Abstract

Biomass (e.g., plant biomass, animal biomass, and municipal waste biomass) is processed to produce useful products, such as fuels. For example, systems can use feedstock materials, such as cellulosic and/or lignocellulosic materials and/or starchy materials, to produce ethanol and/or butanol, e.g., by fermentation.

First claim

What is claimed is:

1. A method comprising:
saccharifying a cellulosic or lignocellulosic material comprising one or more functional groups, the one or more functional groups imparted to the cellulosic or lignocellulosic material from the cellulosic or lignocellulosic material having been ionized by a plurality of charged particles comprising ions and then contacted with a fluid selected to react with one or more species of radicals.

2. The method of claim 1 , wherein the one or more functional groups comprise one or more of: carboxylic acid groups, enol groups, aldehyde groups, nitro groups, nitrile groups, amino groups, alkyl amino groups, alkyl groups, chloroalkyl groups, and chlorofluoroalkyl groups.

3. The method of claim 1 , wherein the fluid comprises one or more of: acetylene, nitrogen, an ethylene, a chlorinated ethylene, a chlorofluoroethylene, a propylene, a diene, an antioxidant, or mixtures of one or more of these.

4. The method of claim 1 , wherein the cellulosic or lignocellulosic material that has been ionized by a plurality of charged particles and the fluid are contacted under a pressure of 1,000 psi or more.

5. The method of claim 1 , wherein the charged particles impart a dose of greater than 10 Mrad to the cellulosic or lignocellulosic material.

6. The method of claim 1 , wherein the charged particles are applied at a dose rate of about 1 Mrad/s to about 10 Mrad/s.

7. The method of claim 1 , wherein the charged particles comprise positively charged ions.

8. The method of claim 1 , wherein the charged particles comprise two or more different types of ions.

9. The method of claim 1 , wherein the charged particles comprise at least one of protons, hydride ions, carbon ions, oxygen ions, nitrogen ions, halogen ions, noble gas ions, silicon ions, phosphorus ions, and metal ions.

10. The method of claim 1 , wherein the charged particles comprise at least one of sodium ions, calcium ions, iron ions, platinum ions, palladium ions, iridium ions, rhodium ions, ruthenium ions, aluminum ions, rhenium ions, tungsten ions, and osmium ions.

11. The method of claim 1 , wherein the charged particles have an energy of 10 MeV/u or more.

12. A method comprising:
contacting a cellulosic or lignocellulosic material with a fluid selected to react with one or more species of radicals, the one or more species of radicals arising from the cellulosic or lignocellulosic material having been irradiated with a plurality of charged particles comprising ions at a dose of greater than 10 Mrad, the fluid effective to impart one or more functional groups to the cellulosic or lignocellulosic material.

13. The method of claim 12 , wherein the fluid comprises one or more of: acetylene, nitrogen, an ethylene, a chlorinated ethylene, a chlorofluoroethylene, a propylene, a diene, an antioxidant, or mixtures of one or more of these.

14. The method of claim 12 , wherein the one or more functional groups comprise one or more of: carboxylic acid groups, enol groups, aldehyde groups, nitro groups, nitrile groups, amino groups, alkyl amino groups, alkyl groups, chloroalkyl groups, and chlorofluoroalkyl groups.

15. The method of claim 12 , wherein the cellulosic or lignocellulosic material that has been ionized by a plurality of charged particles and the fluid are contacted under a pressure of 1,000 psi or more.

16. The method of claim 12 , wherein the charged particles impart a dose of greater than 10 Mrad to the cellulosic or lignocellulosic material.

17. The method of claim 12 , wherein the charged particles are applied at a dose rate of about 1 Mrad/s to about 10 Mrad/s.

18. The method of claim 12 , wherein the charged particles comprise positively charged ions.

19. The method of claim 12 , wherein the charged particles comprise two or more different types of ions.

20. The method of claim 12 , wherein the charged particles comprise at least one of protons, hydride ions, carbon ions, oxygen ions, nitrogen ions, halogen ions, noble gas ions, silicon ions, phosphorus ions, and metal ions.

21. The method of claim 12 , wherein the charged particles comprise at least one of sodium ions, calcium ions, iron ions, platinum ions, palladium ions, iridium ions, rhodium ions, ruthenium ions, aluminum ions, rhenium ions, tungsten ions, and osmium ions.

22. The method of claim 12 , wherein the charged particles have an energy of 10 MeV/u or more.

23. A method comprising:
contacting a cellulosic or lignocellulosic material with a fluid selected to react with one or more species of radicals, the one or more species of radicals arising from the cellulosic or lignocellulosic material having been irradiated with a plurality of charged particles at a dose of greater than 10 Mrad, the fluid effective to impart one or more functional groups to the cellulosic or lignocellulosic material, wherein the charged particles have an energy of 10 MeV/u or more.
