Abstract
The present invention relates to a process for producing methane and to the device for producing methane, making it possible to increase the methane content of the outgoing gas and preferably simultaneously to increase the methane content of the outgoing gas and the productivity of the reactor.
Claims6
An ex-situ process for producing methane, comprising:
- a step (a), in a first bioreactor comprising methanogenic microorganisms in a liquid medium, of production of a gas mixture comprising methane, comprising bringing said microorganisms into contact with incoming gases;
- a step (b), in a second bioreactor, of methane enrichment of the gas mixture obtained in step (a), comprising transferring, from the first bioreactor to the second bioreactor, the gas mixture obtained in step (a) and at least a portion of the liquid medium contained in the first bioreactor, so as to increase the methane content in the gas mixture.
