The invention relates to a catalyst that contains at least one matrix, at least one zeolite and at least one hydro-dehydrogenating element that is located at the matrix (deposited on the catalyst or contained in the matrix), in which the zeolite contains in its porous network at least one element of group VIB and/or group VIII. Said hydro-dehydrogenating element preferably belongs to group VIB and/or to group VIII of the periodic table. The catalyst contains at least one promoter element)phosphorus, boron, silicon). The invention also relates to the use of this catalyst for the transformation of hydrocarbon fractions, in particular hydrorefining and hydrocracking

The invention relates to a catalyst that contains at least one matrix, at least one zeolite and at least one element that is deposited on the catalyst or contained in the matrix and selected from the group that is formed by the elements of groups VIB, VIII and VB, and at least one promoter element (phosphorus, boron, silicon), in which the zeolite contains in its porous network at least one element of group VB. The invention also relates to the use of this catalyst for the transformation of hydrocarbon fractions, in particular hydrorefining and hydrocracking.

For transforming hydrocarbons into aromatic compounds, the reaction is conducted on a homogeneous bed of catalyst particles, said catalyst comprising at least one amorphous matrix, at least one noble metal, at least two additional metals M1 and M2 and at least one halogen, and in which, for a catalyst particle, C is the local concentration of platinum; C is the local concentration of additional metal M1; C is the local concentration of additional metal M2; in which the standard deviation of the distribution of the local ratios of the concentrations of the additional metals, C /C , measured along the particle diameter, is better than 25% relative.
