Abstract
The inventive solvent extraction process uses hydrotreated (HTR) and low sulfur (LSR) resids feedstreams in a single deasphalter unit and in a way that optimizes the disposition of the oils, resins, and asphaltene fractions of each resid for downstream processing. After the refractory asphaltenes are separated from the HTR feedstream, the LSR resid is introduced into the deasphalter so that its resin and asphaltene fractions are combined with the HTR resins. The oils fractions from the two resids are combined and then used as a feedstock for catalytic cracking.
