Process and device for the desulfurization of biogas by means of functional substances and hydrogen sulfide degrading microorganisms in the biogas fermenter and biogas fermenter

摘要

In order to provide a process for the desulfurization of biogas, which increases the biogas quality, supports the methane formation process and prolongs the life of a biogas fermenter (10), it is proposed that during the anaerobic fermentation of biomass in a biogas digester (10) in a gas space (12) above a substrate system (14) a receiving system (11) is arranged, which is filled with biodegradable carrier bodies (17) which are inoculated with hydrogen sulfide degrading microorganisms and / or for settlement of hydrogen sulfide degrading microorganisms, that the biogas formed by the fermentation the receiving system (11) flows through the carrier bodies (17), wherein this is desulfurized by the microorganisms, and in that in the gas space (12) air is introduced. In addition, a device for desulfurization and a biogas fermenter (10) are described.
