Production of gasoline and distillate fuels from light cycle oil
This patent describes a process for the co-production of high quality gasoline and distillate products from catalytically cracked feedstocks. It comprises catalytically cracking a hydrocarbon feedstock to produce a substantially dealkylated cracked product, hydrocracking the substantially dealkylated product with a hydrocracking catalyst at a hydrogen partial pressure not greater than 1200 psig and a conversion to gasoline boiling range products not more than 75 wt. percent; separating the products of hydrocracking into a gasoline boiling range fraction, a first distillate range fraction boiling immediately above the gasoline fraction with an end point in the range of 450{degrees} to 500{degrees} F and a second, higher boiling distillate fraction which is more paraffinic than the first distillate fraction; recycling at least a portion of the first, lower boiling distillate fraction to the catalytic cracking step, recovering the second, higher boiling distillate fraction.
