Abstract

The addition of K2O, Cr2O3, Sm2O3 or Nb2O5 to V−Mg−O catalyst decreased both activity and selectivity in propane oxydehydrogenation. By comparing these results with the characterization data, a relationship between propylene selectivity and catalyst reducibility was revealed. The most easily reduced catalyst was the most selective.
