Abstract
A process for the production of middle distillates comprising at least one hydrocracking stage that oligomerizes a paraffinic feedstock produced by Fischer-Tropsch synthesis, the process using a catalyst that comprises at least one hydrogenating-dehydrogenating metal that is selected from the group that is formed by the metals of group VIB and group VIII of the periodic table, by themselves or in a mixture, and a substrate that comprises a beta zeolite in the form of crystallites with a mean size that is less than 100 nm dispersed in at least one porous mineral matrix, whereby the beta zeolite has a mesopore volume of less than 0.4 ml/g.
