FIELD: chemistry.
SUBSTANCE: method comprises the following stages: hydrotreating the hydrocarbon flow in the presence of a hydrogen flow for hydrotreating and a hydrotreating catalyst; separating the hydrotreating output flow into the hydrotreating vapour hydrogen-containing output flow and the hydrotreating liquid output flow; fractionating the hydrotreating liquid output flow to produce a diesel fuel flow; and hydrocracking said diesel fuel flow in the presence of a hydrogen flow for hydrocracking and a hydrocracking catalyst to obtain a hydrocracking output flow; separating the hydrocracking output flow into the hydrocracking vapour outlet hydrogen-containing flow and the hydrocracked liquid output flow; and mixing said vapour output.
EFFECT: invention allows to obtain diesel fuel with ultra-low sulfur content.
