METHODS AND SYSTEMS FOR GENERATING HYDROGEN FROM A BIOMASS

摘要

Methods and systems for producing hydrogen from a biomass are disclosed. In some embodiments, the method includes decomposing a biomass to produce an aqueous effluent including nitrogen species, generating ammonia from the nitrogen species, combusting the ammonia in the presence of catalysts to decompose the ammonia to hydrogen and nitrogen, and combusting a portion of the hydrogen and the nitrogen to provide heat for combusting the ammonia. In some embodiments, the system includes a bioreactor for decomposing a biomass to produce an aqueous effluent including nitrogen species, a mechanism for generating ammonia gas from the nitrogen species, a catalytic reforming reactor for converting the ammonia gas to hydrogen gas and nitrogen gas, a combustor for combusting a portion of the hydrogen gas and the nitrogen gas to provide heat for converting the ammonia gas, and a separator for isolating the hydrogen gas.
