FIELD: oil refining.
SUBSTANCE: thermal process for producing a sintering additive to the charge for coking coal from heavy oil residues. The method includes visbreaking of tar to obtain visbreaking residue, which is subjected to fractionation in a distillation column, vacuum distillation of visbreaking residue from the distillation column to obtain vacuum visbreaking residue. Moreover, before vacuum distillation, visbreaking residue is heated to a temperature of 350-400°C and mixed with pyrolysis tar in the amount of 5-25 wt.% for the mixture.
EFFECT: improved quality of the sintering additive.
