  • Patent number: 5585078
    Abstract: In a process for chlorinating titanium containing material in a fluidized bed reactor which evolves gaseous material including CO, COS, and TiCl.sub.4, the improvement comprising introducing oxygen containing gas at a location or locations which are downstream of the surface of the bed, as measured in its static condition, to convert at least some CO to CO.sub.2 and some COS to CO.sub.2 and SO.sub.2.
    Type: Grant
    Filed: November 21, 1994
    Date of Patent: December 17, 1996
    Assignee: E. I. Du Pont de Nemours and Company
    Inventors: Paul G. Reis, Melvyn B. Pell, David N. Low, Hans H. Glaeser
  • Patent number: 5389353
    Abstract: In a fluidized bed process for chlorinating rirnium-containing material, an improvement is disclosed comprising utilizing in the process calcined petroleum shot coke, calcined petroleum fluid coke or mixtures thereof. The improved process is capable of (a) decreasing the amount of fine particulate coke that is entrained in the hot gases exiting the fluidized bed reactor, and (b) more completely reacting the coke.
    Type: Grant

    Inventors: Hans H. Glaeser, Mark J. Spoon
  • Patent number: 4214913
    Abstract: A process for preparing rutile TiO.sub.2 by a process comprising oxidizing with oxygen or an oxygen containing gas, a mixture TiCl.sub.4 and AlCl.sub.3 and after at least 80% of the TiCl.sub.4 has been converted to TiO.sub.2 adding sufficient PCl.sub.3 to form from 0.1-0.5% P.sub.2 O.sub.5 in the TiO.sub.2, the amount of AlCl.sub.3 being sufficient to form 0.1-1.5% Al.sub.2 O.sub.3 in the TiO.sub.2.
    Type: Grant
    Filed: March 5, 1979
    Date of Patent: July 29, 1980
    Assignee: E. I. Du Pont de Nemours and Company
    Inventor: Hans H. Glaeser
  • Patent number: 4125586
    Abstract: A process for the removal of aluminum chloride from a liquid solution thereof with the liquid metal chlorides resulting from the chlorination of titaniferous materials by mixing water and sodium chloride with the liquid solution in amounts such that the amount of water is less than equimolar with respect to the total amount of aluminum chloride and the combined amount of water and sodium chloride is at least equimolar with respect to the total amount of aluminum chloride. This process significantly decreases the corrosion of apparatus associated with the presence of aluminum chloride and substantially eliminates losses of titanium tetrachloride and ferric chloride present in the liquid solution and reduces the formation of HCl.
