Beschreibung
Zusammenfassung:	An integrated hydrocracking and solvent deasphalting process that provides for removal from the heavy oil recycle stream heavy polycyclic aromatic compounds formed in the hydrocracking step and recycling the resulting deasphalted paraffinic oil as a feed to the hydrocracker reactor of the process for further conversion. Cette invention concerne un procédé d'hydrocraquage et de désasphaltage au solvant intégré, qui permet d'éliminer les composés aromatiques polycycliques lourds contenus dans un flux de recyclage d'huile lourde qui se sont formés lors de l'étape d'hydrocraquage et le recyclage de l'huile paraffinique désasphaltée destinée à alimenter le réacteur de l'hydrocraqueur à des fins de conversion supplémentaire.
