Method and device for using residual O2 for further CH4 production

摘要

The invention relates to a new method and a corresponding device for the conversion of carbon dioxide and hydrogen to methane. Possible areas of application are increasing the proportion of methane in biogas plants to over 85% methane. The device comprises reactors which have anaerobic methane-forming bacteria from sludge granules and, above them, catalysts / microbial settlement areas made from organic plastics, minerals or metallic substances with a specifically very large surface area, characterized in that the reactor rooms are multiple in a micro-column to form a multiple reactor are piled up.
