FIELD: oil and gas industry.
SUBSTANCE: modernization method includes: contacting the hydrocarbon bottoms and hydrogen with a hydroconversion catalyst in a bottoms hydroconversion reactor system; extraction of effluent from the bottoms hydroconversion reactor system; separating the effluent from the bottoms hydroconversion reactor system to recover two or more hydrocarbon fractions comprising at least a fraction of the oil vacuum residue and a heavy vacuum gas oil fraction; combining at least a portion of the heavy vacuum gas oil fraction and at least an oil vacuum residue fraction to form a mixed heavy hydrocarbon fraction; feeding at least a portion of the mixed heavy hydrocarbon fraction to the coker unit; the coker unit functioning under the conditions of producing green anode coke and hydrocarbon distillate; extraction of the hydrocarbon distillate out of the coker unit; fractionation of the hydrocarbon distillate, extracted from the coker unit, to separate three or more hydrocarbon fractions including a light distillate fraction, heavy coker gas oil fraction and coker recycling fraction, where the coker unit is operated at a temperature of at least 500°C at the outlet of the heating coiler.
EFFECT: invention makes it possible to obtain anode coke.
