Dissolving petroleum coke in molten iron to recover vanadium metal |
摘要 |
A process for the recovery of vanadium from a petroleum coke or heavy hydrocarbon feed comprising dissolving the feed in a molten metal bath to which oxygen containing gas is added to maintain heat balance and bum off carbon. Preferably the feed is added via a high pressure nozzle as a coke/steam mixture discharged down into a molten metal bath. Preferably the net gas make from the molten metal reactor is quenched and/or cooled to permit dust recovery, with recycle of dust to the molten metal reactor. An iron/vanadium product is withdrawn from the molten metal reactor as a product.
