VANADIUM PHOSPHORUS OXIDE CATALYST AND AEROSOL METHOD OF PREPARATION

摘要

A novel vanadium phosphorus oxide (VPO) catalyst obtained using a novel VPO preparation technique. The VPO composition is characterized by the powder x-ray diffraction pattern given in Table 1. The novel VPO preparation technique consists of 1) dissolving vanadium and phosphorus compositions in a solvent such as water to form a solution, 2) forming an aerosol from the resulting solution, 3) heating the aerosol to afford a VPO precursor, and 4) activating the VPO precursor to give the VPO catalyst. The activated VPO catalyst demonstrates selective oxidation activity for hydrocarbons and good conversion and selectivity for the oxidation of butane to maleic anhydride.
