Description

Entfernung von Phosphor aus Gasgemischen Es ist bekannt, daß es außerordentlich schwierig ist, Phosphor bzw. Phosphorverbindungen aus Gasgemischen zu entfernen, besonders wenn die Gase nur wenig Phosphor enthalten. Es ist allerdings bekannt, bei bestimmten Temperaturen den Phosphor aus derartigen Gasgemischen mittels elektrischer Niederschlageinrichtungen zu entfernen, doch ist dies Verfahren nicht einfach genug.Removal of phosphorus from gas mixtures It is known to be extraordinary it is difficult to remove phosphorus or phosphorus compounds from gas mixtures, especially if the gases contain little phosphorus. However, it is known at certain temperatures the phosphorus from such gas mixtures by means of electrical To remove precipitation devices, but this procedure is not simple enough.

Es wurde nun gefunden, daß Kieselsäure-Gel imstande ist, aus darübergeleiteten phosphorhaltigen Gasgemischen, auch solchen mit geringem Phosphorgehalt, den Phosphor bzw. die Phosphorverbindungen zu adsorbieren. Den im Kieselsäure-Gel abgelagerten Phosphor kann man in bekannter Weise durch Auswaschen mit Schwefelkohlenstoff oder anderen bekannten Lösungsmitteln für Phosphor entfernen; man kann auch einen Luftstrom durch das mit Phosphor beladene Kieselsäure-Gel hindurchschicken, wobei man als Endprodukt nicht Phosphor, sondern die Oxyde bzw. Säuren des Phosphors erhält.It has now been found that silica gel is able to pass over it Phosphorus-containing gas mixtures, including those with a low phosphorus content, the phosphorus or to adsorb the phosphorus compounds. Those deposited in the silica gel Phosphorus can be obtained in a known manner by washing out with carbon disulfide or remove other known solvents for phosphorus; you can also use an air stream send through the phosphorus-laden silica gel, using as The end product does not contain phosphorus, but the oxides or acids of phosphorus.

Es hat sich bei Ausführung dieses Verfahrens weiter gezeigt, daß es vorteilhaft ist, dem Kieselsäure-Gel noch Zusätze von Metallen, Metalloxyden oder Metallsalzen zu geben, wie z. B. von Eisen, Nickel, Kobalt, Chrom, Mangan, Vanadium, Molybdän, Cer o. dgl.It has also been found in the execution of this method that it It is advantageous to add metals, metal oxides or additives to the silica gel To give metal salts, such as B. of iron, nickel, cobalt, chromium, manganese, vanadium, Molybdenum, cerium or the like

Das Kieselsäure-Gel läßt sich auch teilweise oder ganz durch Gele der Oxyde von Aluminium, Eisen, Zirkon, Zinn, Titan ersetzen, wobei man diesen Oxyden, z. B. dem kolloiden Aluminiumoxyd bzw. seinem Gemisch mit Kieselsäure-Gel auch die vorerwähnten Zusätze geben kann.The silica gel can also be partially or completely replaced by gels replace the oxides of aluminum, iron, zirconium, tin, titanium, whereby these oxides, z. B. the colloidal aluminum oxide or its mixture with silica gel also the can give the aforementioned additives.
