The problem of processing vacuum residues is relevant due to the enhancement of heavy crude oil recovery. The processing of fuel oil and vacuum residues is complicated due to the high content of resins and asphaltenes present in them. In order to develop new approaches to the processing of vacuum residues, it is necessary to comprehend the mechanisms of thermal degradation of high-molecular-weight oil components. Three samples of high-sulfur vacuum residues are cracked at a temperature of 500 °C and with a various process duration. The characteristic changes in the material and fractional composition of the products of the vacuum residue cracking depending on the process conditions are shown. It is found that the ratio of light to medium distillates in the composition of the products depends on the duration of cracking.
