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 MoV0.3 catalyst prepared by a hydrothermal method exhibited the best catalytic behavior. Using this catalyst 10.7 per cent selectivity to methacrolein and 15.3 per cent selectivity to methacrylic acid can be achieved at an isobutane conversion of 10.4 per cent at 380 graduate C.
