The porosity of oxides of the metals manganese, cobalt, cup rate of the sintered stones is advantageously around 35 to fer, silver and lead are 40% by volume with the decomposition. In addition to the existing pores of hydrogen peroxide, the requirements mentioned can be met in a satisfactory manner by the preferably plate-shaped sintered stones. The catalyst used, advantageously with a boil lysator running parallel to one another, is insensitive to the stabilizers contained in the water, which completely contain peroxide of the sinter stone, and it has to penetrate. As a result, the drainage of the water has a long service life, which is due in particular to the decomposition reaction and the fact that it facilitates the escape of oxygen in its effectiveness. The bonding stabilizers are not adversely affected. In addition, the diameter of the catalyst in hydrogen peroxide 15 is about 1 mm, for example, and is insoluble on every square centimeter. Finally, the largest side surface of the sintered stone in each case also makes itself very advantageous. It can be noted that the catalyst already has about 40 to 50 bores, for example. So temperature is very active, so that already at the beginning, for example, sintered stones with the dimensions of the decomposition reacticin their full effectiveness to solutions 50 mm X 70 mm X 15 mm and a gelation. This is for example used with a large weight of about 35 g. The holes are important when the catalvtic decomposition of stretching themselves between the two sides-hydrogen peroxide for the production of oxygen for areas with the dimensions 50 mm X 70 mm.
Fuel elements is used because then after soaking with the warm, concentrating immediately when the fuel elements th solution of the metal nitrates are put into operation, the carrier can be supplied with the required 35 to achieve full power at a temperature of about 80 to 90 ° in the dry oxygen quantity . cupboard dried.

Die vorteilhaften Wirkungen des Mischoxidkatalysators dürften auf der Kombination der Metalloxide beruhen. Untersuchungen haben nämlich gezeigt, daß mit den einzelnen Metalloxiden diese Wirkungen nicht erreicht werden kennen. So wird beispielsweise Silber ziemlich schnell inaktiviert und Kupfer weist bei Raumtemperatur keine ausreichende Aktivität auf; MnO2 wird ziemlich schnell vom Trägermaterial abgelöst. Die hohe Aktivität des Mischoxidkatalysators bei Raumtemperatur dürfte auf den Gehalt an Bleioxid zurückzuführen sein.The advantageous effects of the mixed oxide catalyst are likely to be based on the combination of the metal oxides. Investigations have shown that these effects cannot be achieved with the individual metal oxides. For example, silver is inactivated fairly quickly and copper does not have sufficient activity at room temperature; MnO 2 is detached from the carrier material fairly quickly. The high activity of the mixed oxide catalyst at room temperature can be attributed to the lead oxide content.
