PROCESS FOR PURIFYING TITANIUM TETRAHALIDES OR ZIRCONIUM TETRAHALIDES

Patent ·
OSTI ID:4270378
A fluidized bed process for purifying ZrCl/sub 4/ or TiCl/sub 4/ is presented. The halide vapor from the halogenation step is passed directly through a fluidized bed of metal or metal-coated particles where impurities such as V react with the metal. The fluidized bed may consist of Cu, Zn, Fe, Ni, Ca, Mg, Al, Ti, Pb, Sb, Sn, or Na particles. A three-zone proeess is described in which two zones are being fluidized and used while the third zone is being recharged with metal powder. (T.R.H.)
