Maleic anhydride process |
摘要 |
A process is provided for the preparation of attrition resistant, microspheroidal fluid bed catalysts comprising the mixed oxides of vanadium and phosphorus in which a vanadium phosphorus mixed oxided catalyst precursor is densified, comminuted, formed into fluidizable particles and calcined under fluidization-type conditions. The present invention further provides the attrition resistant fluidizable catalysts prepared by the inventive process, and further provides a process for utilizing such attrition resistant catalysts in the production of maleic anhydride in the vapor phase by the oxidation of 4 carbon atom hydrocarbons.
