Description

Verfahren zur Erzeugung von Kohlenoxyd und Wasserstoff durch Brennstoffvergasung Ausgangsstoffe für eine ganze Reihe synthetisch hergestellter Verbindungen sind Kohlenoxyd und Wasserstoff. Als eine der wirtschaftlichsten Arten ihrer Herstellung hat sich der Weg über die Vergasung erwiesen. Zweckmäßig verwendet man hierbei an Stelle der sonst üblichen Luft reinen Sauerstoff. Dadurch wird nicht allein der große Ballast an Stickstoff vermieden, sondern auch die Reaktionszeit erheblich verkürzt und dadurch der Durchsatz des Generators gesteigert. Um die Temperatur im Gaserzeuger nicht zu hoch ansteigen zu lassen, wird dem Sauerstoff Wasserdampf oder Kohlensäure beigemischt, deren Zersetzung eines erheblichen Wärmeaufwandes bedarf.Process for the production of carbon monoxide and hydrogen by fuel gasification Are starting materials for a whole range of synthetically produced compounds Carbon dioxide and hydrogen. As one of the most economical ways of their production the way on gassing has turned out. Appropriately, one uses here Instead of the usual air, pure oxygen. This is not just the large nitrogen ballast is avoided, but the reaction time is also considerable shortened and thereby the throughput of the generator increased. About the temperature If you do not allow the gas generator to rise too high, the oxygen becomes water vapor or carbonic acid is added, the decomposition of which requires a considerable amount of heat requirement.

Je nach der Menge des dem Generator zugeführten Wasserdampfes lassen sich Gleichgewichtsbedingungen schaffen, bei denen in dem erzeugten Gas der Gehalt an Kohlenoxyd und Wasserstoff in weiten Grenzen schwankt.Release depending on the amount of water vapor supplied to the generator create equilibrium conditions in which in the gas produced the content of carbon monoxide and hydrogen fluctuates within wide limits.

Die Erfindung schlägt nun vor für den Fall, daß Kohlenoxyd und Wasserstoff in Mengenverhältnissen herzustellen sind, die sich in einem einzigen Generator nicht erzielen lassen, die Erzeugung des Kohlenoxyds getrennt von der des Wasserstoffes vorzunehmen, und zwar in einem zweiten Generator. Nach dem vorgeschlagenen Verfahren wird der Brennstoff in einem Gaserzeuger mit einem sehr hochgesättigten Wasserdampfsauerstoffgemisch vergast, wobei der Wasserstoffgehalt des Gases tunlichst einen Höchstwert erreicht. Das Gas besteht dann noch aus einer geringen Menge Kohlenoxyd und aus einer großen Menge Kohlensäure. Die Kohlensäure wird aus dem Gas, beispielsweise durch Auswaschen unter Druck, entfernt und zusammen mit Sauerstoff einem zweiten Gaserzeuger zugeführt. Dort wird ein fast nur aus Kohlenoxyd bestehendes Gas erzeugt; der Rest ist Kohlensäure, die, falls erforderlich, gleichfalls entfernt werden und dem Prozeß wieder zugeführt werden kann.The invention now proposes for the case that carbon dioxide and hydrogen are to be produced in proportions that cannot be found in a single generator can achieve the production of carbon dioxide separately from that of hydrogen in a second generator. According to the proposed procedure is the fuel in a gas generator with a very highly saturated water vapor-oxygen mixture gasified, whereby the hydrogen content of the gas reaches a maximum value as far as possible. The gas then consists of a small amount of carbon monoxide and a large one Amount of carbonic acid. The carbon dioxide is extracted from the gas, for example by washing it out under pressure, removed and fed to a second gas generator together with oxygen. A gas consisting almost entirely of carbon monoxide is produced there; the rest is carbonic acid, which, if necessary, are also removed and fed back into the process can be.

Die Wirtschaftlichkeit des Verfahrens wird besonders dadurch gewährleistet, daß die bei der Wasserstoffherstellung in dem einen Gaserzeuger gewonnene Kohlensäure nicht verlorengeht, sondern in wirtschaftlicher Weise in einem zweiten Gaserzeuger zur Herstellung von Kohlenoxyd verwandt wird.The economic efficiency of the process is particularly guaranteed by that the carbonic acid obtained in the production of hydrogen in one gas generator is not lost, but in an economical way in a second gas generator is used for the production of carbon monoxide.
