Patents by Inventor Veronica M. Irurzun

Veronica M. Irurzun 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).

  • Sulfided iron (II) compound and method of manufacture
    Patent number: 9458027
    Abstract: The invention involves the formation of a sulfided stable iron (II) compound from an iron (II) oxide and/or hydroxide and where the molar ratio of sulfur to iron (II) is greater than 1. Preferably these oxides and/or hydroxides are present as nanoparticles in the 5-10 nanometer range. It has been discovered that such particles can be formed at lower cost and with fewer impurities by using ferrous carbonate (FeCO3) from siderite as compared to known processes from various iron salts such as sulfates and chlorides.
    Type: Grant
    Filed: February 10, 2015
    Date of Patent: October 4, 2016
    Assignee: New Technology Ventures, Inc.
    Inventors: Floyd E. Farha, Veronica M. Irurzun

  • Highly active nano iron catalyst for the absorption of hydrogen sulfide
    Patent number: 9023237
    Abstract: The invention involves the formation of a stable iron (II) oxide and/or hydroxide. Preferably these oxides and/or hydroxides are present as nanoparticles in the 5-10 nanometer range. It has been discovered that such particles can be formed at lower cost and with fewer impurities by using ferrous carbonate (FeCO3) from siderite as compared to known processes from various iron salts such as sulfates and chlorides. The novel nanoparticles are particularly adapted to removing sulfur compounds such as H2S from liquid and/or gaseous streams, such as hydrocarbon streams.
