A moderate pressure hydrocracking process is disclosed in which substantially dealkylated heavy distillate feedstocks are processed directly to high octane gasoline over a catalyst, preferably comprising a crystalline silicate zeolite hydrocracking component having a Constraint Index less than 2. The bottoms fraction produced from the contacting may be passed to an FCC unit for further processing. In another embodiment, the substantially dealkylated heavy distillate feedstock may be fractionated into a lighter boiling stream and a heavier boiling stream for better ease of processing. |
