Synthesis of two new Nickel and CopperNickel vanadates used for propane oxidative dehydrogenation

Two new vanadates have been successfully synthesized by the hydrothermal and coprecipitation methods. Both vanadates were calcined at 600 °C and the resulting catalysts were tested on reaction of oxidative dehydrogenation of propane.

Summary:
Two new vanadates have been successfully synthesized by the hydrothermal and coprecipitation methods. Both vanadates were calcined at 600 °C and the resulting catalysts were tested on reaction of oxidative dehydrogenation of propane. The catalysts were characterized by x-ray diffraction, atomic absorption, thermogravimetric analysis, and differential temperature analysis. The reaction was carried out in the temperature range of 350-500 °C. A conversion of propane of 10.6 % and a selectivity towards propene of 29.9 % at 400 °C were obtained with nickel vanadate; a conversion of 1.9 % and a selectivity of 56.9 % were reached at the same temperature with the nickel copper vanadate.
