Abstract
Verfahren zur anaeroben Aufbereitung pflanzlicher und tierischer Biomasse, auch von Abfall, bestehend aus orga nischen Materialien mit relativ hohem Molekulargewicht, bei dem in einem Reaktorraum die hochmolekularen organischen Materialien durch Bakterienstämme in organische Materialien mit niedrigem Molekulargewicht und diese in niedere orga nische Säuren unter Bildung von H ↓2, CO ↓2 und H ↓2S in Essigsäure übergeführt werden, dann die entstehenden Substanzen durch methanbildende Bakterien in CH ↓4 und CO ↓2 umgewandelt werden, wobei in dem oder den Reaktorraum (-räumen) eine Aufteilung von Säurephase und Methanphase vorzugsweise im umgekehrten Verhältnis zu den Abbauraten der Prozeßstufen Säurebildung und Methanbildung erfolgt, wodurch in dem abgeteilten Raum für die Säurephase die abgebauten Produkte nach unten sinken und in den Fermentationsraum für die Methanbildung gelangen, wobei aus der ersten Phase des Verfahrens, der Säurephase, die entstehenden Gase, insbesondere CO ↓2 und H ↓2S, ausgeschieden werden.Process for the anaerobic processing of plant and animal biomass, including waste, consisting of orga African materials with a relatively high molecular weight, in which the high molecular weight organic materials are converted into organic materials with low molecular weight by bacterial strains in a reactor chamber and these into lower organic acids with the formation of H ↓ 2, CO ↓ 2 and H ↓ 2S are converted into acetic acid, then the resulting substances are converted into CH ↓ 4 and CO ↓ 2 by methane-forming bacteria, with the acid phase and methane phase being divided in the reactor chamber (s) preferably in inverse proportion to the degradation rates of the process stages of acid formation and methane formation, whereby the degraded products sink down in the partitioned space for the acid phase and get into the fermentation space for methane formation, the resulting from the first phase of the process, the acid phase Gases, especially CO ↓ 2 and H ↓ 2S, to be excreted.

Das Hauptpatent 31 02 739 betrifft ein Verfahren zur Herstellung von Biogas aus pflanzlicher und tierischer Biomasse, auch von Abfall, gemäß dem Oberbegriff von Anspruch 1.The main patent 31 02 739 relates to a method for Production of biogas from plant and animal biomass, including waste, according to the generic term of Claim 1.
Bei der Speicherung des Biogases können die nur als Ballaststoffe dienenden Gase, wie CO2 und H2, aus Gründen der Raumerfordernisse nicht in dem Biogas verbleiben, und die Energieausbeute würde durch diese Gase vermindert werden. Außerdem würde H2S eine starke Korrosionswirkung im Leitungssystem hervorrufen. When storing the biogas, the gases that only serve as roughage, such as CO2 and H2, cannot remain in the biogas for reasons of space requirements, and the energy yield would be reduced by these gases. In addition, H 2 S would have a strong corrosive effect on the pipe system.
Erfindungsgemäß wurde nun gefunden, daß diese durch das Mitschleppen der Ballastgase entstehenden Nachteile vermieden werden können, wenn aus der Säurephase die entstandenen Gase durch eine Abzugsleitung abgeführt werden. Bei den dort entstandenen Gasen handelt es sich insbesondere um H2S und CO?.According to the invention it has now been found that these result from the entrainment of the ballast gases Disadvantages can be avoided if the gases formed from the acid phase are passed through a discharge line be discharged. The gases produced there are in particular H2S and CO ?.
Die Erfindung betrifft demgemäß auch einen Biore- t>o aktor zur Durchführung des Verfahrens enthaltend eine Einlaßleitung (1) für die zu behandelnde organische Substanz, einen Bereich (4) für die Behandlung der Biomasse mit säurebildenden Bakterien unter Einschluß eines unterhalb liegenden Bereichs (5) für die Essigsäure- b5 bildung, einem damit in offener Verbindung stehenden Bereich (6) für die Methanbildung, wobei das Verhältnis des säure- und essigsäurebildenden Bereichs zu demThe invention accordingly also relates to a Biore- t> o actuator for carrying out the method containing an inlet line (1) for the organic to be treated Substance, an area (4) for the treatment of the biomass with acid-forming bacteria, including a below lying area (5) for the acetic acid b5 education, an openly connected area (6) for methane formation, with the ratio of the acid and acetic acid producing area to the

Besonders vorteilhaft ist es dabei, wenn der Bereich 4 für die Behandlung der Biomasse mit säurebildenden Bakterien und der Bereich 6 für die Methanbildung voll mit Flüssigkeit gefüllt sind. Dies kann dadurch erreicht werden, daß das Flüssigkeitsniveau im Einfall- bzw. Austragsstutzen höher als das übrige Niveau gehalten wird.methane-forming area is 1:10, a gas outlet (2) and an outlet for the degraded biomass, characterized by an outlet line (7) for the gases produced in the area (4).
It is particularly advantageous if the area 4 for the treatment of the biomass with acid-forming bacteria and the area 6 for methane formation are completely filled with liquid. This can be achieved in that the liquid level in the inlet or discharge nozzle is kept higher than the rest of the level.
