  • Heater and cookware for flameless catalytic combustion
    Patent number: 11877687
    Abstract: A heater or article of cookware is formed of a metal sheet with a first and second surface. A metal oxide layer is formed on the first surface of the sheet and a combustion catalyst is impregnated into the metal oxide layer. Fuel and air is then supplied to the first side of the metal sheet resulting in flameless catalytic combustion which heats the metal sheet.
    Type: Grant
    Filed: September 19, 2019
    Date of Patent: January 23, 2024
    Assignee: The United States of America as represented by the Secretary of the Army

  • Heater
    Patent number: 10584869
    Abstract: A heater having a planar metal sheet with a first and second surface. A metal oxide layer is formed on the first surface of the sheet and a combustion catalyst is impregnated into the metal oxide layer. A source of fuel and air is then supplied to the first side of the metal sheet resulting in catalytic combustion which heats the metal sheet. The metal sheet can serve as a cooking stove.

  • Catalyst and process of hydrocarbon feedstock reformation to hydrogen and carbon monoxide
    Patent number: 8709378
    Abstract: A catalytic composition is particularly well suited for hydrocarbon conversion to synthesis gas at a temperature of between 800 and 1000° Celsius. The catalytic composition includes a noble metal cluster having an X-Y-Z axial mean linear dimension of between 2 and 15 Angstroms and a super cage structure surrounding the noble metal cluster. The super cage structure stabilizes the noble metal cluster against aggregation at temperatures of 1000° Celsius. A process for reforming hydrocarbon feedstock to hydrogen and carbon monoxide is also provided that conversion to greater than 80% of theoretical yield.
