Description

Verfahren zur Herstellung von Gasreinigungsmasse Bei der bekannten Entschwefelung von Kokerei- oder Leuchtgas unter Verwendung eisenoxydhaltiger Massen sind großflächige Räume erforderlich, da man die Reinigungsmassen infolge des hohen Widerstandes. den diese dem Gasdurchgaiig entgegensetzen. nur in dünnen Schichten ausgebreitet anwenden kann.Process for the production of gas cleaning mass In the known Desulfurization of coke oven gas or coal gas using compounds containing iron oxide Large rooms are required, as the cleaning compounds as a result of the high Resistance. which these oppose the gas permeability. only in thin layers can apply widely.

Man hat diesen Nachteil dadurch zu beseitigen versucht. daß man die Massen brilcettierte. wodurch iedoch die wirksame Oberfläche stark verringert wird. Setzt man zwecks Vergrößerung der Oberfläche den zu brikettierenden Massen auflockernde Mittel, wie Sagespäne, zu. so werden Produkte von ungenügender Festigkeit erhalten.Attempts have been made to eliminate this disadvantage. that one Crowds lit up. which means that the effective surface area is greatly reduced. If one uses loosening masses to be briquetted in order to enlarge the surface Means, like saga chips, too. thus products of insufficient strength are obtained.

Es wurde nun gefunden. daß alle diese Schwierigkeiten behoben werden und man eine ausgezeichnere Gasreinigungsmasse von grober Oberfläche und Festigkeit erhält. wenn man reaktionsfähiges Oxyd enthaltende Massen mit Bindemitteln, wie Zement. z. B. Magnesiazement, Kalk, Gips, in Gegenwart von Alkali- oder Ammoniumcarbonat und wenig Wasser innig vermischt und das Ganze alsdann erwärmt. Durch das Erwärmen, z. B. in einem Wärmeschrank auf 40 bis 50 während einiger Zeit, zersetzt sich das Bicarbonat, wodurch feine Poren in der Masse gebildet werden. die ein vollständiges Abbinden des Zements usw. gestatten. Es genügen meist Mengen von ½ bis 10% Bicarbonat, bezogen auf die Gesamtmasse. Zweckmäßig verwendet man so viel Wasser, wie zur Erzielung eines dikken Breies nötig ist. Die Masse kann in beliebige Formen gebracht und ferner vor oder nach dem Erwärmen in Stücke der gewunschten Größe zerteilt werden. It has now been found. that all these difficulties will be resolved and you get an excellent gas cleaning compound of coarse surface area and strength receives. when one reactive oxide-containing masses with binders, such as Cement. z. B. magnesia cement, lime, gypsum, in the presence of alkali or ammonium carbonate and a little water intimately mixed and then warmed up. By warming z. B. in a heating cabinet to 40 to 50 for some time, the decomposes Bicarbonate, which creates fine pores in the mass. the a complete Allow cement, etc. to set. Quantities of ½ to 10% bicarbonate are usually sufficient, based on the total mass. It is advisable to use as much water as to achieve it a thick porridge is necessary. The mass can be brought into any shape and further be cut into pieces of the desired size before or after heating.

Beispiel 75 gewichtsteile einer eisenoxydhaltigen Masse. wie sie als Rückstand beim Bauxitaufschluß erhalten wird, werden mit 25 Gewichtsteilen Zement und ½ Gewichtsteil Ammoniumbicarbonat gut vermischt und alsdann mit wenig Wasser zu einem dicken Brei angerührt. Dieser wird in flache Formen gegossen und sodann in einem Wärmeschrank etwa ¼ Stunde lang bei 40 erwärmt. Die Masse wird darauf in Stücke gewünschter Größe geschnitten: nach einigem Stehenlassen sind sie vollständig gehärtet und können in Betrieb genommen werden. Sie können lange Zeit zur Gasentschwefelung benutzt werden und halten vielen Extraktionen, z. B. mit Schwefelkohlenstoff. stand. Example 75 parts by weight of a mass containing iron oxide. as is obtained as a residue during the bauxite digestion, 25 parts by weight of cement are added and ½ part by weight of ammonium bicarbonate mixed well and then with a little water mixed into a thick pulp. This is poured into flat molds and then Heated in an oven at 40 for about ¼ hour. The mass is on it in Pieces of the desired size cut: if left standing for a while, they are complete hardened and can be put into operation. You can use gas desulphurisation for a long time are used and hold many extractions, e.g. B. with carbon disulfide. was standing.
