Description

Verfahren zum Regenerieren von aktiver Kohle Die -Erfindung bezieht sich auf ein Verfahren zur Regenerierung von aktiver Kohle, deren Adsorptionsleistung nach wiederholtem Erhitzen .züm Austreiben der absorbierten Kohlenwasserstoffe herabgesetzt ist. Es sammeln-sich allmählich in der Kohle harzartige Unre'inigkeiten an und setzen die Leistung derselben erheblich herab.Process for Regenerating Active Coal The invention relates focus on a process for the regeneration of active coal, its adsorption capacity reduced after repeated heating .zum expelling the absorbed hydrocarbons is. Resin-like impurities gradually collect and settle in the coal the performance of the same considerably degrades.

Gemäß der Erfindung erfolgt die Regenerierung der Kohfe; durch deren Druckhydrierung, d. h: durch Behandlung derselben mit Wasserstoff unter hohem -Druck und hoher Temperatur, nachdem die Kohlenwasserstoffe aus ihr abgetrieben worden sind. Hierbei kann es außerdem vorteilhaft seih, .wenn ein Katalysator gegenwärtig ist.According to the invention, the coal is regenerated; through their Pressure hydrogenation, d. h: by treating them with hydrogen under high pressure and high temperature after the hydrocarbons have been expelled from it are. It can also be advantageous here if a catalyst is present is.

Man hat bereits vorgeschlagen, bei der Herstellung von aktiver Kohle. die im Schwelprodukt noch enthaltenen teerartigen. Verunreinigungen durch Erhitzen der Kohle in Gegenwart von -Wasserstoff zu beseitigen. Dabei hat man jedoch verhältnismäßig nicht sehr--hohe Temperaturen und keinen Überdruck angewendet. , Ferner hat man vorgeschlagen, - aktive Kohle durch überhitzten Dampf .zu regenerieren, und zwar unter Vermeidung von direkter Erhitzung. - Die angewendeten Temperaturen waren mäßig bzw. gering: Mit Hilfe von mäßig erhitztem Kohlendioxyd oder vielleicht Stickstoff, Wasserstoff, Helium wurde dann die bereits regenerierte Kohle vom Dampf befreit und getrocknet. Beide Verfahren sind im Vergleich zum Erfindungsgegenstand langwierig und von schwacher Wirkung.It has already been suggested in the manufacture of active charcoal. the tarry ones still contained in the smoldering product. Impurities from heating to remove the coal in the presence of hydrogen. In doing so, however, you have to be proportionate not very - high temperatures and no overpressure applied. , Furthermore, one has proposed to regenerate active charcoal through superheated steam, namely while avoiding direct heating. - The temperatures used were moderate or low: With the help of moderately heated carbon dioxide or perhaps nitrogen, Hydrogen, helium then the already regenerated coal was freed from steam and dried. Both methods are lengthy compared to the subject matter of the invention and of weak effect.

Schließlich ist es bekannt, schwere Öle u. dgl. durch Hydrierung unter Druck in der Weise in leicht flüchtige Stoffe oder Öle umzuwandeln, daß man die Flüssigkeit zusammen mit einem Adsorptionsmittel in Gegenwart von Wasserstoff hoher Temperatur und hohem Druck unterwirft. Bei diesem Hydrierverfahren, bei dem auch schon ein Katalysator verwendet wurde, hat man aber die Regenerierung der durch den Hydrierprozeß unbrauchbar gewordenen Adsorptionsmittel lediglich durch Erhitzung vorgenommen.Finally, it is known to subject heavy oils and the like by hydrogenation To convert pressure into volatile substances or oils in such a way that the Liquid together with an adsorbent in the presence of hydrogen higher Subject to temperature and high pressure. In this hydrogenation process, in which too a catalyst has already been used, but one has to regenerate the through the adsorbent which has become unusable in the hydrogenation process is only due to heating performed.

Erfindungsgemäß soll .die Hydrierung bei Drucken von zoo bis. 250 atii und bei Temperaturen von ungefähr 440 bis 4500 C vorgenommen werden. Die Behandlung kann mit Unterbrechungen oder ununterbrochen erfolgen. Als Katalysator kann man z. B. Molybdänsäure zusetzen. Die harzartigen Umeinigkeiten werden in ein Gemisch von flüchtigrn flüssigen Kohlenwasserstoffen umgewandelt.According to the invention. The hydrogenation at pressures from zoo to. 250 atii and at temperatures of approximately 440 to 4500 C. Treatment can be intermittent or uninterrupted. As a catalyst you can, for. B. add molybdic acid. The resinous disagreements are converted into a mixture of volatile liquid hydrocarbons.

Die Regenexierupg erfolgt durch Druckhydrierung nach der Abtreibung des adsorbierten Gases, also z. B. des Benzols. Hierbei. ist die Überwachung der Temperatur wichtig, da bei zu. hoher Temperatur die Harzbildung begünstigt werden kann. Durch Versuche wurde festgestellt, daß eine Temperatur von 5oo° C nicht überschritten werden darf, wenn die besten Resultate erhalten werden sollen.Regeneration takes place through pressure hydration after the abortion of the adsorbed gas, e.g. B. of benzene. Here. is monitoring the Temperature is important because it is too. high temperature the resin formation are favored can. Through trials it was found that a temperature of 500 ° C must not be exceeded if the best results are obtained should.
