Production of gasoline and distillate fuels from light cycle oil
Patent
·
OSTI ID:5143627
This patent describes a process for the co-production of high quality gasoline and distillate products from catalytically cracked feedstocks. It comprises: hydrocracking a substantially dealkylated feedstock 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 distillate fraction boiling above the first distillate fraction; recycling at least a portion of the first distillate fraction to the hydrocracking step to effect saturation and partial cracking of aromatics in the recycled fraction to increase the paraffin content of the second distillate fraction; recovering the second distillate fraction.
