초록 ▼

An anaerobic digester is fed a feedstock, for example sludge from a municipal wastewater treatment plant, and produces a digestate. The digestate is dewatered into a cake. The cake may be dried further, for example in a thermal drier. The cake is treated in a pyrolysis system to produce a synthesis gas and biochar. The gas is sent to the same or another digester to increase its methane production. The char may be used as a soil enhancer.

대표청구항 ▼

1. A process for converting a feedstock to biogas comprising steps of, a) producing a synthesis gas from pyrolysis of the feedstock;b) separating organic compounds from the synthesis gas and returning the separated organic compounds to step a) as additional feedstock; and,c) adding the synthesis gas to an anaerobic digester. 2. The process of claim 1 wherein the feedstock comprises one or more of a raw biomass, wood, municipal yard waste, municipal solids waste, primary sludge from a wastewater treatment plant, waste activated sludge from a wastewater treatment plant or an agricultural waste or residue. 3. The process of claim 1 wherein the feedstock comprises digestate. 4. The process of claim 3 wherein the digestate is produced by the anaerobic digester. 5. The process of claim 1 wherein the anaerobic digester is coupled with or part of a municipal wastewater treatment plant, or an agricultural or industrial digester. 6. The process of claim 1 wherein the synthesis gas is cooled before it is fed to the digester. 7. An apparatus for transferring syngas to digestate comprising, a) a pipe between a source of digestate and a digester;b) a pump to create a flow of digestate in the pipe;c) an ejector, microbubble pump or gas transfer membrane in communication with the pipe and having an inlet connected to a source of the syngas; and,a heat exchanger between the inlet and the source of the syngas. 8. The apparatus of claim 7 wherein the source of digestate is the digester. 9. The apparatus of claim 7 wherein the pipe is connected to multiple outlets in the digester. 10. The apparatus of claim 7 wherein the inlet is further connected to the headspace of the digester. 11. The apparatus of claim 7 wherein the heat exchanger provides heat to a digestate cake drier. 12. A process and apparatus for treating wastewater comprising, a) treating the wastewater to generate a sludge;b) feeding the sludge to an anaerobic digester to produce biogas and digestate;c) dewatering the digestate to produce a cake;d) thermally drying the cake to produce a dried cake;e) pyrolysing the dried cake to produce char, organic compounds and syngas;f) feeding the syngas to the anaerobic digester; and,g) pyrolysing at least some of the organic compounds to produce additional syngas and feeding the additional syngas to the anaerobic digester. 13. The process of claim 12 further comprising extracting heat from the syngas and using the extracted heat in step d). 14. The process of claim 12 comprising using the char as a soil enhancer.
