Description

Verfahren zur Erhöhung der Sauerstoffausbeute aus Mischungen von Chemikalien Es ist bekannt, Sauerstoff aus Stoffen herzustellen, welche nach der Erhitzung Sauerstoff abspalten. Als sauerstoffabgebende Chemikalien werden vorwiegend Chlorate, Perchlorate oder Nitrate verwendet, welchen brennbare organische oder anorganische Substanzen in solchen :Mengen zugetnischt werden, daß eine völlige Zersetzung des an einer Stelle örtlich erhitzten Gemisches gewährleistet wird.Process for increasing the oxygen yield from mixtures of chemicals It is known to produce oxygen from substances which, after heating, are oxygen split off. Chlorates and perchlorates are mainly used as oxygen-releasing chemicals or nitrates, which are flammable organic or inorganic substances in such: quantities are added that a complete decomposition of the one Place locally heated mixture is guaranteed.

Als die Verbrennung unterhaltende organische Körper sind Kohlenstoff, kohlenwasserstoffhaltige Substanzen sowie Harze, als anorganische Körper Mittel wie Eisen oder Kupfer sowie Silicium und Metalle in Form von Legierungen vorgeschlagen worden. Der Zusatz von brennbaren Bestandteilen, welcher zur Erreichung der Zersetzungstemperatur der sauerstoffabgebenden Mittel nötig ist, bringt den Nachteil mit sich, daß die Ausbeute an Sauerstoff herabgesetzt wird, da die verbrennenden Stoffe zu ihrer Verbrennung einen Teil des Sauerstoffes verbrauchen. Um den Zusatz an brennbaren Substanzen möglichst klein halten zu können, ist vorgeschlagen worden, geringe Mengen von Katalysatoren, wie Metalloxyde oder Kobalt, dem Pulvergemisch beizugeben bzw. dem Gemisch eine geringe Menge eines Stoffes zuzufügen, welcher sich beim Erhitzen unter Gasentwicklung bereits zersetzt, noch ehe die Schmelztemperatur des Sauerstoffträgers erreicht ist. Es wurde gefunden, daß sich die Zersetzungsgeschwindigkeit eines sauerstoffabspaltenden Gemisches bedeutend steigern läßt, wenn an Stelle der bisher verwandten Metalle oder Legierungen solche Metalle beigemischt werden, welche durch Zersetzung von Metallcarbonylen gewonnen wurden, z- B. Carbonvleisen. Auch der teilweise Ersatz der Metalle durch Carbonyleisen hat eine Beschleunigung der Zersetzung zur Folge; beispielsweise wurde die Zersetzungsgeschwindigkeit einer sauerstoffabspaltenden Mischung, welche ro°(Q fein gemahlenes Eisenpulver als brennbaren Bestandteil enthielt, um das Doppelte erhöht, wenn das Eisenpulver mit gleichen Teilen Carbonyleisenpulver gemischt wurde. Es genügt daher, eine geringere Zugabe brennbarer Stoffe, um eine völlige Zersetzung des an einer Stelle örtlich erhitzten Pulvergemisches zu gewährleisten, wodurch die Ausbeute an Sauerstoff erhöht wird.The organic bodies that sustain combustion are carbon, substances containing hydrocarbons and resins, as inorganic body agents such as iron or copper, as well as silicon and metals in the form of alloys been. The addition of flammable components, which are necessary to reach the decomposition temperature the oxygen-releasing agent is necessary, has the disadvantage that the Yield of oxygen is reduced, as the burning substances cause their combustion consume some of the oxygen. To the addition of flammable substances To be able to keep as small as possible, it has been proposed to use small amounts of catalysts, such as metal oxides or cobalt, to be added to the powder mixture or to the mixture to add a small amount of a substance which, when heated, evolves gas already decomposed before the oxygen carrier has reached its melting temperature is. It has been found that the rate of decomposition of an oxygen-releasing Mixture can be increased significantly if instead of the previously used metals or alloys such metals are added, which by decomposition of Metal carbonyls were obtained, e.g. carbon fiber. Also the partial replacement of metals by carbonyl iron accelerates the decomposition; for example, the rate of decomposition was an oxygen-releasing one Mixture containing ro ° (Q finely ground iron powder as a combustible component, increased by twice if the iron powder with equal parts carbonyl iron powder was mixed. It is therefore sufficient to add a smaller amount of flammable substances to one to ensure complete decomposition of the powder mixture, which is locally heated at one point, whereby the yield of oxygen is increased.
