Process for regenerating and stabilizing phosphorus-vanadium-oxygen complex catalysts |
| abstract |
The present invention relates to a process for the regeneration and stabilization of certain phosphorus-vanadium-oxygen complex catalysts or phosphorus-vanadium-oxygen co-metal complex catalysts, with halogen-containing components and subsequently treating the catalyst with phosphorus compounds. These catalysts are useful for the manufacture of maleic anhydride from butane feedstock. |
