Oxidative dehydrogenation of propane to propene in the presence of H2S at short contact times

The oxidative dehydrogenation of propane to propene at short contact times over V₂O₅/A1₂O₃ was remarkably enhanced by the introduction of H₂S in the feed mixture. Overall conversion of propane over this catalyst at 700 °C and 5 ms contact time was 53.7% with selectivity to propene of 56.5%, providing a net propene yield of 30.4%.
