The present invention describes a processes, systems, and catalysts for the conversion of carbon dioxide and water and electricity into low carbon or zero carbon high quality fuels and chemicals. In one aspect, the present invention provides an integrated process for the conversion of a feed stream comprising carbon dioxide to a product stream comprising hydrocarbons between 5 and 24 carbon atoms in length.

Process for conversion of carbon dioxide and power into fuels and chemicals

The invention relates to a process, catalysts, materials for conversion of renewable electricity, air, and water to low or zero carbon fuels and chemicals by the direct capture of carbon dioxide from the atmosphere and the conversion of the carbon dioxide to fuels and chemicals using hydrogen produced by the electrolysis of water.

Process for capture of carbon dioxide from air and the direct conversion of carbon dioxide into fuels and chemicals

The present invention is generally directed to processes and systems for the purification and conversion of COinto 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 % CO. In certain cases, the COstream is processed to make low carbon fuels and chemicals. In this process at least a portion of the COis reacted with a stream comprising Hin a Reverse Water Gas Shift (RWGS) reactor to produce a product stream that comprises CO.

Process for purification and conversion of carbon dioxide using renewable energy

The present invention describes a processes, systems, and catalysts for the utilization of carbon dioxide into high quality synthesis gas that can then be used to produce fuels (e.g., diesel fuel) and chemicals. In one aspect, the present invention provides a process for the conversion of a feed gas comprising carbon dioxide and hydrogen to a product gas comprising carbon monoxide and water.

Reverse water gas shift catalytic reactor systems

An integrated facility to produce either renewable diesel fuel or sustainable aviation fuel, or both renewable diesel and sustainable aviation fuel from carbon dioxide including carbon dioxide that is a byproduct of reacting Hydroprocessed Esters and Fatty Acids (HEFA) and hydrogen that produces renewable fuels. HEFA is hydroprocessed to produce a liquid fuel product and may produce water, CO and water, or CO2. Integrated with an eFuels process that produces the hydrogen that is needed in various steps of the integrated process. Renewable or low carbon electricity is used to convert water to hydrogen and oxygen in an electrolyzer. Carbon dioxide is reacted with at least a portion of the hydrogen to produce a stream comprising carbon monoxide with a carbon dioxide conversion per pass of between 50% to 100%, preferably between 60% and 100%, and more preferably between 70% and 100%.

Herein disclosed is a method of reducing greenhouse gas (GHG) emission comprising introducing one or more feed streams into a reformer to generate synthesis gas; and converting synthesis gas to dimethyl ether (DME). In some cases, the reformer is a fluidized bed dry reforming reactor. In some cases, the reformer comprises a hydrogen membrane. In some cases, the hydrogen membrane removes hydrogen contained in the synthesis gas and shifts reforming reactions toward completion.
