Description

Verfahren zur thermischen Umformung von kohlenwasserstoffhaltigen Gasen, von gasförmigen Kohlenwasserstoffen und zur Ulvergasung Es ist ein Verfahren zur thermischen Spaltung und Umformung von kohlenwasserstoffreichen Gasen, auch von solchen, welche kohlenstoffreiche Kohlenwasserstoffe enthalten, sowie auch von gasförmigen reinen Kohlenwasserstoffen und zur Ölvergasung vorgeschlagen worden, bei dem durch Rückführung von im Prozeß gewonnenem Gas die Konzentration der Kohlenwasserstoffe auf zumindest Koksofengaskonzentration verdünnt und diese Mischung dem Spaltungs- und Umformungsprozeß unterworfen wird. Die vorliegende Erfindung betrifft eine Verbesserung dieses Verfahrens und beschäftigt sich mit der thermischen Umformung von kohlenwasserstoffhaltigen Gasen, von gasförmigen Kohlenwasserstoffen und zur Ölvergasung, bei dem Wärmeaustauscher der Bauart und Betriebsart von Cowpern benutzt werden, in welchen die für die Umformung erforderliche Wärme gespeichert und durch ein, gasförmiges Trägermittel dem Prozeß zugeführt wird. Die Erfindung hat erkannt, daß bei Verwendung derartiger Cowper eine rußfreie Umformung auch so durchgeführt werden kann, daß das umzuformende Gas ganz oder teilweise von der Auf'heizung im Cowper ausgeschlossen und für sich auf Temperaturen unterhalb der Rußbildungstemperatur erhitzt sowie als Wärmeträger an Stelle des umzuformenden Gases ein kohlenwasserstofffreies Gas benutzt wird. Bei dem erfindungsgemäßen Verfahren werden die Cowper vor dem Umformungsprozeß mit der Wärme beladen, die nach stöchiometrischen Berechnungen für den Umformungsprozeß einer bestimmten :Menge an Kohlenwasserstoffen erforderlich ist. Verwendet man dann eine solche Menge an kohlenwasserstofffreien Gasen als Wärmeträger, wie sie den umzuformenden Kohlenwasserstoffen stöchiometrisch zurückgeführt werden muß, so wird die Rußbildung vermieden.Process for the thermal reshaping of hydrocarbon-containing Gases, of gaseous hydrocarbons and for Ulvergasung It is a process for thermal cleavage and transformation of hydrocarbon-rich gases, too of those containing carbon-rich hydrocarbons, as well as of gaseous pure hydrocarbons and for oil gasification have been proposed, in the case of the gas obtained in the process by recycling, the concentration of hydrocarbons diluted to at least coke oven gas concentration and this mixture to the cleavage and is subjected to deformation process. The present invention relates to an improvement this process and deals with the thermal transformation of hydrocarbon-containing Gases, from gaseous hydrocarbons and for oil gasification, in the heat exchanger the type and mode of operation of Cowpern are used in which the for the forming required heat is stored and supported by a gaseous carrier medium is fed. The invention has recognized that when using such cowper a soot-free reshaping can also be carried out in such a way that the gas to be reshaped completely or partially excluded from the heating in the Cowper and for yourself Temperatures below the soot formation temperature and as a heat transfer medium Instead of the gas to be transformed, a hydrocarbon-free gas is used. at the inventive method, the Cowper before the forming process with the Heat loaded according to stoichiometric calculations for the forming process a certain: amount of hydrocarbons is required. If you then use such an amount of hydrocarbon-free gases as heat transfer media as they do the hydrocarbons to be converted must be returned stoichiometrically, so will the formation of soot avoided.

Als kohlenwasserstofffreies Gas wird man im allgemeinen eigenerzeugtes umgeformtes Gas benutzen, d. h. wie bei dem eingangs erwähnten Vorschlag mit Wälzgas arbeiten. Es empfiehlt sich, Wasserdampf als 'Vergasungsmittel und Produktionsgas als Wärmeträger in Wärmeaustauschern aufzuheizen, das umzuformende Gas und Teile des als Sauerstoffträger dienenden Vergasungsmittels getrennt vorzuwärmen und die genannten Gase in einem besonderen Raum zur Reaktion zu bringen. Dabei kann die thermisch-chemische Umformung der Gase in einer Wirbelbrennkammer (Zyklonbrenner) vorgenommen werden.As a hydrocarbon-free gas, one is generally self-generated use transformed gas, d. H. as with the proposal mentioned at the beginning with tumble gas work. It is advisable to use water vapor as the 'gasifying agent and production gas as a heat transfer medium in heat exchangers to heat the gas and parts to be transformed to preheat the gasifying agent serving as an oxygen carrier separately and the to bring said gases to reaction in a special room. The thermal-chemical transformation of the gases in a vortex combustion chamber (cyclone burner) be made.
