Preparation of Mo-V Catalysts for Selective Oxidation of Isobutane

A series of Mo-V-O catalysts for the selective oxidation of isobutane were prepared by a hydrothermal method and by a solution reaction. The synthesis method, catalyst composition and calcination temperature have great effect on the catalytic behavior. Catalytic tests showed that Mo V 0 . 3 catalyst prepared by a hydrothermal method exhibited the best catalytic behavior. Using this catalyst 10.7% selectivity to methacrolein and 15.3% selectivity to methacrylic acid can be achieved at an isobutane conversion of 10.4% at 380°C.
