Nanostructured Hydrotalcite-Supported RuBaK Catalyst for Direct Conversion of Ethylene to Propylene

详细

A novel nanostructured hydrotalcite-supported alkali-doped ruthenium-based catalyst is introduced for the direct gas-phase conversion of ethylene to propylene at 70°C and 1 atm. The maximum conversion of ca. 87% was obtained at the initial time on stream with a 65% selectivity to propylene and a 6% selectivity to butenes via consecutive reactions. Both conversion and selectivity to olefinic products decreased after 24 min of operation, however.
