Description

Verfahren zur katalytischen Herstellung von Wasserstoff und Phosphorsäure. Die Herstellung von Wasserstoff und Phosphorsäure durch Einwirkung von Wasserdampf mit oder ohne Anwesenheit von Sauerstoff oder sauerstoffhaltigen Gasen auf Phosphordampf verläuft auch bei Gegenwart der für diese Reaktion vorgeschlagenen Kontaktkörper Tonscherben, Bauxit und Eisenoxyd nicht zufriedenstellend, wenn nicht eine unerwünscht geringe Strömungsgeschwindigkeit oder großer Wasserdampfüberschuß oder beides angewendet wird. Außerdem hat das genannte Verfahren den Nachteil, daß die erforderliche Reaktionstemperatur sehr hoch ist, wodurch u. a. in beträchtlichem Maße die niederen Oxydationsstufen des Phosphors auftreten.Process for the catalytic production of hydrogen and phosphoric acid. The production of hydrogen and phosphoric acid through the action of water vapor with or without the presence of oxygen or gases containing oxygen on phosphorus vapor proceeds even in the presence of the contact bodies proposed for this reaction Pottery shards, bauxite and iron oxide unsatisfactory, if not an undesirable one low flow rate or large excess of water vapor or both are used will. In addition, the process mentioned has the disadvantage that the required reaction temperature is very high, whereby inter alia the lower degrees of oxidation to a considerable extent of phosphorus occur.

Es hat sich nun gezeigt, daß man schon bei verhältnismäßig niederen Temperaturen rasch und mit vorzüglichen Ausbeuten an Phosphorsäure arbeiten kann, wenn man als Katalvsatoren Kohle in den verschiedensten Formen verwendet. Man erhält so schon bei verhältnismäßig niedrigen Temperaturen, beispielsweise bei 6oo° und darunter, vorzügliche Ausbeuten an Phosphorsäure. Als geeignete Kohlen haben sich z. B. Halbkoks aus Steinkohle oder Braunkohle (Grude) und nach den verschiedensten Verfahren aktivierte natürliche oder künstliche Kohlen erwiesen. Die Einwirkung des Wasserdampfes auf die Kohle ist bei den in Betracht kommenden niedrigen Reaktionstemperaturen in der Regel sehr gering. Neben Wasserdampf kann man auch noch kleinere oder größere Mengen Sauerstoff oder Tuff auf den Phosphordampf einwirken lassen, wobei man im letzteren Falle zti einem Wasserstoff-Stickstoff-Gemisch gelangt, das z. B. für die Ammoniaksynthese Verwendung finden kann. Die gebildete Phosphorsäure bzw. ihr Anhy drill destilliert ab.It has now been shown that one can already do with relatively low Temperatures can work quickly and with excellent yields of phosphoric acid, when coal is used as a catalyst in the most varied of forms. You get so even at relatively low temperatures, for example at 600 ° and including excellent yields of phosphoric acid. Appropriate coals have proven to be z. B. semi-coke from hard coal or lignite (Grude) and according to the most varied Proven activated natural or artificial coals. The impact of the water vapor on the coal is at the low reaction temperatures in question usually very low. In addition to water vapor, you can also use smaller or larger ones Allow quantities of oxygen or tuff to act on the phosphorus vapor the latter case zti a hydrogen-nitrogen mixture which z. B. for the ammonia synthesis can be used. The phosphoric acid formed or you Anhy drill distills off.
