METHOD AND DEVICE FOR USING RESIDUAL CO2 FOR FURTHER CH4 PRODUCTION

摘要

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