Abstract: Method of hydroconversion of Heavy charges as feedstock comprising the steps of Hydrotreating a heavy charge in a slurry reactor in the presence of hydrogen and a dispersed hydrotreating catalyst deriving from said Molybdenum-based Precursor of catalyst to obtain an effluent (1) of hydroconversion reaction; Submitting the effluent (1) to gas-liquid separation to separate distillates in form of Vacuum Gas Oil (VGO), Heavy Vacuum Gas Oil (HVGO), Light Vacuum Gas Oil (LVGO), Atmospheric Gas Oil (AGO) fractions from at least one slurry phase comprising asphaltenes, unconverted feedstock, catalyst and solids formed during the hydroconversion reaction; characterized in that said method of hydroconversion further includes a primary solid-liquid separation to treat said at least one slurry phase separated from one or more distillates, said primary solid-liquid separation being selected from - cross flow filtration (CFF) without solvent, - diafiltration with a solvent, or - cross flow filtration (CFF) without solvent followed by a subsequent diafiltration with a solvent.
