FIELD: chemistry.
SUBSTANCE: method of producing low-sulphur diesel fuel and high-octane naphtha is characterised by that the output stream of distillate from the hydrodesulphurisation reaction zone and the output stream from the hydrocracking reaction zone, supplied with dealkylated, high-aromatic material, are mixed and separated to obtain a gas stream of hydrogen, low-sulphur diesel fuel and high-octane naphtha.
EFFECT: feeding hydrogen as a source of hydrogen for the hydrodesulphurisation reaction zone minimises the load on the recirculation compressor, and use of a common separation and fractionation zone gives the advantage of lower capital and operational costs.
