FIELD: oil and gas production.
SUBSTANCE: invention refers to procedure for processing black oil and heavy oil to distillate fractions by introduction activating additive to them on base of copper oxide with successive thermo-cracking. Also, as copper oxide there is used copper oxide of size 0.2+0.1 mm or copper oxide applied on γ-oxide of aluminium with contents of copper oxide 30 % wt, with size of particles 0.2+0.1 mm. Successively there is performed thermo-cracking at temperature 400-450°C. Activating additive is introduced at amount 10-15 % wt.
EFFECT: increased general output of distillate fractions of heavy oil and distillate fractions of black oil.
