Abstract
In the hydrocracking of hydrocarbon feedstocks in the presence of a hydrogenation catalyst on a cracking catalyst base in which the feed is pretreated by catalytic hydrofining to reduce the nitrogen content fresh hydrogen is introduced only into the hydrocracking stage and excess gas from that stage is recycled in part to each stage while excess hydrogen from the hydrofining stage is partly bled off and partly recycled to the hydrofining and none of the recycled gases is subjected to purification. Feed boiling in the range 204-566 DEG C. is hydrofined to a nitrogen content below 25 p.p.m. at 288-399 DEG C., 14-140 kg/cm.2 g. and 0.5-10 vol/vol/hr. in the presence of 17.8-356 S.C.M. of hydrogen per 100 litres of feed and oxides and/or sulphides of Group VIa or iron-group metals on an inactive support. The effluent may be fractionated with the hydrocracked product in which product gasoline is recovered and the bottoms are hydrocracked at 232-427 DEG C., 35-140 kg/cm.2 g. and 0.1-10 vol/vol/hr. in the presence of 35.6-356 SCM/100 litres of hydrogen and a Group VIa or VIII metal or oxide or sulphide thereof on a cracking support.
