Benzene Oxidation Method
Maleic anhydride production via the benzene method occurs in a fixed-bed reactor: benzene feedstock reacts with air under the catalysis of V-MO-P silica-supported catalysts to generate maleic anhydride gas. The gas is then absorbed by water, followed by constant-pressure dehydration and vacuum distillation to obtain maleic anhydride. In this process, the overall technology is optimized by adjusting catalyst loading, reactor pressure, inlet air temperature, space velocity, and molten salt temperature.
