摘要
(EP2739577) Systems and methods for integrating thermo chemical processing of biomass and anaerobic digestion are provided. Light oxygenated organic compounds are produced as byproducts of thermochemical biomass processing e.g. by torrefaction and/or pyrolysis, and are converted to methane by anaerobic digestion. Thermochemical processing units may or may not be co-located with the anaerobic digestion units, with co-location providing benefits for e.g. rural agricultural enterprises.

主权利要求
(EP2739577) 1. A system for the processing of at least one biomass source comprising;   an anaerobic digester (40, 400) suitable for the digestion of low solid content biomass comprising an aqueous organic material containing less than 20% by mass of solid materials;   at least one thermochemical reactor (10) suitable for the controlled degradation of high solid content biomass comprising solid with less than 50% water by mass;   a condenser system (20, 120, 220, 221) suitable to separate a fraction produced by the thermochemical reactor(10) ;   and a transfer system (30) to transport an aqueous fraction produced in the thermochemical reactor (10) into the anaerobic digester (40, 400), wherein the thermochemical reactor (10) is at least one thermochemical reactor (10) selected from a pyrolysis reactor (200) and a torrefaction reactor (100) and wherein if the thermochemical reactor (10) is a pyrolysis reactor (200), then the condenser system (20, 120, 220, 221) comprises a plurality of condensers. 2. The system of claim 1 wherein the thermochemical reactor (10) is a torrefaction reactor (100). 3. The system of claim 1 wherein the pyrolysis reactor (200) is configured to yield char in addition to the aqueous fraction. 4. The system of any one of claims 1 to 3 wherein the condenser system (20, 120, 220, 221) comprises a plurality of condensers each configured to concentrate a distinct fraction produced by the thermochemical reactor (10). 5. The system of claim 4 wherein the distinct fraction comprises a bio-oil that is not transferred into the anaerobic digester (40, 400). 6. The system of any of claims 1 to 5 wherein the condenser system (20, 120, 220, 221) is configured to separate a fraction of light oxygenated organic compounds which is transferred into the anaerobic digester (40, 400). 7. The system of claim-6 wherein the anaerobic digester (40, 400) is configured such that at least a fraction of methane produced by the anaerobic digester (40, 400) is utilized to produce a chemical needed to up-grade the bio-oil. 8. The system of any of claims 1 to 7 wherein the thermochemical reactor (10) is a two stage reactor comprising a first torrefaction stage (100) and a second pyrolysis stage (200). 9. The system of claim 8 wherein the torrefaction reactor (100) is configured to yield a solid torrefied biomass and a an aqueous fraction containing light oxygenated organic compounds of hydrocarbons having fewer than 5 carbon atoms and at least one oxygen atom for transfer into the anaerobic digester (40, 400). 10. A method for biomass conversion comprising: thermochemical treatment of a high solid biomass comprising solid with less than 50% water by mass to yield a biomass solid and an aqueous fraction comprising light oxygenated organic compounds of hydrocarbons having fewer than 5 carbon atoms and at least one oxygen atom; and anaerobic digestion of a low solid biomass comprising an aqueous organic material containing less than 20% by mass of soild materials and said aqueous fraction to yield methane, wherein the thermochemical treatment is a) in a temperature range of 150-350° C or b) in a temperature range of 300-500° C in a pyrolysis reactor or a torrefaction reactor, and a fraction comprising bio-oil is not transferred into the anaerobic digester (40, 400). 11. The method of claim 10 further comprising the step of separating fractions from said thermochemical treatment using one or more condensers. 12. The method of claim 10 or 11 wherein said high solids biomass comprises a product of said anaerobic digestion. 13. The method of any of claim 10 to 12 further comprising a step of converting at least some of the methane to hydrogen.
