초록 ▼

Methods are disclosed for extracting hydrogen from a biomass compound comprising carbon, oxygen, and hydrogen. The biomass may include cellulose, lignin, and/or hemicellulose. Water is combined with the compound to produce a wet form of the compound. The wet form of the compound is transferred into a reaction processing chamber. The wet form of the compound is heated within the reaction chamber such that elements of the compound dissociate and react, with one reaction product comprising hydrogen gas. The hydrogen gas is processed to generate electrical power.

1. A method for extracting hydrogen from a compound comprising carbon, oxygen, and hydrogen, the method comprising: determining an amount of water to combine with the compound, wherein: the determined amount of water to combine with the compound equals Mw−W*MT;W equals a weight percent water of the compound;Mw equals a mass water to add per mass of the compound as dry input mass; andMT equals a total mass of the compound;combining the determined amount of water with the compound to produce a wet form of the compound;transferring the wet form of the compound into a reaction processing chamber;heating the wet form of the compound within the reaction chamber such that elements comprised by the wet form of the compound dissociate and react with each other through at least a hydrous pyrolysis reaction, wherein one reaction product comprises hydrogen gas; andextracting the hydrogen gas, wherein extracting the hydrogen gas comprises passing reaction-product gases through a reduced pressure chamber to remove traces of unreacted carbon. 2. The method recited in claim 1 wherein the compound consists of carbon, oxygen, and hydrogen. 3. The method recited in claim 1 wherein the compound comprises cellulose. 4. The method recited in claim 1 wherein the compound comprises lignin. 5. The method recited in claim 1 wherein the compound comprises hemicellulose. 6. The method recited in claim 1 wherein the compound comprises a combination of cellulose, lignin, and/or hemicellulose. 7. The method recited in claim 1 further comprising providing a flow of an inert gas to the reaction chamber. 8. The method recited in claim 7 wherein the inert gas comprises at least argon or nitrogen. 9. The method recited in claim 1 wherein the extracted hydrogen gas is processed to generate at least electrical power or heat. 10. The method recited in claim 1 wherein the extracted hydrogen gas is processed to produce liquid fuels. 11. The method recited in claim 1 wherein the extracted hydrogen gas is processed by burning the hydrogen gas. 12. The method recited in claim 1 wherein the extracted hydrogen gas is processed by feeding the hydrogen gas into a fuel cell. 13. The method recited in claim 1 wherein the water comprises liquid water. 14. The method recited in claim 1 wherein extracting the hydrogen gas comprises passing reaction-product gases through a water-cooled chamber to remove unreacted water. 15. The method recited in claim 1 wherein heating the wet form of the compound comprises heating the wet form of the compound to a temperature between 700° C. and 1100° C. 16. The method recited in claim 1 wherein transferring the wet form of the compound into a reaction processing chamber occurs continuously. 17. The method recited in claim 16 wherein the continuous transfer of the wet form of the compound into the reactor that utilizes a geometry that reduces the presence of air. 18. The method recited in claim 1, wherein heating the wet form of the compound within the reaction chamber such that the elements comprised by the wet form of the compound dissociate and react with each other through at least the hydrous pyrolysis reaction occurs without an addition of steam. 19. The method recited in claim 1, wherein determining the amount of water to combine with the compound comprises: determining a weight percent water of the compound; anddetermining a remaining mass of water to combine with the compound to form the wet form of the compound, wherein the remaining mass of water depends on the determined weight percent water of the compound.
