The influence of temperature to the propane catalyst
Mo-V-Te-Zr
Abstract: In this paper (NH4)6Mo7O24•4H2O、NH4VO3、H2TeO4•2H2O as the main raw material, and add Zr(NO3)4 ·5H2O under hydrothermal synthesis、microwave method and coprecipitation method to make the catalyst former , dry Roasting through programmed activation Preparation of the composite oxides Mo-V-Te- Zr catalyst. By relying on the gas-solid phase micro-reactor and gas chromatography combined with the right catalyst samples of activity eva luation. By BET, XRD characterization of the catalyst surface area than the crystalline phase and carried out an inspection. The experimental results show that: different hydration temperature, the drying and the reaction temperature on the catalyst surface area, phase and activity. coprecipitation method A1 the reaction temperature of 500℃, to be the largest propane conversion, for the 25.6%; Acrolein the highest yield is 16.8%, the yield of acrylic is not so satisfied.
