Method for preparing maleic anhydride catalyst

摘要

An improvement in a method of preparing catalysts for the manufacture of maleic anhydride by oxidizing a saturated hydrocarbon. The catalyst is prepared by a process in which a catalyst precursor, containing tetravalent vanadium, is formed into agglomerates and calcined, the improvement being calcining the catalyst precursor at 325 DEG -375 DEG C. in the presence of oxygen and a saturated aliphatic hydrocarbon.
