Abstract
Description
Es ist bekannt, daß bestimmte Organismen (Algen) mit Hilfe der Photosynthese Kohlenhydrate produzieren. Diese Kohlenhydrate werden teilweise auch extrazellulär angereichert. Weiterhin ist auch allgemein bekannt, daß gewisse Bakterienarten unter Stickstofflimitierung aus Kohlenhydraten molekularen Wasserstoff produzieren [Barclay, W. R., A., L. R. "Microalgal polysaccharide production for the conditioning of agricultural soils." Plant and Soil 88: 159-169; Kamen, M. D., H., G. "Evidence for nitrogenase system in the photosynthetic bacterium Rhodospirillum rubrum." Science 109 (1949): 560].It is known that certain organisms (algae) produce carbohydrates with the help of photosynthesis. Some of these carbohydrates are also enriched extracellularly. Furthermore, it is also generally known that certain types of bacteria produce molecular hydrogen from carbohydrates under nitrogen limitation [Barclay, WR, A., LR "Microalgal polysaccharide production for the conditioning of agricultural soils." Plant and Soil 88 : 159-169; Kamen, MD, H., G. "Evidence for nitrogenase system in the photosynthetic bacterium Rhodospirillum rubrum." Science 109 ( 1949 ): 560].
Ein Verbund beider Organismen in einem Reaktor zur kontinuierlichen Produktion von Wasserstoff existiert zur Zeit nicht.A combination of both organisms in one reactor for the continuous production of Hydrogen does not currently exist.
Die im Patentanspruch 1 angegebenen Erfindung soll erreichen, daß die Kohlenhydrate, die von den Algen produziert werden1 (Möglich wäre auch die Nutzung von kohlenhydratreichen Abwässern.), den Bakterien und das von den Bakterien gebildete Kohlendioxid den Algen zugeführt wird.The invention specified in claim 1 is to achieve that the carbohydrates that are produced by the algae 1 (it would also be possible to use carbohydrate-rich wastewater), the bacteria and the carbon dioxide formed by the bacteria is supplied to the algae.
Durch diesen Verbund wird erreicht, daß unter Ausnutzung der Sonnenenergie, der Wasserstoff regenerativ erzeugt wird.This network ensures that, taking advantage of solar energy, the Hydrogen is generated regeneratively.
Eine vorteilhafte Ausgestaltung der Erfindung ist im Patentanspruch 2 angegeben. Die Zurückhaltung der jeweiligen Organismen durch Filtersysteme erlaubt eine kontinuierliche Betriebsweise des Reaktors und der Austausch des Kohlendioxids eine Steigerung der Photosynthese der Algen.An advantageous embodiment of the invention is specified in claim 2. The Restraint of the respective organisms through filter systems allows a continuous Operation of the reactor and the exchange of carbon dioxide an increase in Algae photosynthesis.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung 1 dargestellt und wird im folgenden näher beschrieben.An embodiment of the invention is shown in the drawing 1 and is in following described in more detail.
Der Verbundreaktor besteht aus zwei Kammern (K 101/K 102). In der Kammer K 101 befinden sich die flüssige Phase der Algen. Mit der oxygenen Photosynthese produzieren die Algen Kohlenhydrate und Sauerstoff. Für die Photosynthese benötigen sie Licht, Kohlendioxid und anorganische Verbindungen. Als Lichtquelle wird das Sonnenlicht genutzt, das Kohlendioxid entstammt aus der Umgebungsluft und der Bakterien kammer (K 102). Die anorganischen Verbindungen werden als Lösung vorgelegt. Die produzierten Kohlenhydrate liegen zum Teil auch extrazellulär, also in der Lösung vor. Die kohlenhydratreiche Lösung (Strom 3) wird über eine Pumpe (P 101) und einen/mehrere Filter zur Kammer K 102 geleitet. Die Filter (F 101) trennen die Algen von der Lösung ab, so daß sich in der Kammer K 102 keine Algen ansammeln können. F 101 wird mit dem Rückstrom aus der Kammer K 102 kontinuierlich gespült, damit der gebildete Filterkuchen nicht zu groß wird. Der gefilterte Strom (Strom 4) spült den Filter F 102 und gelangt schließlich in die Kammer K 102 (Strom 5). Dort setzen die Bakterien die Kohlenhydrate mit Hilfe von Licht und unter Stickstofflimitierung zu Wasserstoff und Kohlendioxid um. Wasserstoff und Kohlendioxid gasen aus (Strom 6). Die Zusammensetzung des Gasgemisches liegt bei ca. 90% H2 und ca. 10% CO2. Der größte Teil des produzierten Kohlendioxids liegt gelöst vor. Diese CO2-haltige Lösung (Strom 7) wird über die Pumpe (P 102) und einen/mehrere Filter zur Kammer K 101 geleitet. Filter F 102 filtert die Bakterien aus der Lösung heraus. Er wird mit dem Strom 4 kontinuierlich gespült. Der Strom 9 spült nun wiederum den Filter F 101 und gelangt schließlich (Strom 10) in die Kammer K 101.The composite reactor consists of two chambers (K 101 / K 102). Chamber K 101 contains the liquid phase of the algae. With oxygenic photosynthesis, the algae produce carbohydrates and oxygen. They require light, carbon dioxide and inorganic compounds for photosynthesis. Sunlight is used as the light source, the carbon dioxide comes from the ambient air and the bacteria chamber (K 102). The inorganic compounds are presented as a solution. Some of the carbohydrates produced are also extracellular, i.e. in the solution. The carbohydrate-rich solution (stream 3 ) is fed to chamber K 102 via a pump (P 101) and one / more filters. The filters (F 101) separate the algae from the solution so that no algae can accumulate in the chamber K 102. F 101 is continuously rinsed with the backflow from chamber K 102 so that the filter cake formed does not become too large. The filtered stream (stream 4 ) rinses the filter F 102 and finally arrives in the chamber K 102 (stream 5 ). There the bacteria convert the carbohydrates into hydrogen and carbon dioxide with the help of light and with nitrogen limitation. Hydrogen and carbon dioxide gas out (stream 6 ). The composition of the gas mixture is approx. 90% H 2 and approx. 10% CO 2 . Most of the carbon dioxide produced is in solution. This CO 2 -containing solution (stream 7 ) is passed to the chamber K 101 via the pump (P 102) and one / more filters. Filter F 102 filters the bacteria out of the solution. It is continuously flushed with stream 4 . Stream 9 in turn rinses filter F 101 and finally (stream 10 ) enters chamber K 101.
Da das Sonnenlicht als Energielieferant genutzt wird, kommt es zu einer Erwärmung der Kammern. Die maximalen Betriebstemperaturen der Algen und Bakterien liegen zwischen 30°C und 45°C. Eine Kühlung ist somit zwingend erforderlich. Die Wärmetauscher WT 101 und WT 102 kühlen die Kammern K 101 und K 102. Die Abwärme kann anderweitig genutzt werden.Since the sunlight is used as a source of energy, the chambers are heated. The maximum operating temperatures of the algae and bacteria are between 30 ° C and 45 ° C. Cooling is therefore imperative. The heat exchangers WT 101 and WT 102 cool the chambers K 101 and K 102. The waste heat can be used for other purposes.
Es existieren Bakterienarten, die sehr empfindlich auf Sauerstoff reagieren. Wenn diese Organismen zum Einsatz kommen, muß der Sauerstoff aus der Algenlösung herausgelöst werden, bevor er zu den Bakterien gelangt. Dies kann durch verschiedene Membranverfahren erfolgen.There are types of bacteria that are very sensitive to oxygen. If those If organisms are used, the oxygen must be released from the algae solution before it gets to the bacteria. This can be done through various Membrane processes are carried out.
Nach einer gewissen Zeit müssen den Algen anorganische Substrate zugeführt werden. Die Bakterien benötigen nur Stickstoff, der z. B. durch kurzzeitiges Begasen mit Luft (in der Nachtphase) geliefert werden kann.After a certain time, inorganic substrates must be added to the algae. The bacteria only need nitrogen, the z. B. by briefly gassing with air (in the night phase) can be delivered.
