzene. The mechanism of the reaction is discussed and results are presented on the influence of different catalysts and the optimization of processing variables such as temperature, space velocity and reactant concentrations. Styrene yields as high as 75% have been achieved under optimum conditions.
