FIELD: chemistry.
SUBSTANCE: method of obtaining bitumen from acid sludge with use of a modifying additive is proposed. Technical carbon is the proposed modifying additive. The method of obtaining bitumen from acid sludge involves heating, neutralisation and oxidation, using an electrochemical method. The modifying additive is added in quantity of 1-3% mass for 100% mass of the oxidised raw material.
EFFECT: improved operation characteristics of the obtained bitumen.
