Abstract
The present invention provides a process for producing a vanadium/phosphorus oxide catalyst by (i) preparing a catalyst precursor powder containing vanadium, phosphorus and an optional promoter element; (ii) converting the catalyst precursor powder into an activated catalyst by heat treatment; (iii) and compressing the activated catalyst into a desired shape to form the vanadium/phosphorus oxide catalyst. The vanadium/phosphorus oxide catalyst may be used in the production of maleic anhydride by the catalytic oxidation of hydrocarbon feed streams.
