Abstract

A method for recovering vanadium from a spent slurry catalyst for hydrocarbon oil hydroprocessing is disclosed. In one embodiment after de oiling the spent catalyst is treated with ammonia and air forming a leach slurry. The leach slurry is subsequently treated with a flocculant. After solid liquid separation to recover the solid residue containing coke and ammonium metavanadate the solid residue is washed with an ammonium sulfate solution and leached with hot water. After solid liquid separation to recover a solution containing ammonium metavanadate the ammonium metavanadate is crystallized and purified from the leach solution.
