摘要： The present invention relates to a process for the hydroconversion of heavy oil products which comprises the following steps in which heavy oil products and hydrogen are supplied to a slurry hydroconversion section which contains a molybdenum-based catalyst. The reaction effluent is separated into a vapour phase and a slurry phase. The slurry phase is sent to a separation section which has the function of separating the Vacuum Gas Oil (VGO), Heavy Vacuum Gas Oil (HVGO), Light Vacuum Gas Oil (LVGO), Atmospheric Gas Oil (AGO) fractions, from a stream of heavy organic products which contains asphaltenes, unconverted feed, catalyst and solid formed during the hydroconversion reaction. This stream is partly sent to the reaction section and partly forms a purge stream. The purge stream is heated and made fluid at temperatures comprised between 185°C and 220°C, and subsequently subjected to a static settling unit up to a minimum temperature of 100°C. From the settling unit two new products defined as clarified component and cake are obtained. The clarified component is recycled to the hydroconversion reaction section.
