Abstract

In general, in one aspect, the invention relates to a method to convert carbon dioxide (CO 2 ) to an alcohol. The method involves contacting a stream of flue gas comprising the CO 2 from a combustion process with water mist to create a mixture of liquid carbonic acid (H 2 CO 3 ) and wastewater. The method further involves extracting the liquid H 2 CO 3 from the mixture and pressurizing the liquid H 2 CO 3 to generate pressurized liquid H 2 CO 3 . The method further involves combining the pressurized liquid H 2 CO 3 with a first liquid reagent in a first hydrolysis chamber creating the alcohol from combining the pressurized liquid H 2 CO 3 with the first liquid reagent.

Claims (38)

1. A method to convert carbon dioxide (CO 2 ) to a primary alcohol, the method comprising:

spraying a pressurized water mist into a directional flow of a stream of flue gas comprising the CO 2 from a combustion process to create heat and a mixture of liquid carbonic acid (H 2 CO 3 ) and wastewater;

extracting, using the heat, the liquid H 2 CO 3 from the mixture;

pressurizing the liquid H 2 CO 3 extracted from the mixture to generate pressurized liquid H 2 CO 3 ;

combining the pressurized liquid H 2 CO 3 with a first liquid reagent comprising lithium aluminum hydride (LiAlH 4 ) in a first hydrolysis chamber; and

creating the primary alcohol from combining the pressurized liquid H 2 CO 3 with the first liquid reagent comprising LiAlH 4 .

2. The method of claim 1 , further comprising:

extracting the primary alcohol from the hydrolysis chamber; and

using the primary alcohol as a fuel to generate power at the facility.

3. The method of claim 1 , wherein extracting the liquid H 2 CO 3 from the mixture comprises:

receiving the mixture in a trickling filter comprising a media onto which the mixture flows under aerobic conditions resulting in a layer of microbial film to form on the media; and

removing, using the layer of microbial film, microbial impurities from the mixture.

4. The method of claim 3 , wherein extracting the liquid H 2 CO 3 from the mixture further comprises:

receiving the mixture in a multi-bag filter system comprising a plurality of bags each comprising a pleated cartridge housed in a vessel and configured to remove oils and particles from the mixture.

5. The method of claim 4 , wherein extracting the liquid H 2 CO 3 from the mixture further comprises:

receiving the mixture in a heat exchanger;

heating, using the heat, the mixture in the heat exchanger to between a first and second temperature, wherein the first temperature is a boiling point of the H 2 CO 3 and wherein the second temperature is a boiling point of the wastewater;

converting liquid H 2 CO 3 to vapor H 2 CO 3 ;

receiving, in a steam separator, the mixture from the heat exchanger;

removing, using the steam separator, the vapor H 2 CO 3 from the mixture;

receiving, in a distiller, the vapor H 2 CO 3 from the steam separator; and

removing, using the distiller, the wastewater from the vapor H 2 CO 3 .

6. The method of claim 5 , wherein extracting the vapor H 2 CO 3 from the mixture further comprises:

receiving, using a condenser, the vapor H 2 CO 3 from the distiller;

cooling the vapor H 2 CO 3 to a third temperature below the first temperature; and

converting the vapor H 2 CO 3 to liquid H 2 CO 3 .

7. The method of claim 1 , wherein the mixture further comprises liquid sulfuric acid (H 2 SO 4 ) and liquid nitric acid (HNO 3 ).

8. The method of claim 7 , further comprising:

extracting, along with the liquid H 2 CO 3 , the liquid H 2 SO 4 and the liquid HNO 3 from the mixture;

heating, using a heat exchanger, the liquid H 2 CO 3 , the liquid H 2 SO 4 , and the liquid HNO 3 ;

converting the liquid H 2 CO 3 to vapor H 2 CO 3 , the liquid H 2 SO 4 to vapor H 2 SO 4 , and the liquid HNO 3 to vapor HNO 3 ;

separating the vapor H 2 CO 3 , the vapor H 2 SO 4 , and the vapor HNO 3 in a distiller;

separately condensing each of the vapor H 2 CO 3 , the vapor H 2 SO 4 , and the vapor HNO 3 to recreate the liquid H 2 CO 3 , the liquid H 2 SO 4 , and the liquid HNO 3 , respectively;

separately pressurizing each of the liquid H 2 CO 3 , the liquid H 2 SO 4 , and the liquid HNO 3 ;

combining pressurized liquid H 2 SO 4 with a second liquid reagent comprising an alkene in a second hydrolysis chamber;

creating a secondary alcohol from combining the pressurized liquid H 2 SO 4 with the second liquid reagent comprising the alkene;

combining pressurized liquid HNO 3 with a third liquid reagent comprising R—O—H (alcohol) in a third hydrolysis chamber; and

creating a tertiary alcohol from combining the pressurized liquid HNO 3 with the third liquid reagent comprising the R—O—H (alcohol).
