Description

Verfahren zum Vergasen staubförmiger Brennstoffe Die bisher bekannten Versuche, Kohlenstaub zu vergasen, haben noch nicht zu einem technisch brauchbaren Verfahren geführt (vgl. B o u r c o u d , Chemical and Metallurgical Engineering 192i, Band 2,1, Seite 6oo). Das .erzielte Gas besaß einen großen Gehalt an Kohlensäure und enthielt noch-einen bedeutenden Teil des angewandten Kohlenstaubs in Form von Koksstaub. Das geringwertige Gas war kaum für thermische Zwecke zu verwenden, gänzlich unbrauchbar aber für chemische Zwecke, wie Ammoniaksynthese oder Hydrierungen.Process for gasifying pulverulent fuels The previously known Attempts to gasify coal dust have not yet turned into a technically viable one Procedure (see B o u r c o u d, Chemical and Metallurgical Engineering 192i, volume 2.1, page 600). The gas obtained had a high carbonic acid content and still contained a significant part of the applied coal dust in the form of Coke dust. The low-grade gas could hardly be used for thermal purposes, entirely but useless for chemical purposes such as ammonia synthesis or hydrogenation.

Es hat sich nun gezeigt, daß aus staubförmigen Brennstoffen in technisch einfacher Weise hochwertige Gasgemische .erhaltenwerden können, wenn man die Vergasung mittels Sauerstoffs oder Sauerstaff-Luft-Gemischen vornimmt. Die zunächst durch die Entgasung der Kohle freiwerdenden Kohlenwasserstaffe, wie Methan u. dgl., werden dabei praktisch vollständig zerstört, der Kohlensäuregehalt ist nicht hoch und die im Abgas enthaltene Brennstoffstaubmenge gering. Die erhaltenen Gasgemische sind nach erfolgter Entfernung des Kohlenoxyds, etwa durch Umsetzung mittels Wasserdampfs und Absorption der hierbei gebildeten Kohlensäure, infolge ihres hohen Gehalts an Wasserstoff und der Ab-Wesenheit erheblicher Mengen von Kohlenwass.erstoffen für die Ammoniaksynthese und für Hydrierungen verwendbar.It has now been shown that from powdered fuels in technical high-quality gas mixtures. can be obtained simply by using the gasification using oxygen or oxygen-air mixtures. The first through the degassing of the hydrocarbons released by coal, such as methane and the like practically completely destroyed in the process, the carbonic acid content is not high and the The amount of fuel dust contained in the exhaust gas is low. The gas mixtures obtained are after the carbon oxide has been removed, for example by reaction with steam and absorption of the carbonic acid formed thereby, due to its high content of Hydrogen and the absence of substantial amounts of hydrocarbons for the ammonia synthesis and can be used for hydrogenations.

Gegenüber der bekannten Vergasung von stückiger Kohle mittels Sauerstoffs bedeutet das vorliegende Verfahren insofern einen wesentlichen Fortschritt, als hierbei zur Erzielung eines hochwertigen Gases, wozu sonst fast ausschließlich teurer Koks verwendet werden muß, minderwertige Brennstoffe, z. B. Braunkohlenstaub, dienen können. Auch übersteigt der Durchsatz bei weitem den der besten Wassergasgeneratoren. Das hier mögliche ununterbrochene Arbeiten ist ein weiterer besonderer Vorzug des Verfahrens.Compared to the known gasification of lumpy coal by means of oxygen the present method represents a significant advance in that here to achieve a high-quality gas, which is otherwise almost exclusively more expensive Coke must be used, low quality fuels, e.g. B. pulverized lignite, serve can. The throughput also far exceeds that of the best water gas generators. The uninterrupted work that is possible here is another special advantage of the Procedure.

Infolge dieser Vorteile, die eine wesentliche Verbilligung des erzeugten Gases bewirken, ist es wirtschaftlich möglich, Sauerstoff als Vergasungsmittel zu benutzen.As a result of these advantages, a substantial reduction in the price of the produced Effect of gas, it is economically possible to use oxygen as a gasification agent use.
