  • Regeneration of HDS catalysts
    Patent number: 4698321
    Abstract: Regeneration of HDS catalysts by sulfiding under controlled conditions and leaching the sulfided catalyst with an acidic aqueous ferric ion containing solution to remove contaminating nickel and vanadium compounds and recovering catalyst of increased BET surface area and pore diameter.
    Type: Grant
    Filed: August 8, 1985
    Date of Patent: October 6, 1987
    Assignee: Georgia Tech Research Corporation
    Inventors: Allan S. Myerson, William R. Ernst
  • Removal of inorganic contaminants from catalysts
    Patent number: 4559313
    Abstract: Spent catalysts containing metal impurities are treated by a process comprising treating the spent catalyst with a solution containing oxidizing ferric ion and/or oxidizing bacteria, thereby freeing said spent catalyst of said metal impurities.
    Type: Grant
    Filed: July 25, 1983
    Date of Patent: December 17, 1985
    Assignee: Georgia Tech Research Institute
    Inventors: Allan S. Myerson, William R. Ernst
  • Catalytic hydrolysis of carbonyl sulfide
    Patent number: 4524050
    Abstract: Hydrolysis of COS in gas streams to H.sub.2 S and CO.sub.2 can be improved by using certain bicyclo tertiary amine catalysts. Bicyclo tertiary amine catalysts can enhance COS hydrolysis in an acid gas removal solvent in the liquid phase or on a solid support system in the gas phase.
