Abstract
Provided herein are systems and methods for controlling production of low-carbon liquid fuels and chemicals. In an aspect, provided herein is a method controlling a process that produces e-fuels. In another aspect, provided herein is a system for producing an e-fuel.
Claims14
A method for controlling a process that produces e-fuels, the method comprising:
- a. providing a first amount of electrical power to an electrolysis module to produce H2, mixing the H2 with CO2 to provide a gas mixture having a first ratio of H2 to CO2, performing a reverse water gas shift reaction on the gas mixture to produce synthesis gas, and reacting the synthesis gas to produce a liquid hydrocarbon;
- and
- b. in response to a stimulus, providing a second amount of electrical power to the electrolysis module to produce H2, mixing the H2 with CO2 to provide a gas mixture having a second ratio of H2 to CO2, performing a reverse water gas shift reaction on the gas mixture to produce synthesis gas, and reacting the synthesis gas to produce a liquid hydrocarbon,
- wherein the second amount of electrical power is an amount between 0 and the amount of electrical power of the first amount, and wherein the second ratio of H2 to CO2 is substantially similar to the first ratio of H2 to CO2.

A method for controlling a process that produces e-fuels, the method comprising:
- a. providing a first amount of electrical power to an electrolysis module to produce H2, wherein the electrolysis module is a module using alkaline electrolysis, membrane electrolysis, polymer electrolyte membrane electrolysis, solid oxide electrolysis or high temperature electrolysis, mixing the H2 with CO2 to provide a gas mixture having a first ratio of H2 to CO2, wherein the first ratio is between 2.0 and 4.0, performing a reverse water gas shift reaction on the gas mixture to produce synthesis gas, wherein the reverse water gas shift reaction is performed in a reverse water gas shift reactor comprising a catalyst, wherein the catalyst comprises a solid solution, transition metal catalyst, and reacting the synthesis gas with a liquid fuel production catalyst in a liquid fuel catalyst production reactor to produce a liquid hydrocarbon, wherein the liquid fuel production catalyst comprises cobalt or iron;
- and
- b. in response to a stimulus, wherein the stimulus is a signal associated with the availability of electrical power or the availability of CO2, providing a second amount of electrical power to the electrolysis module to produce H2, mixing the H2 with CO2 to provide a gas mixture having a second ratio of H2 to CO2, wherein the second ratio is between 2.0 and 4.0, performing a reverse water gas shift reaction on the gas mixture to produce synthesis gas, wherein the reverse water gas shift reaction is performed in a reverse water gas shift reactor comprising a catalyst, wherein the catalyst comprises a solid solution, transition metal catalyst, and reacting the synthesis gas with a liquid fuel production catalyst in a liquid fuel production reactor to produce a liquid hydrocarbon, wherein the liquid fuel production catalyst comprises cobalt or iron,
- wherein the second amount of electrical power is an amount between 0 and the amount of electrical power of the first amount.
