Description

Verfahren zur Herstellung von Eisenkatalysatoren, die für den insbesondere unter hoher Gasbelastung durchgeführte katalytische Kohlenoxydhydrierung geeignet sind Zusatz zum Zusatzpatent 923 128 Das Patent 923 I28 beschreibt die Herstellung von Eisenkatalysatoren, die für die insbesondere unter hoher Gasbelastung durchgeführte katalytische Kohlenoxydhydrierung geeignet sind. Der geringe Mengen von Trägerstoffen und im üblichen Umfange Kupfer oder andere aktivierende Metalle enthaltende Katalysator wird hier in üblicher Weise gefällt und ein bestimmtes K20:SiO2-Verhältnis von etwla 1 :4 bis 1 :5 dadurch eingestellt, daß ein Teil der hierfür erforderlichen Gesamtkieselsäure statt mit Wasserglas nunmehr als andersgeartete Kieselsäure, z. B. aktivierende Bleicherde, eingeführt wird. Gleichzeitig wird das erforderliche Alkali direkt in Form von Wasserglas in den gewünschten Mengen zugesetzt. Die nach dem Hauptpatent erforderliche Behandlung mit Salpetersäure, die ohne Verwendung von aktivierter Bleicherde erforderlich war, konnte bei dieser Arbeitsweise entfallen. Process for the production of iron catalysts for the particular Catalytic hydrogenation of carbohydrates carried out under high gas loads is suitable are additions to additional patent 923 128 Patent 923,128 describes the manufacture of iron catalysts, which are carried out in particular under high gas loads catalytic carbon dioxide hydrogenation are suitable. The small amounts of carriers and catalyst containing conventionally copper or other activating metals is precipitated here in the usual way and a certain K20: SiO2 ratio of about 1: 4 to 1: 5 adjusted by the fact that part of the total silica required for this instead of water glass now as different types of silica, e.g. B. activating Fuller's earth, is introduced. At the same time, the required alkali is directly in In the form of water glass added in the desired amounts. The one according to the main patent required treatment with nitric acid without the use of activated Fuller's earth was required, could be omitted in this way of working.

Es konnte beobachtet werden, daß dieZusammensetzung der verwendeten Bleicherde oder der sonstigen kieselsäurehaltigen Massen einen nicht unerheblichen Einfluß auf das Verhalten des Katalysators während der Synthese besitzt. Auch die Zusammensetzung der erhaltenen - Primärprodukte war von dieser Zusammensetzung abhängig. It could be observed that the composition of the used Fuller's earth or the other silicic acid-containing masses a not insignificant Has an influence on the behavior of the catalyst during the synthesis. Also the composition of the primary products obtained was dependent on this composition.

Es wurde gefunden, daß besonders günstige Syntheseergehnisse mit diesen- Katalysatoren dann erzielt werden, wenn bei ihrer Herstellung solche Bleicherden verwendet werden, die einen möglichst geringen Aluminiumoxydgehalt von weniger als IO Gewichtsprozent, vorzugsweise weniger als 5 Gewichtsprozent, neben einem möglichst hohen CaO-Gehlalt von über 5 Gewichtsprozent, vorzugsweise über Io Gewichtsprozent, enthalten. It has been found that particularly favorable synthesis results with These catalysts are achieved when such bleaching earths are used in their production are used that have the lowest possible aluminum oxide content of less than IO weight percent, preferably less than 5 weight percent, next to one as possible high CaO content of over 5 percent by weight, preferably over 10 percent by weight, contain.

Ein hoher Aluminiumoxydgehalt bedingt bei den erfindungsgemäßen Katalysatoren eine vermehrte Methanbildung neben der Bildung von Produkten mit etwas tieferem Olefingehalt. -Umgekehrt ergibt ein entsprechend höherer Calciumoxydgehalt nicht nur eine verringerte Methanbildung, sondern einen erhöhten Anteil an ungesättigten ailipbatischen Kohlenwasserstoffen. The catalysts according to the invention have a high aluminum oxide content an increased methane formation in addition to the formation of products with something deeper Olefin content. Conversely, a correspondingly higher calcium oxide content does not result only a reduced methane formation, but an increased proportion of unsaturated aliphatic hydrocarbons.
