IMMOBILISATION OF VANADIUM DEPOSITED ON CATALYTIC MATERIALS DURING THE CONVERSION OF OIL THAT CONTAINS HEAVY METALS AND COKE PRECURSORS |
摘要 |
A process is disclosed for catalytic cracking a hydrocarbon oil feed having a significant vanadium content to produce lighter products. The catalyst, from the cracking step, coated with coke and vanadium in an oxidation state less than +5, is regenerated in the presence of an oxygen-containing gas at a temperature high enough to burn off a portion of the coke under conditions keeping the vanadium in an oxidation state less than +5. |
