Abstract
As a hydrocarbon production system that synthesizes hydrocarbons using water and carbon dioxide as raw materials, a hydrocarbon production system capable of producing hydrocarbons by securing hydrogen and carbon monoxide required for hydrocarbon synthesis is provided. In a hydrocarbon production system that produces hydrocarbons from at least water and carbon dioxide, the hydrocarbon production system includes at least an electrolytic reaction unit, a reverse water-gas shift reaction unit, and a hydrocarbon synthesis reaction unit.
Claims17
A hydrocarbon production system comprising:
- an electrolytic reaction unit into which at least water and carbon dioxide are introduced, the electrolytic reaction unit comprising an electrolysis cell formed on a support, in which an electrode layer and a counter electrode layer are formed with an electrolyte layer interposed therebetween;
- an electrode layer-side gas supply path configured to supply water and carbon dioxide to the electrode layer and act as a discharge path configured to discharge hydrogen generated in the electrode layer;
- a reverse water-gas shift reaction unit configured to receive a gas containing hydrogen and carbon dioxide that is discharged from the discharge path;
- and
- a hydrocarbon synthesis reaction unit configured to synthesize hydrocarbons from an outlet gas of the reverse water-gas shift reaction unit,
- wherein a ratio of hydrogen and carbon monoxide introduced into the hydrocarbon synthesis reaction unit is adjusted by adjusting at least one of the following:
- a ratio of water and carbon dioxide introduced into the electrolytic reaction unit, reaction conditions of the electrolytic reaction unit, reaction conditions of the reverse water-gas shift reaction unit, or any combination thereof.
