Description

Die üblichen und seither bekannt gewordenen Verfahren zum, Reinigen von Gas, das aus Kohlen u. dgl. hergestellt worden ist, ermöglichen nicht die völlige Beseitigung der schwefelhaltigen Bestandteile. Schwefel findet sich im, gereinigten Gas stets noch in wechselnden Mengen, bei Leuchtgas etwa 30 bis 50 g in 100 cbm. in Form von organischen Schwefelverbindungen. Diese kleinen Mengen können zwar bei Verwendung des Gases zum Beleuchten oder Heizen unter Umständen in Kauf genommen werden, wirken aber äußerst störend, wenn das Gas in gewissen chemischen Prozessen weiter verarbeitet werden soll, ja sie können die technische Durchführung solcher Prozesse unmöglich machen.The usual and since then become known method for, cleaning of gas, which from Coals and the like have been produced, do not allow the complete elimination of the sulphurous Components. Sulfur can always be found in the cleaned gas in changing Quantities, with luminous gas about 30 to 50 g in 100 cbm. in the form of organic sulfur compounds. These small amounts can be accepted under certain circumstances if the gas is used for lighting or heating but are extremely disruptive when the gas is involved in certain chemical processes Should be further processed, yes they can technically carry out such processes to make impossible.

Es wurde nun ein Verfahren gefunden, nach welchem man Gasen in einfacher Weise die letzten Reste schwefelhaltiger Verbindungen entziehen kann. Das neue Verfahren besteht darin, daß man das in üblicher Weise vorgereinigte Gas durch feinporöse Kohle von guter Wirksamkeit, wie sie unter anderem durch Verkohlen harter Hölzer und das Verfahren der deutschen Patentschrift 290656 erhalten werden kann, passieren läßt. Eine möglichst vollständige Beseitigung des Schwefelwasserstoffes vor der Reinigung mit Kohle ist nötig, da die Aufnahmefähigkeit der Kohle für dies niedrig siedende und daher schwerer kondensierbare Gas verhältnismäßig gering ist, bzw. seine Adsorption verhältnismäßig tiefe Temperaturen erfordern würde.A method has now been found according to which the last residues of sulfur-containing compounds can be removed from gases in a simple manner can. The new process consists in the gas, which has been pre-cleaned in the usual way through fine-pored charcoal of good effectiveness, such as those caused by charring hard woods and the process of German Patent 290656 can be obtained, lets happen. The most complete removal of the hydrogen sulfide before cleaning with coal is necessary because the capacity of coal for this low-boiling point and therefore more difficult to condense gas is relatively small, or its adsorption would require relatively low temperatures.

Die Adsorption von Gasen und Dämpfen durch feinporöse Kohle verschiedenster Art ist an sich bekannt, aus den vorliegenden Veröffentlichungen läßt sich aber in keiner Weise ein Urteil darüber gewinnen, wie sich poröse Kohle verhält, wenn man sie zur Entschwefelung von Gasen verwendet, ganz besonders ob sie imstande ist, die an sich sehr geringen Reste schwefelhaltiger Stoffe aus bereits gereinigten Gasen völlig zu beseitigen. Daß dies durch das hier beschriebene Verfahren erreicht wird, ist um so überraschender, als das Problem der völligen Entschwefelung von Kohlengasen seit langer Zeit in der mannigfaltigsteil Weise bearbeitet wird und bisher in technisch einwandfreier Weise nicht gelöst ist. Die Anwendung der Kohle zum Reinigen von Kohlengasen geschieht z. B. in der Weise, daß man die Kohle in Zylinder füllt, in denen sie auf einem oder mehreren Siebboden ruht. Die Zylinder können mit einer Heizvorrichtung versehen sein, z. B. mit einem Dampfmantel oder mit eingebauten Heizrohren und zweckmäßig mit einem Kühlwasseranschluß, so daß man nach der Sättigung der Kohle imstande ist, durch Heizen und Hindurchleiten eines Gasstromes das Kondensat auszutreiben und durch darauffolgendes Kuhlen die Kohle wieder auf niedere Temperatur zu bringen und so wieder aufnahmefähig zu machen. Zweckmäßig schaltet man mehrere Zylinder hintereinander und läßt es, um eine sichere Wirkung zu haben, nie so weit kommen, daß auch der zuhinterst in der Reihe befindliche Zylinder gesättigt wird.The adsorption of gases and vapors through fine-pored carbon of various kinds is known per se, but in no way can be derived from the available publications Gain a judgment on how porous coal behaves when used for desulfurization used by gases, especially whether it is capable of removing the very small residues Completely remove sulfur-containing substances from gases that have already been purified. That this through the method described here is achieved is all the more surprising as the problem of Complete desulfurization of coal gases for a long time in the manifold manner is and has not yet been solved in a technically flawless manner. The application the coal for cleaning coal gases happens z. B. in such a way that you get the coal fills in cylinders in which it rests on one or more sieve trays. The cylinders can be provided with a heating device, e.g. B. with a steam jacket or with built-in Heating pipes and expediently with a cooling water connection, so that after saturation the coal is capable of removing the condensate by heating it and passing a stream of gas through it to drive out and by subsequent cooling the coal back to a lower temperature to bring and to make them receptive again. It is advisable to switch several Cylinders in a row and, in order to have a certain effect, never let it get that far, that the cylinder located at the back of the row is also saturated.
