Abstract:
     The invention relates to a new hydrocarbon hydroconversion catalyst, which is a mixture of an amorphous matrix, a zeolite and at least one metal of Group VIII and if necessary of Group VI, the zeolite having a SiO2/Al2O3 molar ratio of about between 8 and 70, a sodium content of les than 0.15% by weight, a unit mesh parameter of between 24.55 and 24.24 x 10 to the power -10 m, a sodium ion recovery capacity CNa, expressed in grams of sodium per 100 grams of modified zeolite, greater than 0.85, a specific surface area greater than 400 sq.m/g, a water vapour adsorption catacity at 25 deg.C (with a P/Po ratio of 0.10) greater than 6% by weight, a pore distribution between 1 and 20% of the pore volume contained essentially in pores of diameters between 20 and 80 x 10 to the power -10 m, the remaining pore volume being contained essentially in pores of diameters less than 20 x 10 to the power -10 m.
