  • Process for producing vanadium chlorides
    Patent number: 4169135
    Abstract: Product yields are increased and effluent streams purified for disposal by an improved process for producing vanadium chlorides. The process comprises reacting vanadium oxide with chlorine and reactant carbon to produce substantially pure vanadium chlorides and an effluent stream containing vanadium chlorides and unreacted chlorine. The effluent stream is contacted with adsorptive carbon whereby the vanadium chlorides and chlorine are adsorbed thereon. The adsorptive carbon is subsequently recycled and used as the reactant carbon.
