Abstract: The present invention is generally directed to a reactor for the production of low-carbon syngas from captured carbon dioxide and renewable hydrogen. The hydrogen is generated from water using an electrolyzer powered by renewable electricity or from any other method of low-carbon hydrogen production. The improved catalytic reactor is energy efficient and robust when operating at temperatures up to 1800° F. Carbon dioxide conversion efficiencies are greater than 75% with carbon monoxide selectivity of greater than 98%. The catalytic reactor is constructed of materials that are physically and chemically robust up to 1800° F. As a result, these materials are not reactive with the mixture of hydrogen and carbon dioxide or the carbon monoxide and steam products.

Abstract: Production of fuels from low carbon electricity and from carbon dioxide by the use of a solid oxide electrolysis cell (SOEC) and Fischer-Tropsch is shown. Fischer-Tropsch is an exothermic reaction that can be used to produce steam. Steam produced from the Liquid Fuel Production (LFP) reactor system, where the Fischer-Tropsch reaction occurs, is used as feed to the SOEC. The higher temperature steam improves the efficiency of the overall electrolysis system. The integration of the LFP steam improves the efficiency of the electrolysis because the heat of vaporization for the liquid water does not have to be supplied by the electrolyzer.

Abstract: The present invention is generally directed to processes and systems for the purification and conversion of CO2 into low-carbon or zero-carbon high quality fuels and chemicals using renewable energy. In one aspect, the present invention provides a process for producing a stream comprising at least 90 mol % CO2. In certain cases, the CO2 stream is processed to make low carbon fuels and chemicals. In this process at least a portion of the CO2 is reacted with a stream comprising H2 in a Reverse Water Gas Shift (RWGS) reactor to produce a product stream that comprises CO.

Abstract: The present invention is generally directed to the efficient production of low-carbon methanol, ethanol or mixtures of methanol and ethanol from captured CO2 and renewable H2 at a generation site. The H2 is generated from water using an electrolyzer powered by renewable electricity, or from any other means of low-carbon H2 production. An improved catalyst and process is described that efficiently converts H2 and CO2 mixture to syngas in a one-step process, and alcohols, such as methanol and ethanol, are produced from the syngas in a second step. The liquid methanol and ethanol, which are excellent H2 carriers, are transported to a production site, where another improved catalyst and process efficiently converts them to syngas. The syngas can then be used at the production site for the synthesis of low carbon fuels and chemicals, or to produce purified low carbon H2. The low carbon H2 can be used at the production site for the synthesis of low-carbon chemical products or compressed for transportation use.

The syngas can be used for the synthesis of low-carbon fuels and chemicals, or for the production of purified H2.
