Abstract
The present invention concerns doped catalysts on a mixed zeolite/alumino-silicate support with a low macropore content, and hydrocracking/hydroconversion and hydrotreatment processes employing them. The catalyst comprises at least one hydrodehydrogenating element selected from the group formed by elements from group VIB and group VIII of the periodic table and a doping element in a controlled quantity selected from phosphorus, boron and silicon, and a support based on zeolite Y defined by a lattice parameter a of the unit cell in the range 24.40×10−10 m to 24.15×10−10 m and silica-alumina containing a quantity of more than 5% by weight and 95% by weight or less of silica (SiO2).
