Selective conversion of ethylene to propylene over rhenium-containing heterogeneous catalysts

The development of new technologies for effective propylene production is a highly important scientific and industrial task nowadays. In this study, the conversion of ethylene to propylene (ETP reaction) was explored over rhenium-containing catalysts supported on a ZrO 2 carrier at temperatures 100°C–200°C and atmospheric pressure using a flow catalytic reactor with a fixed catalyst bed without the use of any other hydrocarbons or dilutants. The effect of rhenium presence in the catalysts on the activity and propylene selectivity was examined.
