Patent ID: 7582204

Claim:
A process for the treatment of a hydrocarbon charge containing resin, at least 80% of the compounds of the charge having a boiling point which is above or equal to 340° C., said process comprising: a) fractionating the charge to recover: at least one heavy fraction comprising at least 90% by weight of compounds which boil at above 450° C. and at below 700° C., and at least one light fraction which boils at less than the heavy fraction(s), a residuum which boils at more than the heavy fraction(s), b) extracting at least part of the heavy fraction with a paraffinic solvent having 3 to 7 carbon atoms, to remove at least some of the resins contained in said heavy fraction and to recover a resin depleted fraction, c) in a stage separate from the extracting stage (5) and after removal of said paraffinic solvents from said resin-depleted heavy fraction, mixing directly at least part of the resin-depleted heavy fraction with at least one light fraction obtained in the fractionation stage, and d) passing the resultant mixture to a cracking stage.
