FIELD: chemistry.
SUBSTANCE: process implies hydrotreatment of diesel fuel by catalytic treatment thereof in the presence of hydrogen-containing gas under elevated temperature and pressure resulting in hydrogenation product, separation of hydrogenation product resulting in hydrogen-containing gas and liquid phase, and stabilisation of liquid phase, distinguishing itself by the fact that 15-25% of liquid phase are recirculated to mix with diesel fuel feed to improve desulphuration.
EFFECT: improved desulphuration of diesesl fuel.
