Tóm tắt

The present invention provides a method for generating methane from a carbonaceous fuel source with simultaneous sequestration of carbon dioxide, the method comprising anaerobically incubating a particulate alkaline earth metal salt in contact with a particulate and/or dissolved carbonaceous feedstock in a neutral or alkaline aqueous culture medium containing a culture of methanogenic bacteria consortia and collecting methane generated therefrom. At least a portion of carbon dioxide produced during the incubation reacts with the alkaline earth metal salt to form an alkaline earth metal carbonate, thereby sequestering the carbon dioxide.
