The invention relates to a catalyst for the dehydrogenation of alkanes or alkyl substituents of hydro-carbons, containing a moulded body consisting of at least one or several oxides from an element of the second to fourth main group or subgroup of the periodic table or of a mixed oxide compound made up of the latter, the constituents serving as the basic material of the moulded body, an addi-tional component containing an oxide from an element of the fourth main group of the periodic ta-ble, the said oxide being added during the moulding process, and a platinum compound and a compound of an element of the fourth main group of the periodic table being selected as surface component of the catalyst. The invention also covers the production of the catalyst with the materi-als claimed by means of different process steps as well as a process for the dehydrogenation of al-kanes using the catalyst according to the invention.
Linvention concerne un catalyseur servant à la déshydrogénation des alcanes ou des substituants alkyl dhydrocarbures, comprenant un corps moulé qui est composé dau moins un ou de plusieurs oxydes déléments du deuxième au quatrième groupe principal ou auxiliaire de la classification périodique ou dun mélange doxydes produit à partir de ces derniers. Les constituants sont utilisés comme matériau de base du corps moulé ; on ajoute au cours du processus de formage un composant additionnel qui contient un oxyde dun élément du quatrième groupe principal de la classification périodique ; et on sélectionne un composé platine et un composé dun élément du quatrième groupe principal de la classification périodique en tant que composant de surface du catalyseur. Linvention concerne également la fabrication du catalyseur avec les matériaux revendiqués au moyen des différentes étapes du procédé, ainsi quun procédé de déshydrogénation dalcanes utilisant le catalyseur selon linvention.
