  • Process for the preparation of iron/lithium -promoted catalysts for the production of maleic anhydride
    Patent number: 4670415
    Abstract: Iron/lithium promoted phosphorus-vanadium-oxygen catalysts for the production of maleic anhydride are prepared by contacting a substantially tetravalent vanadium-containing compound and a phosphorus-containing compound and a promoter component containing each of iron and lithium in a substantially anhydrous alcohol medium in the presence of anhydrous hydrogen chloride to form an iron/lithium promoted phosphorus-vanadium-oxygen catalyst precursor. The catalyst precursor is recovered, dried, roasted, formed into structures if structures are desired, and calcined.
    Type: Grant
