FIELD: chemistry. ^ SUBSTANCE: invention relates to a method of obtaining diesel fuel, involving thermal treatment of raw material, separation of thermal treatment products into a light and a heavy fraction, hydrogenation refinement of the separated fractions. The light fraction of thermal treatment products undergoes hydrofining in a mixture with a straight-run diesel fraction and light gas oil from catalytic cracking, taken in weight ratio ranging from 20%-60%-20% to 40%-50%-10% respectively, and the remaining heavier fraction of thermal treatment products undergoes hydrocracking in a mixture a straight-run vacuum distillate in weight ratio ranging from 25%-75% to 75%-25% respectively. Diesel fractions boiling in the 160-370C temperature interval are extracted from hydrofining and hydrocracking products and then mixed in weight ratio ranging from 30%-70% to 60%-40%, respectively, to obtain the desired product. ^ EFFECT: high output of diesel fuel which meets modern requirements. ^ 4 cl, 3 ex |
