Abstract

Vanadium is recovered from a catalyst or contact material contaminated with carbon and vanadium by heating in an oxygen-containing gas at a temperature sufficient to burn off the carbon but insufficient to volatilize the vanadium, and then increasing the temperature to volatilize the vanadium as oxide. Bauxite which has been used for the removal of vanadium from petroleum products as described in Specifications 729,301 and 729,303 is first heated to approximately 1000 DEG F. in a mixture of air and an inert gas, e.g. nitrogen, and then heated in air alone to approximately 1300 DEG F. Vanadium oxide is recovered in an air-cooled condenser. When the catalyst is in the form of a moving bed, the air used in the second stage passes in countercurrent.
