Abstract

The invention relates to bioenergetics, namely to a process for producing biomethane.The process, according to the invention, comprises the anaerobic fermentation in a bioreactor of the biomass containing grains and dispersed manure and/or droppings, with introduction into the biomass of triterpenic saponine escin and the mixture of electrolytic hydrogen and liquefied carbon dioxide. The mixture is introduced by bubbling through the biomass layer. The fermentation is carried out at a pressure of 0.5…1.0 MPa in thermophilic conditions. The electrolytic hydrogen is produced by water electrolysis, carried out in a diaphragm electrolyzer, using nickel cathodes plated with nickel-rhenium, nickel-molybdenum or nickel-tungsten alloys.
