The invention concerns a homogeneous catalytic particle bed, said catalyst comprising at least an amorphous matrix, at least a noble metal, at least an additional metal M and at least a halogen, and in which, for one catalyst particle: Cpt is the local concentration in noble metal; CM is the local concentration in additional metal M; Cx is the local concentration in halogen; catalyst particle bed, wherein the local dispersion of the value Cpt/CM or Cpt/Cx is said to be homogeneous along a particle diameter, which means that at least 70 % of the values Cpt/CM or Cpt/Cx varies at most by 30 % from the mean local ratio. The invention also concerns a method for transforming hydrocarbons into aromatic compounds with said catalyst such as a method for reforming petroleum products and the method for producing aromatics.
L'invention concerne un lit homogène de particules d'un catalyseur, ledit catalyseur comprenant au moins une matrice amorphe, au moins un métal noble, au moins un métal additionnel M et au moins un halogène, et dans lequel, pour une particule de catalyseur, C pt est la concentration locale en métal noble, C M est la concentration locale en métal additionnel M, C x est la concentration locale en halogène, lit de particules de catalyseur, dans lequel la dispersion locale de la valeur C pt/C M ou C pt/C x est dite homogène le long d'un diamètre de particule, ce qui conupond à ce que au moins 70 % des valeurs C pt/ C M ou C pt/C x s'écartent d'au plus 30 % du rapport moyen local. L'invention conceme également un procédé de transformation d'hydrocarbures en composés aromatiques avec ce catalyseur tel que le procédé de réformage des essences et le procédé de production d'aromatiques.
