Description
Wie im Fall der meisten katalytischen Anwendungen der Zeolithe ist es vorteilhaft, daß mindestens ein Teil des urspünglich vorhandenen Alkalimetals durch Basenaustausch entfernt wird. Es wird bevorzugt, daß die Alkaliionen durch Wasserstoffionen oder durch Ionen, wie Ammoniumionen, ersetzt werden, welche durch thermische Behandlung zu Wasserstoffionen abgebaut werden können. Zahlreiche der vorstehend aufgeführten synthetischen Zeolithe werden häufig in einer Form erhalten, die einen bestimmten Anteil organischer Stickstoffkationen enthält, und in einem derartigen Fall wird das Verhältnis der durch Wasserstoff besetzten kationischen Stellen durch thermische Behandlung infolge des Abbaus der organischen Stickstof fka tion en zu Wasserstoffionen erhöht Die Kombination von Austausch und thermischer Behandlung ergibt deshalb diese Zeoiithe praktisch vollständig in der Wasserstofform, d. h. einem äußerst wirksamen katalytischen Zustand.
