ABSTRACT:
A method for carrying out a biochemical reaction with a culture of microorganisms is performed in a cavity formed in a subterranean formation to produce combustible hydrocarbon gases. The method is especially suitable for the conversion of alkali-oxidized or hydrolyzed coal, such as lignite, to methane. The method may be performed in the cavity as a continuously stirred tank reaction, or plug flow or as a staged reaction. The method may also be done as an anaerobic fixed film process using particles as an anaerobic filter, as a sludge blanket, or as an expanded bed process.
