Abstract
The hydrocarbon production method includes a first production step of producing carbon monoxide using carbon dioxide contained in source gas, and a second production step of producing hydrocarbon using hydrogen contained in source gas and carbon monoxide. The source gas contains at least one of carbon dioxide, carbon monoxide, and hydrogen not derived from fossil fuel.
Claims17
A hydrocarbon production method comprising:
- a first production step of producing carbon monoxide using carbon dioxide contained in a source gas;
- a second production step of producing hydrocarbon using hydrogen contained in the source gas and the carbon monoxide, wherein the source gas comprises at least one of carbon dioxide, carbon monoxide, and hydrogen that are not derived from fossil fuel;
- a hydrocarbon gas separation step of separating a hydrocarbon gas having 4 or less carbon atoms from the hydrocarbon produced in the second production step;
- a combustion step of combusting the hydrocarbon gas;
- and
- a temperature raising step of sending to a preheater the combustion exhaust gas produced in the combustion step and raising the temperature of the source gas of the first production step and the second production step by the preheater with the combustion exhaust gas produced in the combustion step,
- wherein the source gas used in the first production step and the second production step comprises carbon dioxide recovered from the combustion exhaust gas.
