Description

Verfahren zur Ausführung katalytischer Reaktionen und Absorptionen. Es sind verschiedene Verfahren zur Herstellung von aktiven Kohlen bekannt geworden, die auf thermischer und gegebenenfalls auch chemischer Behandlung von Holz, Braunkohle u. dgl. beruhen.Process for carrying out catalytic reactions and absorptions. Various processes for the production of active carbons have become known, those based on thermal and possibly also chemical treatment of wood, lignite and the like.

Es wurde nun gefunden, daß die kohlehaltigen Verbrennungsrückstände von Braunkohle, wie sie z. B. bei Dampfkesselfeuerung mit Braunkohle oder bei der Staubfeuerung mit Braunkohle oder Braunkohlenkoks in Form von Flugasche anfallen, Produkte darstellen, die die Eigenschaften aktiver Kohlen besitzen, den bekannten aktiven Kohlen sogar noch verschiedene wesentliche Vorteile voraus haben.It has now been found that the carbonaceous combustion residues of lignite, as z. B. with steam boiler firing with lignite or the Dust firing with lignite or lignite coke occurs in the form of fly ash, Represent products that have the properties of active coals, the known ones even have several major advantages over active coals.

Die noch kohlehaltigen Verbrennungsrückstände können, so wie sie anfallen, zur Ausführung katalytischer Reaktionen und von Absorptionen bereits unmittelbar angewandt werden und zeigen hierbei im allgemeinen schon gute Eigenschaften. Man erreicht jedoch eine wesentliche Erhöhung der Wirksamkeit, wenn man eine Anreicherung der in den Verbrennungsrückständen enthaltenen verbrennlichen Bestandteile vornimmt. Dieses kann auf die verschiedenste Weise erfolgen, z. B. durch Siebung oder Windsichtung oder durch fraktioniertes Niederschlagen mittels der Methode der mechanischen oder elektrischen Staubreinigung oder durch chemische Behandlung, wobei die anorganischen Bestandteile zum Teil oder vollständig entfernt werden. Die so erhaltenen Produkte haben hohe absorbierende und katalytische Eigenschaften. Bei der katalytischen Oxydation von Schwefelwasserstoff bieten sie noch den Vorteil, daß sie auch ohne Verwendung von Ammoniak oder Alkalien sehr gut wirksam sind.The still carbon-containing combustion residues can, as they arise, for carrying out catalytic reactions and absorptions already immediately are used and generally show good properties. Man However, it achieves a substantial increase in effectiveness if you get a fortification the combustible components contained in the combustion residues. This can be done in a variety of ways, e.g. B. by sieving or air sifting or by fractional precipitation using the method of mechanical or electrical dust cleaning or chemical treatment, being the inorganic Components are partially or completely removed. The products thus obtained have high absorbing and catalytic properties. In catalytic oxidation of hydrogen sulphide they still offer the advantage that they can be used without use ammonia or alkalis are very effective.

Um den beschriebenen aktiven Massen für Gasreaktionen eine erhöhte Durchlässigkeit zu geben, da sie sonst infolge der geringen Korngröße häufig einen mehr oder minder erheblichen Widerstand bieten, kann man die kohlehaltigen Verbrennungsrückstände unmittelbar oder nach erfolgter Anreicherung oder unter Mischung verschiedener Teile der fraktionierenden Trennung mit Wasser anteigen und in Brikett- oder Pillenform bringen. Man erhält so haltbare Körper, die z. B. ein vorzügliches Füllmaterial für Reaktionstürme bilden.To the described active masses for gas reactions an increased To give permeability, otherwise due to the small grain size they often have a offer more or less considerable resistance, one can use the carbonaceous combustion residues immediately or after enrichment or by mixing different parts after fractional separation, make a paste with water and in briquette or pill form bring. This gives durable bodies that, for. B. an excellent filler material form for reaction towers.
