Description
Behandlung von kohlenwasserstoffhaltigem Reduktionsgas Der dem vorliegenden Verfahren der Herstellung von Reduktionsgas für das Eisenwasserdampfverfahren durch Kohlenwasserstoffspaltung zu Grunde liegende Gedanke besteht darin, die Reduktionswirkung des kohlenwasserstoffhaltigen Reduktionsgases zu steigern, ohne dabei bis zur Bildung @ an Kohlensäure zu gehen. Das Reduktionsgas wird dabei zu Erhöhung seines Kohlenoxyd-und Wasserstoffgehaltes und Aufspaltung der Kohlenwasserstoffe vor seiner Verwendung im Wasserstofferzeuger unter gleichzeitigem Zusatz von Wasserdampf durch einen (über 7oo°) erhitzten Raum geführt. Es hat sich dabei herausgestellt, daß der hohe Gehalt des Reduktionsgases an Wasserstoff und Kohlenoxyd wesentlich für eine gute Reduktionswirkung auf das Eisengut ist. Es kommt also bei vorliegendem Verfahren darauf an, ohne Verwendung von Katalysatoren, wie Nickel u. dgl., zu arbeiten und ein CO und H. angereichertes Reduktionsgas zu erzielen.Treatment of hydrocarbon-containing reducing gas of the present Process for the production of reducing gas for the iron water vapor process The idea underlying hydrocarbon splitting consists in the reduction effect of the hydrocarbon-containing reducing gas without thereby up to the formation @ to go to carbon dioxide. The reducing gas is used to increase its carbon dioxide and Hydrogen content and splitting of the hydrocarbons before its use in the hydrogen generator with simultaneous addition of steam by a (via 7oo °) heated room. It turned out that the high salary of the reducing gas of hydrogen and carbon oxide is essential for a good reducing effect on the iron goods. So it depends in the present method, without use of catalysts such as nickel and the like to work and a CO and H. enriched To achieve reducing gas.
Wenn es auch bereits bekannt ist, das Reduktionsgas vor seinem Eintritt in den Wasserstofferzeuger vorzuwärmen, soweit eine Wärmewiedergewinnung der abziehenden heißen Gase möglich ist, und dem kohlenwasserstoffhaltigen Reduktionsgas beim Eintritt in den Wasserstofferzeuger Wasserdampf -zuzusetzen, so kommt im ersteren Falle lediglich eine Wärmegewinnung in Frage und im zweiten Falle die Verhütung von Kohlenstoffabl.agerungen,während bei dem Verfahren gemäß der vorliegenden Erfindung die Erhitzung des Reduktionsgases über 7oo° erfolgen soll zur Umwandlung dieses Gases in ein solches von stärkerer reduzierender Wirkung, wobei diese Umwandlung dadurch beschleunigt werden kann, daß der von dem Gaswasserdampfgemenge durchstrichene heiße Raum mit die Aufspaltung fördernden Stoffen, Eisenstücken, Steinbrocken u. dgl., angefüllt wird.Even if it is already known, the reducing gas before it enters to preheat in the hydrogen generator, as far as a heat recovery of the withdrawing hot gases is possible, and the hydrocarbon-containing reducing gas on entry To add water vapor to the hydrogen generator, in the former case only occurs a heat recovery in question and in the second case the prevention of carbon deposits while in the method according to the present invention, the heating of the reducing gas over 700 ° should be done to convert this gas into a stronger one reducing effect, whereby this transformation can be accelerated, that the hot space traversed by the gas-water vapor mixture is also responsible for the splitting promoting substances, pieces of iron, lumps of stone and the like., is filled.
Bei dem Durchleiten des Reduktionsgases durch den heißen Raum unter gleichzeitiger Zufuhr von Wasserdampf findet ein Aufspalten der Kohlenwasserstoffe in Kohlenstoff und Wasserstoff statt. Der Wasserdampf reagiert mit dem ausgeschiedenen Kohlenstoff unter Bildung von Wassergas. Die Folge der beiden nebeneinander verlaufenden Reaktionen ist eine Vermehrung des Gehaltes des Reduktionsgases an Kohlenoxyd und Wasserstoff sowie die Vermeidung von Kohlenstoffablagerung bei Verwendung dieses Gases im Wasserstofferzeuger.When passing the reducing gas through the hot space below simultaneous supply of water vapor breaks down the hydrocarbons in carbon and hydrogen instead. The water vapor reacts with the excreted Carbon with formation of water gas. The result of the two running side by side Reactions is an increase in the carbon dioxide and carbon content of the reducing gas Hydrogen as well as avoiding carbon deposition when using it Gas in the hydrogen generator.
