Abstract

The present invention is directed to a method for utilizing CO₂ waste comprising recovering carbon dioxide from an industrial process that produces a waste stream comprising carbon dioxide in an amount greater than an amount of carbon dioxide present in starting materials for the industrial process. The method further includes producing hydrogen using a renewable energy resource and producing a hydrocarbon material utilizing the produced hydrogen and the recovered carbon dioxide.

Claims

1. A process for utilizing CO2 waste comprising:

recovering carbon dioxide from an industrial process that produces a waste stream comprising carbon dioxide in an amount greater than an amount of carbon dioxide present in starting materials for the industrial process;

producing hydrogen using a renewable energy resource; and

producing methane utilizing the produced hydrogen and the recovered carbon dioxide.

2. The process of claim 1, wherein the producing hydrogen is done by electrolysis of water using electricity generated from the renewable energy resource, and wherein the renewable energy resource comprises wind or solar energy.

3. The process of claim 1, wherein the producing hydrogen further comprises producing oxygen as a by-product and using the oxygen in a downstream process.

4. The process of claim 1, further comprising using electricity produced from the renewable energy resource to reduce an amount of carbon dioxide to a first amount of carbon monoxide and oxygen.

5. The process of claim 4, wherein the oxygen is utilized in the gasification of a carbon feedstock to produce a second amount of carbon monoxide, and wherein the second amount of carbon monoxide is utilized in a downstream process.

6. The process of claim 5, wherein at least one of the first amount or the second amount of the carbon monoxide and the produced hydrogen are converted to methanol via a catalytic process.

7. The process of claim 1, wherein the waste stream comprises an exhaust gas from a gas turbine engine.

8. The process of claim 4, further comprising reacting the produced hydrogen with the first amount of carbon monoxide in the presence of the recovered carbon dioxide to produce methanol.

9. The process of claim 1, further comprising converting the produced methane into methanol.

10. The process of claim 1, wherein the produced methane is thereafter converted into syngas.

11. The process of claim 1, further comprising converting the produced methane into carbon monoxide and a second hydrogen supply, wherein the carbon monoxide is directed for use in the production of methanol, and wherein the methanol is produced by reacting the carbon monoxide and at least one of the produced hydrogen from the renewable energy resource and the second hydrogen supply in the presence of the recovered carbon dioxide.

12. The process of claim 1, further comprising converting the produced methane into hydrogen and carbon monoxide and using the hydrogen and the carbon monoxide to produce methanol.
