  • Patent number: 9234215
    Abstract: A method for operating a fermentation plant with at least one digester (1) that is supplied with a substrate (1a). The substrate (1a) is percolated using a percolate (2a) from a percolate container (2) and biogas that is generated via the percolation process in the digester (1) or/and in the percolate container (2) is drawn off. The drawn off biogas is treated in a biogas treatment device (3) and the CO2-containing exhaust gas that is generated during the treatment is introduced into the digester (1) using a purge line (4), for forcing out and drawing off the biogas that was generated in the digester (1). Alternatively CO2-containing biogas that was generated in an additional digester (1) in a different fermentation process can be introduced into the digester (1) using a purge line (4) for forcing out and drawing off the biogas that was generated in the digester (1).

  • Patent number: 9216916
    Abstract: In accordance with one embodiment, a process is described for a water treatment process in which water produced from a fuel production process is treated with recycled biochar. In accordance with one aspect, process water is passed through activated carbon generated by the biomass pyrolysis and gasification. In accordance with another aspect, the process water is treated to expel gaseous compounds within the process water. In this manner both inorganics, light organics and heavy organics can be removed from the process water. No fermentation is involved.

  • 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.
