Zusammenfassung:FIELD: petroleum processing. ^ SUBSTANCE: mazut is subjected to vacuum distillation to produce weighted goudron at residual column top pressure 30-50 mm Hg. Weighted goudron is mixed with organic feedstock additives, namely with petroleum processing products, at ratio between 80:20 and 98:2. Resulting is oxidized with air oxygen at 230-270°C to give product characterized by needle penetration depth 35-45.0.1 mm at 25°C. Oxidized product is finally compounded with mixture of weighted goudron and organic feedstock additive (prepared goudron) at ratio between 80:20 and 90:10 until needle penetration depth achieves 50-200.0.1 mm at 25°C. ^ EFFECT: improved performance characteristics of target product. ^ 1 tbl, 20 ex
