FIELD: petroleum processing.
SUBSTANCE: petroleum is rectified to produce mazut, which is subjected to vacuum distillation to give vacuum distillate with boiling range 330 to 520оС and goudron. Vacuum distillate is then subjected to catalytic cracking producing fraction 150-400оС and goudron is subjected to delayed coking to give fraction 150-400оС. These fractions are subjected to joint hydrogenation at volumetric flow rate 0.2-1.5 h-1. Hydrogenate is processed to isolate fraction 30-200оС, which is used as gasoline component or for other technological needs, and fraction 130-350оС, which is used as diesel fuel.
EFFECT: increased degree of purification of diesel distillates from sulfur with simultaneously obtained high-octane gasoline fraction.
