ABSTRACT:
Process for reducing the viscosity of a highly viscous hydrocarbon charge containing 10-30% b.w. of constituents distilling above 375.degree. C., said treatment comprising hydrovisbreaking said charge to such an extent as to convert 10 to 30% of the 375.degree. C..sup.+ fraction to a 375.degree. C..sup.- fraction, fractionating the hydrovisbreaked product to separate a fraction comprising at least 90% of the constituents boiling below 375.degree. C. from a distillation residue, deasphalting said distillation residue and admixing at least a portion of the deasphalted distillation residue with at least a portion of said fraction comprising at least 90% of the constituents boiling below 375.degree. C.
