Resumen del autor, extraído del trabajo. Slurry processes offer an attractive option to deal with heavy feeds, because they combine the advantages of the C-rejection technologies in terms of flexibility with the high performances peculiar of the H-addition processes. The use of an active catalyst contributes to reduce the severity of the process and to improve the quality of the products. The process solution, here proposed, is based on the slurry hydrotreatment of the feedstock at a relatively low temperature in the presence of thousands ppm of a molybdenum-based dispersed catalyst, which is recycled via solvent deasphalting (overall technology performances: HDS>75%, HDM>99% and HDCCR>90%). Part of the feedstock is directly converted to distillates, while the Vacuum GasOil and the deasphalted oil may represent interesting feedstock for conventional catalytic cracking processes such as Fluid Catalytic Cracking or Hydrocracking. The process configuration is characterized by the possibility of performing the upgrading and the conversion of the residue in two separate and optimized stages. The main advantages of this process configuration are the following: feedstock flexibility (even the heaviest, highest metals content feedstocks can be upgraded), optimal hydrogen utilization/consumption, product slate flexibility (maximum gasoline from FCC or maximum high quality diesel oil from Hydrocracking), nearly complete conversion (> 95%) of the feedstock.
