FIELD: oil industry.
SUBSTANCE: present invention relates to processing of heavy oil residues in order to obtain light oil products. Method consists in direct contact of oil residues with oxygen-containing gas in a cracking reactor at high temperature and pressure, includes removal of gaseous products from upper part of cracking reactor and heavy cracking products from lower part of reactor and extraction of light hydrocarbon fractions by rectification. Processing of heavy oil residues is performed in presence of unsaturated carboxylic acids and/or derivatives thereof.
EFFECT: method increases output of light fractions and specific efficiency.
