Abstract

An energy product made from biomass, and a method of making an energy product from biomass. The energy product is made by processing biomass in a pressurizable reaction vessel with heat, pressure and agitation.

Claims (28)

1. A method for creating an energy product from the cellulosic fraction of biomass, which comprises the steps of:

adding biomass to a sealable reaction vessel;

rotating said reaction vessel while adding steam at 15 psig or less to said biomass; and

separating a cellulosic fraction of the treated biomass from other fractions of the treated biomass to thus form a combustible energy product.

2. The method for creating an energy product from the cellulosic fraction of biomass of claim 1 , which further includes the step of agitating the biomass in the reaction chamber by rotation of the reaction vessel and by action of auger vanes within said reaction vessel.

3. The method for creating an energy product from the cellulosic fraction of biomass of claim 1 , which includes the step of providing a reaction chamber with an access door at one end, with a door cover which may be sealed on said access door during the heating and pressure step, and unsealed from said access door for input and removal of biomass.

4. The method for creating an energy product from the cellulosic fraction of biomass of claim 1 , which further includes the step of cooling the treated biomass after removal from the reactor.

5. The method for creating an energy product from the cellulosic fraction of biomass of claim 1 , which further includes the step of providing a condensation chamber for said reaction vessel, in which gases from said reaction chamber may be routed and condensed to remove odors and off-gas before the biomass is discharged from the reaction vessel.

6. The method for creating an energy product from the cellulosic fraction of biomass of claim 1 , which further includes the step of rotating the reaction vessel and heating the biomass for approximately 45 minutes or less by injecting steam through one or more sparging lines associated with said reaction vessel.

7. The method for creating an energy product of claim 1 , which includes the step of adding said biomass to a generally cylindrical reaction vessel with internal auger flights for agitation and moving of said biomass.

8. The method for creating an energy product from the cellulosic fraction of biomass of claim 1 wherein the vessel is configured for agitation of said biomass and further includes the step of closing the reaction vessel.

9. The method for creating an energy product from the cellulosic fraction of biomass of claim 1 , wherein the steam is added to the biomass while the biomass is being agitated in the reaction vessel.

10. The method for creating an energy product from the cellulosic fraction of biomass of claim 1 further including the step of unsealing the reaction vessel and removing the treated biomass from the reaction vessel.

11. A method of separating cellulosic biomass from biomass waste streams, which comprises the steps of:

adding biomass to a sealable reaction vessel;

rotating said reaction vessel while adding steam at 15 psig or less to said biomass and

separating the cellulosic fraction of the treated biomass from other fractions of the treated biomass.

12. The method of separating cellulosic biomass from biomass waste streams of claim 11 , which further includes the step of agitating the biomass in the reaction chamber by rotation of the reaction vessel and by action of auger vanes within said reaction vessel.

13. The method of separating cellulosic biomass from biomass waste streams of claim 11 , which includes the step of providing a reaction chamber with an access door at one end, with a door cover which may be sealed on said access door during the heating and pressure step, and unsealed from said access door for input and removal of biomass.

14. The method of separating cellulosic biomass from biomass waste streams of claim 11 , which further includes the step of cooling the treated biomass after removal from the reactor.

15. The method of separating cellulosic biomass from biomass waste streams of claim 11 , which further includes the step of providing a condensation chamber for said reaction vessel, in which gases from said reaction chamber may be routed and condensed to remove odors and off-gas before the biomass is discharged from the reaction vessel.

16. The method of separating cellulosic biomass from biomass waste streams of claim 11 , which further includes the step of rotating the reaction vessel and heating the biomass for approximately 45 minutes or less by injecting steam through one or more sparging lines associated with said reaction vessel.

17. The method of separating cellulosic biomass from biomass waste streams of claim 11 , which includes the step of adding said biomass to a generally cylindrical reaction vessel with internal auger flights for agitation and moving of said biomass.

18. The method of separating cellulosic biomass from biomass waste streams of claim 11 , further comprising forming said cellulosic pulp into an energy product.

19. The method of separating cellulosic biomass from biomass waste streams of claim 18 wherein said energy product is formed by compressing said cellulosic biomass into a selected shape for combustion.

20. The method for creating an energy product from the cellulosic fraction of biomass of claim 11 wherein the vessel is configured for agitation of said biomass and further includes the step of closing the reaction vessel.

21. The method for creating an energy product from the cellulosic fraction of biomass of claim 11 , wherein the steam is added to the biomass while the biomass is being agitated in the reaction vessel.

22. The method for creating an energy product from the cellulosic fraction of biomass of claim 11 further including the step of unsealing the reaction vessel and removing the treated biomass from the reaction vessel.
