Description
Gewinnung von Phosphorsäure und hochwertigen Generatorgasen durch Behandeln von Phosphoriten mit Silikaten und Kohle In der Patentschrift 449 585 ist ein Verfahren beschrieben, wonach es möglich ist, Generatorgase, die aus einem Schachtofenprozeß stammen, in dem Rohphosphate mit Kohle und Silikaten verschmolzen werden, so zu behandeln, daß der in diesen Gasen in sehr verdünnter Form vorhandene Phosphor oxydiert wird, wobei die Generatorgase erhalten bleiben und nicht mitoxydiert werden.Production of phosphoric acid and high quality generator gases through Treating Phosphorites with Silicates and Charcoal In patent specification 449 585 describes a method according to which it is possible to generate generator gases from a Shaft furnace process originate in the rock phosphates fused with coal and silicates are to be treated in such a way that the present in these gases in a very dilute form Phosphorus is oxidized, with the generator gases being retained and not being oxidized will.
Dies geschieht bei Temperaturen von iooo bis 1300 ° C dadurch, daß in die Gase, die aus dem Schachtofen abziehen, so viel Luft eingeblasen wird, als zur Oxydation des Phosphors notwendig ist. Hierbei oxydiert zum Teil das Kohlenmonoxyd sich zu Dioxyd, wird aber bei der vorgeschriebenen Temperatur momentan wieder in Monoxyd zurückgebildet auf Kosten der Oxydation des restlichen Phosphors.This happens at temperatures of 100 to 1300 ° C in that as much air is blown into the gases drawn off from the shaft furnace as is necessary for the oxidation of phosphorus. This partially oxidizes the carbon monoxide turns into dioxide, but will momentarily revert to at the prescribed temperature Monoxide is regressed at the expense of the oxidation of the remaining phosphorus.
Dieser erste Prozeß, d. h. die Oxydation des Phosphors, läßt sich nun auch dadurch erreichen, daßlman'wanstatt Luft nur Kohlendioxyd den Phosphor enthaltenden Generatorgasen zuführt Auch in diesem Sonderfall wird der Phosphor bei der angegebenen Temperatur oxydiert und das Dioxyd von C auf CO reduziert.This first process, i. H. the oxidation of phosphorus can be We can now also achieve phosphorus by using only carbon dioxide instead of air containing generator gases also in this special case, the phosphor is oxidized at the specified temperature and the dioxide is reduced from C to CO.
Dies kann in gewissen Fällen von wirtschaftlichem Vorteil sein.In certain cases this can be of economic advantage.
