Producing natural gas-quality methane, for use as fuel, comprises using a reactor in which carbon dioxide flows through porous material charged with nutrient solution containing microorganisms

摘要

Producing methane comprises using a reactor (R) in which carbon dioxide (or gas containing carbon dioxide) flows through porous material (12) charged with nutrient solution (13) containing microorganisms. An independent claim is included for a reactor, consisting of a container (1) having inlet(s) (6) and outlet(s) (7) and including the porous material (12) charged with nutrient solution (13) containing microorganisms.
