Abstract
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.
Claims19
An integrated process for the conversion of a feed stream comprising carbon dioxide to a product stream comprising hydrocarbons, the process comprising:
- a. an electrolysis step where an electrolyzer feed stream comprising water is converted to an electrolyzer product stream comprising hydrogen and oxygen where at least a portion of the electricity used in the electrolysis step is from renewable or low carbon sources;
- b. a reverse water gas shift step where at least a portion of the hydrogen from the electrolyzer product stream is reacted with a stream comprising carbon dioxide to produce a reverse water gas shift product stream comprising carbon monoxide;
- c. a hydrocarbon synthesis step where at least a portion of the hydrogen from the electrolyzer product stream is reacted with a stream comprising at least a portion of the reverse water gas shift product stream to produce a hydrocarbon synthesis product stream comprising hydrocarbons;
- d. an auto-thermal reforming step where at least a portion of the oxygen produced by electrolysis is reacted with a stream or streams comprising a) unreacted reactants from the hydrocarbon synthesis step and b) products from the hydrocarbon synthesis step that are not hydrocarbons between 5 and 24 carbon atoms in length.
