Method for Converting Coal to Biogenic Methane

Description of Technology:

This technology is a method for converting coal to biogenic methane. The method comprises providing a solid coal matrix into soluble, coal-derived constituents, introducing indigenous microorganisms into the soluble, coal-derived constituents, and biologically converting the soluble, coal-derived constituents into methane.

Applications:

In-situ coal depolymerization and solubilization technologies can be used to transform a fraction of the solid coal matrix into soluble constituents that are more readily bio-available, thereby enhancing the production of secondary biogenic coal bed methane (CBM).

Features and Benefits:

The Method for Converting Coal to Biogenic Methane can benefit existing coal operations by greatly enhancing methane production. As an example, if only 0.1% of the available coal with the Powder River Basin were biogenically transformed into CBM, the estimated producible methane reserves with the basin would nearly double.
