FIELD: oil industry.
SUBSTANCE: method comprises treating heavy oil with a hydrogen-containing gas whose temperature exceeds 649°C for less than 10 s, cooling the treated oil by means of mixing it with the untreated heavy oil, and stabilizing the treated oil for 1-60 min. The device comprises reaction chamber, means for supplying heavy oil, fuel, and oxidizing agent to the first end of the reaction chamber as separated flows, and means for igniting fuel and oxidizing agent to initiate the reaction for enriching the heavy oil in the reaction chamber.
EFFECT: improved quality of light oil and reduced cost.
