FIELD: technological processes.

SUBSTANCE: invention relates to a method of producing bitumen and can be used in oil refining industry to obtain road bitumen. Described is a method of producing bitumen from a heavy oil-containing residue, characterized in that it includes preparation of raw material, during which components of raw materials are mixed, which are a mixture of heavy oil-containing residues in thermotropic mesophase, and liquid sulfur, the obtained mixture is heated to a sulfur polymerisation temperature and mixed in a medium without external oxidising agents, wherein to achieve homogeneity of the mixture during mixing, receipt and turbulent flows are formed throughout the volume of the material.

EFFECT: high quality of the obtained bitumen.
