Description

Herstellung von Wasserstoff aus Wassergas und Wasserdampf in der Hitze. 1Die bisherige Erzeugung von Wasserstoff aus Wassergas durch Verflüssigung und Abscheidung des Kohlenoxyds verursacht einen bedeutenden Kraftaufwand, weil Kohlenoxyd sich erst bei -i79° verflüssigt.Production of hydrogen from water gas and water vapor in the heat. 1The previous generation of hydrogen from water gas by liquefaction and separation of the carbon dioxide causes a considerable amount of force, because carbon dioxide itself only liquefied at -i79 °.

Das vorliegende Verfahren hat die an sich bekannte Methode zur Grundlage, das Kohlenoxyd zu Kohlensäure zu verbrennen, die sich mit viel weniger Aufwand aus dem Wasserstoff entfernen läßt. Entgegen dem Verfahren nach der amerikanischen Patentschrift 854157 wird jedoch hier Kohlenstaub oder Wassergas mit stickstofffreiem Sauerstoff verbrannt und in die Flamme ein in Wärmespeichern vorher auf 15oo° erhitztes Gemisch von Wassergas und Wasserdampf eingeleitet, wobei sich der Wasserdampf zersetzt und der frei werdende Sauerstoff eine entsprechende Menge des Gemisches verbrennt, so daß es frei von Kohlenoxyd und gleichzeitig durch neugebildetes Wasserstoffgas angereichert wird.The present procedure is based on the method known per se, Burn the carbon dioxide into carbonic acid, which can be made from with much less effort the hydrogen can be removed. Contrary to the method according to the American patent specification However, 854157 becomes coal dust or water gas with nitrogen-free oxygen here burned and in the flame a mixture previously heated to 1500 ° in heat accumulators initiated by water gas and water vapor, the water vapor decomposing and the released oxygen burns a corresponding amount of the mixture, so that it is free of carbon oxide and at the same time enriched by newly formed hydrogen gas will.

Das entstehende Gemisch von Wasserstoff, Kohlensäure und nicht zersetztem Wasserdampf wird abwechselnd durch einen der beiden feuerfesten Wärmespeicher abgeleitet, in dem es seine Wärme abgibt, die dann im Umschalt-Wechselbetrieb an das nachfolgend eingeleitete Wassergas-Wasserdampf-Gemisch wieder übertragen wird und dieses auf 15oo° überhitzt. Wenn beispielsweise ein Gemisch, das 4o Teile Wassergas und 6o Teile Wasserdampf enthält, so weit erhitzt wird, daß die Zersetzung des Wasserdampfes vor sich geht, dann verbrennt der frei werdende, mit 2o Teilen im Wasserdampf enthaltene Sauerstoff die q.o Teile Wassergas zu CO@ und HGO, und es bilden sich q.o Teile neuer Wasserstoff. Ein Wärmeverbrauch findet dabei nur insoweit statt, als etwa der Wärmetausch in. den Wärmespeichern nicht ganz vollkommen vor sich geht und Wärmeverluste nach außen eintreten.The resulting mixture of hydrogen, carbonic acid and undecomposed Water vapor is alternately diverted through one of the two fireproof heat accumulators, in which it gives off its heat, which is then switched over to the following initiated water gas-water vapor mixture is transferred again and this on 15oo ° overheated. For example, if a mixture that contains 4o parts water gas and 6o Contains parts of water vapor, is heated so far that the decomposition of the water vapor goes on, then burns the released, containing 20 parts in the water vapor Oxygen converts the q.o parts of water gas to CO @ and HGO, and q.o parts are formed new hydrogen. A heat consumption takes place only to the extent that about the heat exchange in the heat accumulators is not quite complete and there is heat loss enter outside.

Dieser Abmangel wird durch die Kohlenstaub-Sauerstoff-Zusatzfeuerung ausgeglichen. Das Kohlensäure - Wasserdampf - Wasserstoff f-Gemisch wird nach dem Austritt aus denn Wärmespeicher in einen unter o,2 Atm. Vakuum stehenden Kondensator geleitet, in dem sich der Wasserdampf verflüssigt und dabei eine gleich große Menge Dampf erzeugt, die dann wieder vergast wird. Die Kohlensäure wird in üblicher Weise durch Absorption oder Verflüssigung unter Tiefkühlung abgeschieden, die fehlende Wasserdampfmenge wird aus dem Abdampf einer Dampfkraftanlage zugesetzt.This deficiency is caused by the additional coal dust and oxygen firing balanced. The carbonic acid - water vapor - hydrogen f mixture is after the Exit from then heat storage in a below o, 2 atm. Vacuum standing condenser in which the water vapor is liquefied and in an equally large amount Steam is generated, which is then gasified again. The carbonic acid is produced in the usual way deposited by absorption or liquefaction under freezing, the missing The amount of water vapor is added from the exhaust steam of a steam power plant.

Das vorliegende Verfahren ist gekennzeichnet 1. dadurch, daß in hochfeuerfesten Wärmespeichern mit einer Kohlenstaub- oder Gas-Sauerstoffflamme eine Temperatur von etwa 15oo° aufrechterhalten und abwechselnd durch einen der beiden Wärmespeicher im Umschalt-Wechselbetrieb ein Gemisch von Wassergas und Wasserdampf eingeleitet wird, das sich in diesen im Gegenstrom bis zur Zersetzung des Wasserdampfes erhitzt und wobei der Sauerstoff aus dem zersetzten Wasserdampf das Wassergas in an sich bekannter Weise zu CO" und H20 verbrennt, während gleichzeitig Wasserstoff frei wird und das aus Kohlensäure, Wasserdampf und Wasserstoff bestehende Abgasgemisch seine Wärme an einen der beiden Wärmespeicher überträgt, worauf nachfolgend im Umschalt-Wechselbetrieb die von dem betreffenden Wärmespeicher aufgenommene Abgaswärme wieder an das umzuwandelnde Wassergas-Dampf-Gemisch abgegeben wird: 2. dadurch, daß das Abgas nach dem Austritt aus den Wasserspeichern in einen unter Vakuum gesetzten Verdampfer geleitet wird, in dem sich der Wasserdampf unter erneuter Dampferzeugung verflüssigt.The present method is characterized 1. characterized in that in highly refractory Heat storage with a coal dust or gas oxygen flame a temperature of about 15oo ° and alternately by one of the two heat accumulators a mixture of water gas and water vapor is introduced in changeover mode which is heated in these in countercurrent until the decomposition of the water vapor and wherein the oxygen from the decomposed water vapor contains the water gas in itself known way to CO "and H20 burns while at the same time freeing hydrogen and that from carbonic acid, Existing water vapor and hydrogen Exhaust mixture transfers its heat to one of the two heat accumulators, whereupon subsequently in switch-over operation, the exhaust gas heat absorbed by the relevant heat accumulator is released back to the water gas / steam mixture to be converted: 2. as a result, that the exhaust gas after leaving the water reservoirs in a vacuum Evaporator is passed, in which the water vapor with renewed steam generation liquefied.
