FIELD: technological processes.

SUBSTANCE: invention relates to a method for producing light oil by liquefying biomass. Method of production of light oil is carried out by liquefying biomass, while it includes the following stages: (1) mixing biomass, hydrogenation catalyst, and selective refining oil to prepare a biomass slurry; (2) performing first liquefaction reaction with a suspension of biomass and gaseous hydrogen to obtain the first reaction product; (3) performing a second liquefaction reaction with the first reaction product and hydrogen gas to obtain a second reaction product; (4) subjecting the second reaction product to the first separation operation to obtain a light component and a heavy component; (5) performing vacuum distillation of the heavy component to obtain a light fraction; (6) mixing the light component with a light fraction to form a mixture, performing a mixture hydrogenation reaction to obtain a hydrogenation product; and (7) subjecting the hydrogenation product to fractionation operations to produce a light oil.

EFFECT: increased light oil yield.
