| 摘要 |
The invention relates to a method for the production of biomethane from hydrocarbon feedstock (200), comprising at least the following steps: gasification (201) of the feedstock in order to produce a synthesis gas in a gasification reactor; purification (204), in a purification unit, of the synthesis gas produced during the biomass gasification step; methanisation (206) of the purified synthesis gas in a methanisation reactor; and adjustment to specifications (207) of the gas mixture obtained during the synthesis gas methanisation step, in order to obtain biomethane. During the specifications adjustment step, a flow comprising at least the excess carbon monoxide is recirculated (208) in the gasification reactor. The invention also relates to a device for carrying out the method of the invention. |
