| 摘要 |
The present invention provides a process for producing a vanadium/phospho rus oxide catalyst by (i) preparing a catalyst precursor powder containing v anadium, phosphorus and an optional promoter element; (ii) converting the ca talyst precursor powder into an activated catalyst by heat treatment; (iii) and compressing the activated catalyst into a desired shape to form the vana dium/phosphorus oxide catalyst. The vanadium/phosphorus oxide catalyst may b e used in the production of maleic anhydride by the catalytic oxidation of h ydrocarbon feed streams.
