  • SOx additive systems based upon use of multiple particle species
    Patent number: 6281164
    Abstract: The useful life of SOx additives having a SO2→SO3 oxidation catalyst component and a SO3 absorption component can be extended by employing each of these components as separate and distinct physical particles, pellets, etc.
    Type: Grant
    Filed: February 2, 2000
    Date of Patent: August 28, 2001
    Assignee: Intercat-Savannah, Inc.
    Inventors: Edward J. Demmel, Albert A. Vierheilig, Regis B. Lippert
  • SO.sub.x Additive systems based upon use of multiple particle species
    Patent number: 6074984
    Abstract: The useful life of SO.sub.X additives having a SO.sub.2 .fwdarw.SO.sub.3 oxidation catalyst component and a SO.sub.3 absorption component can be extended by employing each of these components as separate and distinct physical particles, pellets, etc.
    Type: Grant
    Filed: September 3, 1997
    Date of Patent: June 13, 2000
    Assignee: Bulldog Technologies U.S.A., Inc.

  • SO.sub.x additive systems based upon use of multiple particle species
    Patent number: 6048821
    Abstract: The useful life of SO.sub.X additives having a SO.sub.2 .fwdarw.SO.sub.3 oxidation catalyst component and a SO.sub.3 absorption component can be extended by employing each of these components as separate and distinct physical particles, pellets, etc., with each component having large proportions of certain ingredients and having small proportions of certain other ingredients.
    Type: Grant
    Filed: November 18, 1996

  • Method and apparatus for controlling introduction of catalysts into FCC units
    Patent number: 5389236
    Abstract: The disclosed method and apparatus provides for providing addition of micro-spheroidal ("MS") Fluid Catalytic Cracking ("FCC") catalyst additives and/or bulk catalyst to an in situ circulating, active catalyst inventory of a fluid catalytic cracking unit at times and rates precisely controlled to sustain an effective additive concentration. In a preferred version of this invention, each of a series of such apparatus comprising one such device for each catalyst additive, is operated on a basic cycle time length during a portion of which the unit is engaged in active addition while in the remainder of the time it is passive.
