Abstract
The present invention concerns doped catalysts on an alumino-silicate support with an adapted 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, a controlled quantity of phosphorus (optionally in combination with boron and/or silicon) as a doping element, and a non-zeolitic support based on alumina-silica containing a quantity of more than 5% by weight and 95% by weight or less of silica (SiO2).
