  • Methods for obtaining clean energy from coal
    Patent number: 9139780
    Abstract: The present invention provides methods for stimulating or enhancing the conversion of coal to methane. The methods of the current invention subject coal to an oxidation step, for example ozonolysis, thereby converting at least a portion of the coal to partially-oxidized and water-soluble forms of organic matter. Subsequent contact of the oxidized coal components with a suitable inoculum containing a methanogenic microbial community produces methane.
