| titleOfInvention | Process for the production of biogas from predominantly starchy raw materials as biomass |
| abstract | Process for the production of biogas from predominantly starch-containing raw materials as biomass by a multi-stage anaerobic conversion by means of wet fermentation as primary fermentation (hydrolysis and acidogenesis) and secondary fermentation (acetogenesis and methanogenesis), in at least two separate fermentation stages operated with different conditions, characterized that a) in the first fermentation stage only biomass at temperatures in the range 40 to 65 ° C, which depend on the TS content of the biomass, supplying a subset of liquid fermentation substrate, which comes from the approach of a previous first fermentation stage and has a temperature is at least as high as the temperature of the first fermentation stage, primarily in compliance with a TS content of less than 15%, is fermented, which is released by spontaneous propagation of the acidophilic bacteria contained in the supplied liquid fermentation substrate heat energy, and parallel to the primary fermentation by means of existing anaerobic bacteria contained in the substrate sulfur and / or ammonia-containing compounds are converted to sulfur and ammonia, and within a residence time of up to two days a carbon dioxide and hydrogen sulfide-rich biogas with a predominant CO 2 content of at least 60 vol .-% and a low Methane content in the n non combustible area arises, b) after completion of the first fermentation stage resulting fermentation substrate is separated into a solid phase and a liquid phase, wherein the solid phase is adjusted to a higher DM content, and the solid phase is subjected in at least one further fermentation stage of a secondary fermentation over a period of at least 7 days , wherein a pH of above 7 sets and on the available carbon sources an oxygen-free and low sulfur and ammonia low biogas is formed with a methane content of about 60 to 85 vol .-%, and c) the biogas obtained in the respective fermentation stages for the recovery of methane are worked up or purified separately. |
