Vorliegende Erfindung bezieht sich auf ein Verfahren zur Herstellung einer Masse, welche bei der Sauerstofferzeugung aus atmosphärischer Luft unter Benutzung von Alkalimanganat und Behandlung des letzteren durch Erhitzung mit Wasserdampf als Ausgangsproduct Verwendung finden soll.The present invention relates to a method of making a mass which in the production of oxygen from atmospheric air using alkali manganate and treatment of the latter by heating with steam as the starting product should find.
Eine derartige Masse, deren wesentlichen Bestandtheil das Alkalimanganat bildet, mufs zwecks energischer Einwirkung der heifsen Luft und der erhitzten Dämpfe bei der Sauerstoffgewinnung möglichst porös sein, und es darf diese Masse zu demselben Zweck trotz der Einwirkung des Wasserdampfes nie schmelzen.Such a mass, the essential part of which is the alkali manganate, must for the purpose of energetic action of the hot air and the heated vapors in the production of oxygen be as porous as possible, and this mass must never melt for the same purpose in spite of the action of the water vapor.
Um letzteres zu verhindern, wird dem Alkalimanganat überschüssiges Aetzalkali zugesetzt, so dafs dieses Alkali die selbst durch den überhitzten Dampf immer noch mitgeführte Feuchtigkeit aufsaugt, somit ein Ankleben der Masse an die Retortenwandung verhindert und gleichzeitig infolge dessen das Schmelzen verzögert. To prevent the latter, excess caustic alkali is added to the alkali manganate, so that this alkali still carries with it even the superheated steam Absorbs moisture, thus preventing the mass from sticking to the retort wall and at the same time as a result of this delays the melting.
Zur Herbeiführung der Porosität wird die Masse auf folgende Weise behandelt:To achieve porosity, the mass is treated in the following way:
Man rührt das im Handel befindliche Natriummanganat mit Wasser zu einem dicken Brei an, nachdem man in diesem Wässer vorher 5 bis 8 pCt. kaustische Soda gelöst hat.The commercially available sodium manganate is stirred with water to form a thick one Mash, after 5 to 8 pCt. caustic soda has dissolved.
Dieser Brei wird in eine Retorte gebracht, welche einen Siebboden und unter demselben noch einen weiteren Raum besitzt. Letzterer wird langsam erwärmt, so dafs die in dem Brei enthaltene Feuchtigkeit zur Verdampfung gelangt. An die am oberen Ende verschlossene Retorte wird dann eine Pumpe angesetzt, vermittelst welcher der Dampf vollständig abgesaugt wird, so dafs keine Feuchtigkeit in der langsam erwärmten Masse zurückbleibt.This pulp is placed in a retort which has a sieve bottom and under it owns another room. The latter is slowly warmed up, so that those in the Moisture contained in the pulp evaporates. To the one closed at the top A pump is then attached to the retort, by means of which the steam is completely extracted so that no moisture remains in the slowly heated mass.
Ist die gesammte Feuchtigkeit abgesaugt, so wird der unter dem Siebboden befindliche Raum der Retorte mit der Aufsenluft in Verbindung gesetzt und die Erhitzung gesteigert, während gleichzeitig die Pumpe abgestellt und die Retorte an ihrem oberen Ende geschlossen wird. - Auf diese Weise dringt also die Luft in die Masse ein, und zwar unter dem Druck einer Atmosphäre. Diese unter geringem Druck eintretende Luft veranlafst eine feine Porenbildung innerhalb der Masse, welche immer stärker er- ' hitzt wird.Once all of the moisture has been sucked off, what is under the sieve bottom becomes The space of the retort is connected to the outside air and the heating is increased, while at the same time the pump is switched off and the upper end of the retort is closed will. - In this way the air penetrates the mass, under the pressure of a The atmosphere. This air, which enters under low pressure, causes fine pore formation within the mass, which is heated more and more.
Die Retorte wird so lange erhitzt, bis die Wandung Rothglut annimmt, wobei ein Schmelzen nicht zu befürchten ist, da sich in der Masse keine Feuchtigkeit mehr befindet.The retort is heated until the wall takes on red embers, with a Melting is not to be feared, as there is no longer any moisture in the mass.
Es empfiehlt sich übrigens, die Luft zu trocknen und ihr den Kohlensäuregehalt zu benehmen; ersteres, um eine Wiederzuführung der Feuchtigkeit, und letzteres, um die Bildung von Permanganaten zu verhindern.Incidentally, it is advisable to dry the air and add the carbonic acid content to it behavior; the former to re-supply the moisture, and the latter to the formation to prevent permanganates.
Die so hergestellte Masse ist zur Sauerstoffgewinnung vorzüglich geeignet, da zunächst deshalb ein Schmelzen nicht zu befürchten ist, weil bei der Herstellung der Masse eine Temperatur verwendet worden ist, welche derjenigen bei der Gewinnung mindestens gleichkommt. Fernerhin kann der Wasserdampf, welcher bei der Sauerstoffgewinnung zur Einwirkung gelangt, die Schmelzbarkeit des Ge-The mass produced in this way is excellently suited for the production of oxygen, since initially Melting is therefore not to be feared, because there is a temperature in the manufacture of the mass has been used, which is at least equal to that in the extraction. Furthermore, the water vapor, which is used in the oxygen production for action reached, the meltability of the
misches nicht befördern, da seine Feuchtigkeit durch das überschüssige Alkali absorbirt wird und deshalb ein Ankleben der Masse an die Retorte und dadurch gesteigerte Schmelzbarkeit nicht zu befürchten ist. Dabei ermöglichen die Poren der heifsen Luft und dem Wasserdampf ein Hineintreten in sämmtliche Theilchen der Masse.do not convey the mixture, as its moisture is absorbed by the excess alkali and therefore a sticking of the mass to the retort and thus increased meltability is not to be feared. The pores allow the hot air and water vapor a step into all the particles of the mass.
