Abstract: This paper introduces Mo-V-Te based catalysts, and the performancet of catalyst prepared by different methods. Hydrothermal synthesis temperature of the catalyst less affected among the experimental temperature range. The reaction temperature of the catalyst is obvious that 450 ℃ catalytic effect is the best. Microwave drying and conventional drying of the propane conversion rate will be affected, but not very different. Conventional drying can be a catalyst for the high selectivity of acrolein, Microwave drying acrylic rules of the greater selectivity and inhibition of COX-product formation. With auxiliary Ce content increasing, propane conversion and the selectivity of acrylic significantly improved, However, the selectivity of acrolein has decreased. Surface area and crystalline structure of the catalyst were characterized by methods of BET and XRD. In the synthesis catalyst, the specific surface area generally low. Catalyst crystalline structure to MoO3 mainly, but the addition of Ce catalyst, Catalyst conducted in the microwave drying, the catalyst this time the emergence of a new phase.
