  • Patent number: 11794166
    Abstract: Perovskite oxides and catalysts containing the perovskite oxides are provided for the thermochemical conversion of carbon dioxide to carbon monoxide. The perovskite oxides can exhibit large carbon monoxide production rates and/or low carbon monoxide production onset temperatures as compared to existing materials. Reactors are provided containing the perovskite oxides and catalysts, as well as methods of use thereof for the thermochemical conversion of carbon dioxide to carbon monoxide.

  • Publication number: 20220081789
    Abstract: In one aspect, the disclosure relates to catalysts for electrochemical water splitting, in particular catalysts useful for oxygen evolution at an anode in electrochemical water splitting. The disclosed catalysts compositions comprise a catalyst core component, a shell component, and optionally a catalyst outer component; wherein the catalyst core component comprises a composition having the chemical formula MxPy; where M is a transition metal; wherein x is a number from about 1 to about 20; wherein y is a number from about 1 to about 20; wherein the shell component comprises a conducting polymer; and wherein the catalyst outer component is a transition metal that is not the same as the transition metal M. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present disclosure.

  • Patent number: 10144878
    Abstract: In some embodiments, method for producing liquid fuel from landfill gas, the method including providing landfill gas to a tri-reformer, performing a tri-reforming process on the landfill gas within the tri-reformer to convert the landfill gas into synthesis gas, wherein the tri-reforming process combines carbon dioxide reforming, steam reforming, water-gas shifting, and methane oxidation and wherein the synthesis gas has a H2:CO ratio of approximately 2:1, providing the synthesis gas to a Fischer-Tropsch synthesis (FTS) reformer, and converting the synthesis gas into liquid fuel within the FTS reformer.

  • Patent number: 10005963
    Abstract: In some embodiments, a system for producing liquid fuel from landfill gas includes a tri-reformer that receives landfill gas and produces synthesis gas having a H2:CO ratio of approximately 2:1, and a Fischer-Tropsch synthesis (FTS) reformer that receives the synthesis gas from the tri-reformer and produces liquid fuel.
