  • Supported catalyst systems
    Patent number: 6893995
    Abstract: Disclosed are methods of producing a supported organic catalyst system comprising the steps of: (a) providing an organic catalyst solution comprising an organic catalyst dissolved in a supercritical-like solvent; (b) contacting a support material with the organic catalyst solution; and (c) removing substantially all of the supercritical-like solvent from the organic catalyst and the support material.
    Type: Grant
    Filed: November 28, 2001
    Date of Patent: May 17, 2005
    Assignee: Honeywell International Inc.

  • Method of introducing refrigerants into refrigeration systems
    Patent number: 6516837
    Abstract: Provided are methods of introducing environmentally desirable refrigerants into refrigeration systems. The present methods involve recharging a refrigerant system that contains a chlorine-containing refrigerant and a lubricant comprising the steps of (a) removing the chlorine-containing refrigerant from the refrigeration system while retaining a substantial portion of the lubricant in said system; and (b) introducing to said system a composition comprising: (i) a refrigerant; (ii) a surfactant; and (iii) a solubilizing agent.
    Type: Grant
