METHOD OF HYDROPROCESSING GAS CUTTINGS USING A CATALYST BASED ON AMORPHOUS AMORPHOUS ALUMINA HAVING HIGH CONNECTIVITY

摘要

A process for the hydrotreatment of at least one gas oil fraction having a weighted average temperature (TMP) of between 240 ° C and 350 ° C using a catalyst comprising at least one Group VIB metal and / or at least one metal of the same is described. group VIII of the Periodic Table and a support comprising an amorphous mesoporous alumina having a connectivity (Z) greater than 2.7, said hydrotreatment process operating at a temperature between 250 ° C and 400 ° C, at a total pressure of between 2 MPa and 10 MPa with a ratio of volume of hydrogen per volume of hydrocarbon feedstock of between 100 and 800 liters per liter and at a Time Volumetric Speed (VVH) defined by the ratio of the volume flow rate of the liquid hydrocarbon feedstock by the volume of catalyst loaded into the reactor between 1 and 10 h -1.
