A catalyst including a matrix consisting of 0-100 wt.% of transition alumina ?, the balance to 100 wt.% of the matrix being transition alumina .gamma., and, based on the total weight of the catalyst, 0.001-2 wt.% of silicon, 0.1-15 wt.% of at least one halogen selected from the group which consists of fluorine, chlorine, bromine and iodine, 0.01-2 wt.% of at least one noble metal from the platinum family, 0.005-10 wt.% of at least one promoter metal selected from the group which consists of tin, germanium, indium, gallium, thallium, antimony, lead, rhenium, manganese, chromium, molybdenum and tungsten, and optionally 0.001-10 wt.% of a doping metal.

L'invention concerne un catalyseur comprenant: une matrice constituée de 0 à 100 % en poids d'alumine de transition , le complément à 100 % en poids de la matrice étant de l'alumine de transition .gamma., et par rapport au poids total du catalyseur; de 0,001 à 2 % en poids de silicium; de 0,1 à 15 % en poids d'au moins un halogène choisi dans le groupe formé par le fluor, le chlore, le brome et l'iode; de 0,01 à 2 % en poids d'au moins un métal noble de la famille du platine; de 0,005 à 10 % en poids d'au moins un métal promoteur choisi dans le groupe formé par l'étain, le germanium, l'indium, le gallium, le thallium, l'antimoine, le plomb, le rhénium, le manganèse, le chrome, le molybdène et le tungstène, et éventuellement de 0,001 à 10 % en poids d'un métal dopant.
