Abstract

Claims (40)

1. A method of producing an oxygenated fuel from biomass waste for use in a combustion system, the method comprising:

dissociating the biomass waste to produce one or more carbon donors comprising hydrocarbon and alcohol;

reacting the biomass waste produced carbon donors with an oxygen donor comprising steam to produce the oxygenated fuel comprising oxygenated carbon, wherein the reacting comprises:

applying energy recovered from an external energy source to the reaction of the one or more carbon donors and the oxygen donor, wherein the reacting comprises reacting the hydrocarbon and alcohol with the steam to produce carbon monoxide and hydrogen; and

combusting the oxygenated fuel in the combustion system.

2. The method of claim 1 , wherein the one or more carbon donors comprise carbon; and

wherein the reacting comprises partially oxidizing the carbon to produce carbon monoxide and carbon dioxide.

3. The method of claim 1 wherein combusting the oxygenated fuel in the combustion system comprises:

providing an oxidant and the oxygenated fuel in a combustion zone of the combustion system.

4. The method of claim 1 further comprising:

controlling timing or duration of fuel injection using adaptive control.

5. The method of claim 1 , further comprising:

controlling a fuel delivery pressure using adaptive control.

6. The method of claim 1 , wherein the combustion system comprises a stratified-charge combustion system.

7. A method of producing an oxygenated fuel from biomass waste for use in a combustion system, the method comprising:

applying waste heat recovered from an external heat source to the biomass waste;

dissociating the biomass waste under an anaerobic reaction to produce the oxygenated fuel comprising oxygenated carbon and hydrogen, wherein the dissociating the biomass waste under the anaerobic reaction comprises:

producing carbon in addition to the oxygenated carbon, and

reacting the carbon with an oxygen donor in the presence of waste heat to generate additional oxygenated carbon; and

combusting the oxygenated fuel in the combustion system.

8. The method of claim 7 , wherein dissociating the biomass waste under the anaerobic reaction comprises producing hydrocarbon and alcohol in addition to oxygenated carbon; and

reacting the hydrocarbon and alcohol with an oxygen donor in the presence of the waste heat to generate additional oxygenated carbon.

9. The method of claim 7 , wherein combusting the oxygenated fuel in the combustion system comprises:

providing multiple layers of an oxidant and the oxygenated fuel in a combustion zone of the combustion system.

10. The method of claim 9 further comprising:

controlling timing or a duration of fuel injection using adaptive control.

11. The method of claim 9 further comprising:

controlling fuel delivery pressure in the combustion system.

12. The method of claim 7 , wherein the combustion system comprises a stratified-charge combustion system.

13. A method of recycling carbon to produce an oxygenated fuel comprising oxygenated carbon and hydrogen, the method comprising:

harvesting carbon dioxide emitted from an industrial process;

dissociating biomass waste under an anaerobic process to produce carbon monoxide and hydrogen for the oxygenated fuel along with one or more carbon donors;

generating thermochemically shifted carbon monoxide and additional hydrogen for the oxygenated fuel by reacting the harvested carbon dioxide with the biomass waste produced one or more carbon donors; and

performing at least one of:

utilizing at least one constituent of the fuel in a fuel cell, and

combusting the oxygenated fuel in a combustion system.

14. The method of claim 13 , wherein the one or more carbon donors comprise at least one of hydrocarbon and alcohol.

15. The method of claim 13 , wherein dissociating the biomass waste under the anaerobic process comprises applying waste heat recovered from an external heat source.

16. The method of claim 13 , wherein generating the thermochemically shifted carbon monoxide comprises applying waste heat recovered from an external heat source.

17. The method of claim 13 , wherein the combustion system comprises a stratified-charge combustion system.
