| 摘要 |
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. |
