wandlungsreaktionen Die erfindung betrifft Katalysatoren mit einer speziellen geometrischen Form, die fuer die hydrierende Umwandlung, insbesondere Hydroraffination, hochsiedender Kohienwasserstofffraktionen geeignet sind.Conversion reactions The invention relates to catalysts with a special geometric shape necessary for the hydrogenative transformation, in particular Hydro refining, high-boiling hydrocarbon fractions are suitable.
Bekannt sind Hydroraffinationskatalysatoren, die zur Verbesserung des Wirkungsgrades in speziellen Formen hergestellt werden. In der US-PS 3674680 werden die Kleeblattform, die Kreuzform, die Ringform und eine C-Form beschrieben.Hydro refining catalysts are known which improve the efficiency can be produced in special forms. U.S. Patent 3,674,680 the clover-leaf shape, the cross shape, the ring shape and a C-shape are described.
Des weiteren werden Katalysatorformen gemaess DE-OS 2354558 beansprucht, die eine mehrlappige Querschnittsform aufweisen, wobei die mappen durch Kombination oder Verschmelzung von Kreisen gebildet werden, zum Beispiel eine Hantel, eine Achterfigur und ein dreiblaettriger lee ("Trilobes"). In einer anderen Patentschrift DE-OS 2817839 werden solche Kleeblattformen such als Dreifach- oder Vielfachkeulchen bezeichnet 9 wobei es aber keinen prinzipiellen Unteschield zu den in der vorhergehenden Po beschriebenen charakteristischen Form gibt, Katalysatoren in Form laenglicher Extrudate, die im Querschnitt Vorspruenge und Einkerbungen zeigen, werden auch in der US-PS 41 33777 genannt0 Die DE-OS 28337018 beschreibt einen Katalysator mit sternfoe:r migem Querschnitt, vorzugsweise in Form eines Dreizackaterns.Furthermore, catalyst forms according to DE-OS 2354558 are claimed, which have a multi-lobed cross-sectional shape, the folders by combination or merging of circles, for example a dumbbell, a figure of eight and a three-leaf lee ("Trilobes"). In another patent DE-OS 2817839 such shamrocks are such as triple or multiple clubs designated 9 although there is no fundamental Unteschield to those in the previous Po described characteristic shape, catalysts in the form of elongated extrudates, which show protrusions and indentations in cross-section are also used in US Pat 41 33777 mentioned0 The DE-OS 28337018 describes a catalyst with sternfoe: r moderate cross-section, preferably in the form of a three-pointed lizard.
iese Form soll gegenuber den anderen Formen an der Katalysatoroberflaeche keine Fluessigkeitsmenisken bilden9 in denen nur ein verminderter Stoff- und Energieransport stattfinden wurden Trotz dieser schron beschriebenen Formenvielfalt besitzen die bekannten Watalysatoren noch die Nachteile, dass sie entweder - eine unguenstige hydrodynamische Form besitzen und/ober - mechanisch wenig stabil sind und/oder technisch schlecht herstellbar sind und/oder - ihre Aktivitaet und Standzeit noch nicht befriedigen.This shape should be compared to the other shapes on the catalyst surface no liquid menisci form9 in which only a reduced transport of matter and energy took place Despite the variety of forms described above, the known Watalysts still have the disadvantages that they either - an unfavorable one have a hydrodynamic shape and / or are mechanically unstable and / or technically are difficult to manufacture and / or - their activity and service life are not yet satisfactory.
Das Ziel der Erfindung besteht darin, formspezifische Katalysatorteilchen zu finden9 die auf Grund ihrer neuen Form mechanisch stabil sind, sich technisch leicht herstellen lassen und beirn Einsatz hohe Aktivitaet und Standzeit aufweisen.The aim of the invention is to provide shape-specific catalyst particles to find9 which are mechanically stable due to their new shape, technically Can be easily manufactured and have a high level of activity and service life when in use.
Der Erfindung liegt die Aufgabe zugrunde, formspezifische Katalysatorteilchen fuer Kohlenwasserstoffumwandlungreaktionen zu entwickeln, die durch eine neue geometrische Form zur Verarbeitung hochsiedender Kohlenwasserstoffreaktionen besonders geeignet sind, Diese Aufgabe wird geloest, indem erfindungsgemaess der Katalysator aus extrudierten Teilchen besteht, deren Querschnitte aus Figuren gebildet werden9 die als aeussere Begrenzung weitgeschwungene Boegen aufweisen, welche durch kurze Boegen entgegengesetzter Kruemmung miteinander verbunden sind, wobei gerade Verbindungslinien zwischen Punkten auf den weiten Boegen ausserhalb des geometrischen Koerpers verlaufen und dass der Katalkysator ein Forenvolumen von 0,40 bis 0,90 cm³/g, einen mitteleren Porendurchmesser von 4 bis 20 mm, eine spezififische Oberflaeche von 150 bis 300 m²/g, ein Verhaeltnis von geometrischer Cberflaeche zu geometrischen Volumen von 100 bis 600. cm , einen Anteil von Poren mit murchmessern von 25 bis 3750 nm von weniger als 5 % des Gesamtporenvolumens und einen Anteil von Poren mit Durchmessern von 3 bis 10 nm von mindestens 90 % des Gesamtvolumens besitzt.The invention is based on the object of form-specific catalyst particles for hydrocarbon conversion reactions to develop, which by a new geometrical Form particularly suitable for processing high-boiling hydrocarbon reactions This object is achieved by according to the invention the catalyst from extruded Particles whose cross-sections are formed from figures9 as outer Boundaries have wide arched arcs, which are opposed by short arcs Curvature connected with each other, with straight connecting lines between points on the expanses Arches run outside the geometric body and that the catalytic converter has a fora volume of 0.40 to 0.90 cm³ / g, a medium one Pore diameter from 4 to 20 mm, a specific surface area from 150 to 300 m² / g, a ratio of geometric surface to geometric volume of 100 to 600 cm, a proportion of pores with diameters from 25 to 3750 nm of less than 5% of the total pore volume and a proportion of pores with diameters from 3 to 10 nm of at least 90% of the total volume.
Das Gebilde (Wirbelform) hat vorzugsweise drei Arme. Es koennen aber auch zwei, vier oder mehr Arme gewaehlt werden.The structure (vortex shape) preferably has three arms. But it can also two, four or more arms can be chosen.
Der Katalysator besitzt vorteilhafterweise ein Porenvolumen von 0,60 bis 3,90 cm3/g.The catalyst advantageously has a pore volume of 0.60 up to 3.90 cm3 / g.
Es ist guenstig, wenn der Katalysator einen mittleren Porendurchmesser von 9 bis 20 nm aufweist.It is advantageous if the catalyst has a medium pore diameter from 9 to 20 nm.
Vorteilhafterweise besitzt der Katalysator eine spezifische Oberflaeche von 150 bis 250 m²/g.The catalyst advantageously has a specific surface area from 150 to 250 m² / g.
Beispiele fuer den Querschnitt des erfindungsgemaessen Gebildes bieten die beiliegenden Abbildungen.

However, it is possible that the catalyst particles due to different radii of curvature and different lengths of the arms an irregular one Have shape, whereby the pelvic volume is to be controlled.
Ausserdem koennen auch Boegen mit ungleichmaessiger Kruemmung verwendet werden.In addition, arches with uneven curvature can also be used will.
Der Fachmann wuerde einer solchen Katalysatorform normalerweise eine ungenuegende mechanische Festigkeit zuschreiben.The person skilled in the art would normally use one such form of catalyst ascribe insufficient mechanical strength.
entgegen dieser Erwartung kann man aber Katalysatorteilchen herstellen, die auch im Vergleich mit dem bisher bekannten Kat alysatorformen ausgezeichnete Bruch- und Abriebfestigkeiten besitzen, Der vorgeschlagene formspezifische Katalysator, der aufgrund der Literaturangaben weniger vorteilhaft als beispielsweise ein Kleeblattprofil sein muesste, uebertrifft ueberraschenderweise andere bekannte Formen in seiner Wirksamkeit deutlich.contrary to this expectation one can produce catalyst particles, which is also excellent in comparison with the previously known Kat alysatorformen Have breaking and abrasion resistance, the proposed shape-specific catalyst, which, based on the literature, is less advantageous than, for example, a clover leaf profile Surprisingly, it surpasses other known forms in its Effectiveness clearly.
