NOVELTY - Accelerating (P1) the production of methane from a biomass (102) involves decomposing a biomass to produce an gaseous effluent including methane (104); decomposing a portion of the gaseous effluent in the presence of catalysts to form a decomposed stream (122) including hydrogen, carbon dioxide, and carbon monoxide; converting all of the carbon monoxide in the decomposed stream to carbon dioxide to produce a feed stream (118) including hydrogen and carbon dioxide; and mixing the feed stream (S1) with the biomass to facilitate decomposition of the biomass.    USE - For accelerating the production of methane from a biomass e.g. sanitary wastewater, for generating consumable energy (claimed). The biomass also includes municipal solid wastes.    ADVANTAGE - In this method all of the carbon monoxide in decomposed stream is converted into to carbon dioxide to produce feed stream including hydrogen and carbon dioxide. This prevents or reduces the amount of poisonous carbon monoxide in feed stream which is fed to bioreactor, secondly, it provides bacteria in bioreactor with the species consumed in methane production, i.e., hydrogen and carbon dioxide. The hydrogen and carbon dioxide provide an immediate electron and carbon source for the bacteria; the feed stream increases the contact area between the bacteria and the available food sources; since the external feed stream is at an elevated temperature, it enhances the digestion rate within the bioreactor. The systems and methods provide a sustainable alternative energy source and can be easily integrated into existing wastewater treatment plants. The power generated can be used to operate other conventional equipment within the existing wastewater treatment plant. It reduces the treatment costs to the facility while also saving energy. They can even be used as a stand alone technique in niche applications. The bioreactor system having a feed stream of hydrogen and carbon dioxide generated more methane (e.g. 8.16 lb mol/min of methane as compared to a traditional bioreactor that did not include a feed stream of hydrogen and carbon dioxide, which generated 7.65 lb mol/min of methane).    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following    (1) a method of accelerating the generation of a consumable energy from a biomass involving steps of process (P1) followed by feeding a portion of the gaseous effluent to a power plant (124); and generating a consumable energy with a portion of the gaseous effluent; and    (2) a system (100) for accelerating the generation of methane from a biomass comprising: a bioreactor (106, 110) for decomposing a biomass to produce a gaseous effluent including methane; a catalytic reforming reactor (120) for decomposing a portion of the gaseous effluent in the presence of catalysts to form a decomposed stream (122) including hydrogen, carbon dioxide, and carbon monoxide; a shift reactor (128) for converting substantially all of the carbon monoxide in the decomposed stream to carbon dioxide to produce a feed stream including hydrogen and carbon dioxide; and a conduit from the shift reactor to the bioreactor for directing the feed stream to the bioreactor to facilitate decomposition of the biomass.
