Abstract:
Methanogenic archaea are able to produce methane by metabolization of H2 and CO2 or CO, and present therefore a second technological option, besides catalytic methanation, for the synthesis of biomethane or substitute natural gas (SNG). One major challenge to the implementation of this process is supplying and dissolving the feed gases to the aqueous environment of the microorganisms. Tackling this question, the project ORBIT aims at developing a new trickle-bed reactor for biological methanation and demonstrating this technology at an existing Power-to-Gas site. This contribution will present some results regarding the layout and design of the pre-pilot scale trickle-bed reactor. Furthermore, some experimental results from an existing bench-scale reactor will be shown.
