Homogeneous bed of catalyst and a process for transforming hydrocarbons into aromatic compounds using said bed

摘要

The invention relates to a homogeneous bed of catalyst particles comprising at least one amorphous matrix, at least one noble metal, at least one additional metal M and at least one halogen, and in which, for a catalyst particle:CPt is the local concentration of noble metal;CM is the local concentration of additional metal M;Cx is the local concentration of halogen;in which catalyst particle bed the local dispersion of the value of CPt/CM or CPt/Cx is termed homogeneous along the diameter of the particle, which corresponds to at least 70% of the values CPt/CM or CPt/Cx deviating by a maximum of 30% from the local average ratio.The invention also relates to a process for transforming hydrocarbons into aromatic compounds with the catalyst, such as a gasoline reforming process and a process for producing aromatic compounds.
