Claim:
1. A titanium tetrachloride purification process comprising the steps of: a) contacting an adsorbent with a feedstock comprising titanium tetrachloride and at least one impurity, wherein at least a portion of the at least one impurity is adsorbed on the adsorbent to thereby form a product stream having a reduced amount of the at least one impurity, wherein said at least one impurity comprises a compound selected from the group consisting of carbonyl sulfide, sulfur dioxide, phosgene, hydrogen sulfide, carbon disulfide, and chlorides and oxychlorides of: post transition metals, metalloids, zirconium, hafnium, iron, chromium, copper, carbon, manganese, vanadium, nickel, thorium, uranium; and combinations thereof, and wherein the adsorbent comprises a faujasite zeolite having an average channel size in the range of from about 6.5 Å to about 7.5 Å and selected for the removal of the at least one impurity based on: i) the geometric size of the at least one impurity, and ii) the channel size of the faujasite zeolite; and b) withdrawing said product stream from said adsorbent having said at least one impurity adsorbed thereon.
