This patent describes a process for deasphalting a hydrotreated resid and substantially removing cracking catalyst fines from decanted oil containing cracking catalyst fines. It comprises mixing hydrotreated resid with a first non-aromatic C{sub 3}-C{sub 7} hydrocarbon solvent; treating the resid and solvent in a first separator, recovering a substantial amount of resin and asphaltene from the first separator; recovering a substantial amount of solvent and deasphalted solvent extracted oil from the first separator; feeding the solvent-oil mixture to a second separator; recovering solvent from the second separator; recovering substantially deasphalted solvent extracted oil from the second separator; and mixing the resin-asphaltene mixture with decanted oil containing cracking catalyst fines.
