  • Countercurrent hydroprocessing with treatment of feedstream to remove particulates and foulant precursors
    Patent number: 6579443
    Abstract: A process for upgrading a liquid petroleum or chemical stream wherein said feedstream flows countercurrent to the flow of a treat gas, such as a hydrogen-containing gas, in at least one reaction zone. The feedstream is treated so that it is substantially free of particulate matter and foulant precursors.
    Type: Grant

    Date of Patent: June 17, 2003
    Assignee: ExxonMobil Research and Engineering Company
    Inventors: Larry L. Iaccino, Edward S. Ellis, Ramesh Gupta, Brenda A. Raich
  • Production of light olefins from oxygenate using framework gallium-containing medium pore molecular sieve
    Publication number: 20030018231
    Abstract: A method is provided for converting oxygenates, e.g., methanol, to olefins, e.g., ethylene and propylene, comprising contacting said oxygenates and an aromatics co-feed, e.g., xylenes, with a framework gallium-containing molecular sieve catalyst comprising pores having a size ranging from about 5.0 Angstroms to about 7.0 Angstroms, e.g., ZSM-5, under production conditions effective to produce olefins. A catalyst composition is also provided, comprising a ZSM-5 zeolite-bound ZSM-5 zeolite having a bound zeolite of framework Ga-containing zeolite having a Si/Ga molar ratio ranging from 5 to 500 and a binder of Ga-modified, e.g., Ga-exchanged and/or Ga-impregnated, zeolite having a Si/Ga molar ratio ranging from 5 to ∞.

  • Nanoporous carbon catalytic membranes and method for making the same
    Patent number: 6471745
    Abstract: Catalytic membranes comprising highly-dispersed, catalytically-active metals in nanoporous carbon membranes and a novel single-phase process to produce the membranes.
    Type: Grant
    Filed: October 26, 1999
    Date of Patent: October 29, 2002
    Assignee: University of Delaware
    Inventors: Henry C. Foley, Michael Strano, Madhav Acharya, Brenda A. Raich
  • Supported carbogenic molecular sieve membrane and method of producing the same
    Patent number: 5972079
    Abstract: Carbogenic molecular sieve devices comprising a porous support (e.g., a metal support) having a carbogenic molecular sieve membrane attached to one or more surfaces of the support so that small pores in the membrane are in communication with larger pores in the support and methods of making the devices.
