US 2026/0201426 A1 · EX-SITU BIOMETHANATION METHOD

Abstract

The present invention relates to an ex-situ biomethanation method as well as to the device for implementing the same. The invention relates to an ex-situ methane production method comprising the steps of placing in contact at least one methanogenic microorganism, a culture substrate and optionally a first culture medium in a gas/liquid bioreactor optionally comprising a second culture medium and producing methane by the reaction of incoming gases with the at least one methanogenic microorganism, characterized in that the culture substrate is optionally immobilized in the gas/liquid bioreactor; and the at least one methanogenic microorganism is fixed to the culture substrate; as well as to the device for carrying out the method.

Dependent claims

A method for the ex-situ methane production comprising the following steps:

a) placing in contact at least one methanogenic microorganism, a culture substrate and optionally a first culture medium and;
b) introducing the mixture obtained in step a) into a gas/liquid bioreactor optionally comprising a second culture medium;
c) contacting incoming gases in the gas/liquid bioreactor obtained in step b);
d) reaction of incoming gases with the at least one methanogenic microorganism;
e) recovery of outgoing gases obtained in step d);
characterized in that
the culture substrate is optionally immobilized in the gas/liquid bioreactor;
and
at least one methanogenic microorganism is fixed to the culture substrate.
