RESIDUE CONVERSION PROCESS THAT INCLUDES A DEASPHALTING STAGE AND A HYDROCONVERSION STAGE

摘要

Conversion of a heavy hydrocarbon fraction that is obtained either from a crude oil or from the distillation of a crude oil and that has an initial boiling point of at least 300° C. by hydroconversion of at least one portion of heavy hydrocarbon fraction in the presence of hydrogen in at least one three-phase reactor containing at least one hydroconversion catalyst, separation of the effluent to obtain a light liquid fraction that boils at a temperature that is less than 300° C. and a heavy liquid fraction that boils at a temperature that is greater than 300° C., and a deasphalting of at least one portion of the heavy liquid fraction that boils at a temperature that is greater than 300° C.
