Patents by Inventor Steve J. Pontonio

Steve J. Pontonio has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8609580
    Abstract: The present invention provides catalytic adsorbents formed from doping activated carbon with a dispersed halide salt. The catalytic adsorbents provided herein are stable and harmless at room temperature, yet allow for chemical adsorption at elevated temperatures typical of those for flue gas streams. The present invention also provides methods of manufacturing the doped activated carbon adsorbents.
    Type: Grant
    Filed: August 26, 2011
    Date of Patent: December 17, 2013
    Assignee: Praxair Technology, Inc.
    Inventors: Chien-Chung Chao, Steve J. Pontonio
  • Patent number: 8329614
    Abstract: Solid adsorbents, following their use for mercury removal from flue gas, that do not interfere with the ability of air-entraining additives (such as surfactants) to form stable bubbles when added to fly ash containing the adsorbents. The interference is overcome by heating the materials used in the manufacture of the adsorbent so that magnesium hydroxide and/or one or more alkali compounds containing one or more silicate, aluminate, and/or phosphate moiety, added or already present in the materials, binds multivalent cations present in the materials that could otherwise interfere with the surfactant activity.
    Type: Grant
