Abstract: In this paper MoO3, VOSO4H2O and TeO2 as the main raw material, and add CeO2. at different temperatures under hydrothermal synthesis, and the combination of microwave and conventional heat drying and dry Roasting through programmed activation Preparation of the composite oxides Mo-V-Te-0x 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. Microwave heating of the catalyst increases the surface area, and change the phase catalyst. Microwave drying under the hydration temperature of 190℃ the reaction temperature of 450℃, to be the largest propane conversion, for the 36.41%; Acrolein the highest yield is 14.75%, the yield is acrylic 5.59%.
