Abstract:
A catalyst in the form of balls or extrudates comprising at least one zeolite with structure type EUO, at least partially in its acid form, at least one matrix, and at least one metal from group VIII of the periodic table, the zeolite comprising silicon and at least one element T selected from the group consisting of aluminum, iron, gallium and boron, with a global Si/T atomic ratio over 5, the catalyst being characterized in that the dispersion of the group VIII metal is in the range 60% to 100%, limits included, and the macroscopic distribution coefficient of the group VIII metal is in the range 0.7 to 1.3, limits included, the catalyst having a mechanical strength such that the bed crush strength is more than 0.7 MPa said catalyst further comprising sulfur in an amount such that the ratio of the number of sulphur atoms to the number of atoms of deposited group VIII metal is in the range 0.5 to 2.
