Abstract

According to the present invention, organic material is converted to biogas through anaerobic digestion and the biogas is purified to yield a combustible fluid feedstock comprising methane. A fuel production facility utilizes or arranges to utilize combustible fluid feedstock to generate renewable hydrogen that is used to hydrogenate crude oil derived hydrocarbons in a process to make transportation or heating fuel. The renewable hydrogen is combined with crude oil derived hydrocarbons that have been desulfurized under conditions to hydrogenate the liquid hydrocarbon with the renewable hydrogen. The present invention enables a party to receive a renewable fuel credit for the transportation or heating fuel.

Claims (26)

1. A method of transforming waste organic material to produce a liquid transportation or heating fuel comprising:

(a) subjecting waste organic material to anaerobic digestion by microorganisms in a biogas production facility that incorporates apparatus to collect the microbially generated biogas;

(b) collecting an amount of crude biogas from the biogas production facility;

(c) removing impurities from the crude biogas to yield a combustible fluid feedstock;

(d) introducing a first amount of combustible fluid feedstock from step (b) or (c) to apparatus for delivering a combustible fluid feedstock to a fuel production facility;

(e) withdrawing for use at a fuel production facility a second amount of combustible fluid feedstock;

(f) processing at the fuel production facility the second amount of combustible fluid feedstock to produce renewable hydrogen;

(g) producing a third amount of liquid transportation or heating fuel by a process that comprises combining renewable hydrogen derived from the second amount of combustible fluid feedstock with a desulfurized, crude oil derived liquid hydrocarbon in a reactor under conditions to hydrogenate the liquid hydrocarbon with the renewable hydrogen; and

(h) generating or causing generation of a renewable fuel credit.

2. The method of claim 1 , wherein the biogas production facility is a landfill, a sewage treatment facility or a manure digestion facility.

3. The method of claim 1 , wherein the reactor is a hydrogenation reactor.

4. The method of claim 1 , wherein the reactor is a hydrocracker.

5. The method of claim 1 , wherein the liquid transportation or heating fuel is selected from the group consisting of gasoline, diesel, heating oil and jet fuel.

6. The method of claim 1 , wherein a liquid transportation fuel is produced in step (g).

7. The method of claim 1 , wherein a renewable fuel credit is associated with said first or second amount of combustible fluid feedstock, the renewable hydrogen, the liquid transportation or heating fuel, or a combination thereof.

8. The method of claim 7 , wherein a renewable fuel credit is associated with said liquid transportation or heating fuel.

9. The method of claim 1 , wherein the liquid transportation or heating fuel is renewable or partially renewable.

10. A method of producing a transportation or heating fuel comprising:

(a) causing a first amount of combustible fluid feedstock to be introduced to apparatus for delivering a combustible fluid feedstock to a fuel production facility, said first amount of combustible fluid feedstock being derived from a crude biogas that was generated by anaerobic digestion of waste organic material and from which impurities were removed following collection from a biogas production facility;

(b) withdrawing for use at a fuel production facility, a second amount of combustible fluid feedstock;

(c) processing at the fuel production facility the second amount of combustible fluid feedstock to produce renewable hydrogen;

(d) producing a third amount of liquid transportation or heating fuel by a process that comprises combining renewable hydrogen derived from the second amount of combustible fluid feedstock with a desulfurized, crude oil derived liquid hydrocarbon in a reactor under conditions to hydrogenate the liquid hydrocarbon with the renewable hydrogen; and

(e) generating or causing generation of a renewable fuel credit.

11. The method of claim 10 , wherein the biogas production facility is a landfill, a waste treatment facility or a manure digestion facility.

12. The method of claim 10 , wherein the reactor is a hydrogenation reactor.

13. The method of claim 10 , wherein the reactor is a hydrocracker.
