  • Hydrodesulfurization of petroleum residuum utilizing a carbon-supported catalyst
    Patent number: 4032435
    Abstract: A hydrodesulfurization catalyst consisting essentially of a carbon support carrying thereon at least 10 and up to 20 weight percent of a first metal selected from tungsten and molybdenum and from about 2 to 10 weight percent of a second metal selected from cobalt and nickel, said metals being in the form of their sulfides and said catalyst having an average pore radius of at least 25 angstrom units and a compacted bulk density of about 0.3-0.8 gram per cc. provide advantages in the hydrodesulfurization of petroleum residuum.
    Type: Grant
    Filed: September 22, 1976
    Date of Patent: June 28, 1977
    Assignee: American Cyanamid Company
    Inventors: Joseph Lawrence Schmitt, Jr., George Augustus Castellion
  • Catalysts based on carbon supports and use in catalytic deoxidation process
    Patent number: 4031137
    Abstract: Carbon particulates comprising carbon black spheres and a carbon binder having large pores as well as desirable pore size distribution are disclosed which serve as catalyst supports. The support carrying an effective amount of an activator is an active catalyst composition for a variety of reactions including reduction reactions.
