Abstract
The method includes a first stage of visbreaking of heavy oil residues and a second stage of thermal cracking of heavy catalytic gas oil formed in the visbreaking process. Thermal residue and lighter products are formed after the thermal cracking, and: (a) the thermal residue formed in the thermal cracking stage is practically used entirely, and (b) the fresh residue compositions of heavy oil, diluted with the thermal residue produced in stage (a) is fed a second time to the visbreaking stage.
