Abstract

Process for reducing the viscosity of heavy oil residues, which comprises a first step for the visbreaking of heavy oil residues and a second step for the thermal cracking (II) of the heavy gas oil formed in the visbreaking process, the above thermal cracking producing a thermal residue as well as lighter products, said process being characterized in that: (a) the thermal residue obtained in the thermal cracking step is almost totally recovered; (b) a composition consisting of fresh heavy oil residues diluted with the thermal residue recovered in step (a) is refed to the visbreaking step. <IMAGE>
