Improved process for producing vanadium chlorides.

摘要

An improved process for the production of vanadium chlorides is provided wherein vanadium oxide is reacted with chlorine and reactant carbon to produce substantially pure vanadium chlorides and an effluent stream containing vanadium chlorides and unreacted chlorine and the effluent stream is contacted with adsorptive carbon to adsorb the vanadium chlorides and chlorine in the effluent and the adsorptive carbon containing the adsorbed vanadium chlorides and chlorine is recycled as reactant carbon.
<??>In the process vanadium oxide and chlorine are fed to a reactor (22) containing reactant carbon in fluidized form. The reaction mixture is fed via a cyclone (34) first to a condensers (36) and (40). The gaseous material from condenser (40) forms a part of an effluent stream (66). The effluent stream (66) is passed through an adsorber (68) containing adsorptive carbon. The adsorptive carbon having adsorbed therein vanadium chlorides and chlorine is passed to a storage area (78) where it is mixed with make up reactant carbon and recycled as reactant carbon.
