Verfahren zur regenerativen Energiegewinnung durch die Verknüpfung einer Vergärungsanlage für biogen organische Stoffe mit einer Brennstoffzelle

摘要

A process for generating electrical energy by fermentation of biomass has the bio-gases produced during the process removed, conditioned and then passed to a fuel cell. The processing entails removal of sulphurous compounds and interfering gases, followed by enrichment of the methane content. The humidity is also reduced. Heat energy created in the heat cell is passed back to the fermenter and also to the steam reformer. The residue from the fermenter has the humidity reduced by the heat from the fuel cell and/or the reformer. The liquid product of the fermenter is conditioned in the form of an alcohol.
