EXTRACTING VANADIUM FROM DEACTIVATED CATALYSTS |
摘要 |
A process for recovering vanadium from a deactivated catalyst, in which process a catalyst which has become deactivated in the catalytic hydrotreatment of a vanadium-containing hydrocarbon oil is treated with steam under specified conditions followed by extraction with an aqueous solution of a mineral acid, after which vanadium is isolated from the vanadium-containing solution thus obtained. |
