FIELD: chemistry.
SUBSTANCE: method includes hydropurification of hydrocarbon flow in presence of hydrogen flow for hydropurification and hydropurification catalyst to obtain output hydropurification flow; separation of said output hydropurification flow into vapour output hydropurification flow, containing hydrogen, and liquid output hydropurification flow; fractioning said liquid output hydropurification flow to obtain flow of naphtha and light fractions and flow of Diesel fuel; hydrocracking of second hydrocarbon flow, which contains said flow of Diesel fuel, in presence of hydrogen flow for hydrocracking and hydrocracking catalyst to obtain output hydrocracking flow; separation of output hydrocracking flow into vapour output hydrocracking flow, which contains hydrogen, and liquid output hydrocracking flow; and mixing said vapour output hydrocracking flow with said output hydropurification flow.
EFFECT: method makes it possible to obtain Diesel fuel with ultralow content of sulphur.
