FIELD: petroleum industry.
SUBSTANCE: invention refers to oil refining, in particular, to petroleum cokemaking by method of delayed coking. Proposed is a petroleum cokemaking method that includes tar cocking at the first flow with making of common sulphur coke and heavy gas oil of delayed tar cocking. Then heavy gas oil of delayed cocking is subjected to mixture with heavy pyrolysis gum and heavy gas oil of catalytic cracking at % mass rate (60-65):(15-20):(15-20), obtained mixture being coked in the second flow to make the target low-sulfur coke.
EFFECT: obtaining low-sulfur coke from sulfur raw materials and secondary petroleum residuals by simplified method.
