Abstract:
(DE) Der Gegenstand der vorliegenden Erfindung ist ein Katalysator, der einen Träger und ein katalytisch aktives Material enthält. Die Partikel des katalytisch aktiven Materials sind dabei bimodal größenverteilt. Die Fraktion der größeren Partikel des katalytisch aktiven Materials und die Fraktion der kleineren Partikel des katalytisch aktiven Materials liegen gleichmäßig vermischt in der katalytisch aktiven Schicht des Katalysators vor. Das katalytisch aktive Material beträgt 50 Gew.-% oder weniger bezogen auf den Katalysator. Die Erfindung betrifft weiterhin ein Verfahren zur Herstellung oder zur Regenerierung eines erfindungsgemäßen Katalysators. Ein auf einem Träger befindliches katalytisch aktives Material wird dabei in einem ersten Schritt koaguliert. In einem weiteren Schritt wird ein weiteres katalytisch aktives Material auf den Träger aufgebracht. Die Erfindung betrifft weiterhin die Verwendung des katalytisch aktiven Materials zur Dehydrierung von fünf- oder sechsgliedrigen kohlenstoffhaltigen Molekülringen zu aromatischen Verbindungen.
(EN) The present invention relates to a catalyst, containing a carrier and a catalytically active material. The particles of the catalytically active material are distributed bimodally according to size. The fraction of larger particles of the catalytically active material and the fraction of smaller particles of the catalytically active material are evenly mixed in the catalytically active layer of the catalyst. The catalytically active materials amounts to 50 wt. % or less relative to the catalyst. The invention also relates to a method for producing or for regenerating a catalyst such as that claimed. In a first step of the method, a catalytically active material located on a carrier is coagulated. In a further step, an additional catalytically active material is applied to the carrier. The invention also relates to the use of the catalytically active material for the dehydrogenation of five or six-membered carbon-containing molecular rings to produce aromatic compounds.
(FR) L'invention concerne un catalyseur contenant un support, ainsi qu'une matière catalytiquement active dont les particules sont réparties dimensionnellement de manière bimodale. La fraction des particules plus grandes de la matière catalytiquement active et la fraction des particules plus petites de la matière catalytiquement active sont présentes de manière uniformément mélangée dans la couche catalytiquement active du catalyseur. La matière catalytiquement active représente au plus 50 % en poids par rapport au catalyseur. L'invention concerne également un procédé pour la production ou la régénération d'un catalyseur selon l'invention. Selon ce procédé, une matière catalytiquement active située sur un support est coagulée lors d'une première étape et une autre matière catalytiquement active est appliquée sur le support lors d'une étape suivante. L'invention concerne en outre l'utilisation de la matière catalytiquement active pour la déshydrogénation de cycles moléculaires carbonés à cinq ou six chaînons afin d'obtenir des composés aromatiques.
