摘要
The present invention relates to a process for producing middle distillates by hydrocracking a heavy distillate oil under middle pressure in which a hydrofining catalyst and a hydrocracking catalyst are used in series and once-through operation. The once-through volume conversion to 350 °C products is up to 80 vol.%. The yield and selectivity of middle distillates are greater than 40 wt.% and less than 50 wt.%, respectively. The process is particularly suited to treat heavy distillate oil having the nitrogen content of up to 1500 ppmw, the sulfur content of up to 3.5 wt.% and dry point of the boiling range of higher than 500 °C to produce the feed for reforming process jet fuel, the low sulfur content diesel, the feed for catalytic cracker and the feed for producing ethylene.
