A processing arrangement for upgrading crude oil by the combination of hydrodewaxing, and fluid catalytic cracking or hydrocracking to maximize the production of low pour, high quality distillate fuel oil is particularly described. Cracking of atmospheric bottoms of residua, hydrodewaxing atmospheric heavy gas oil and hydrodesulfurizing light gas oil material to produce diesel fuel oil products are primary components of the processing arrangement.

Production of high quality fuel oils

Enhanced compatibility of coal liquids with petroleum based fuels is achieved by removing or modifying the 950.degree. F. plus asphaltene-containing fraction of the coal liquid. The separation or modification can be achieved by distillation, deasphalting, hydroprocessing, and the like.

Compatible mixtures of coal liquids and petroleum based fuels

Hydroprocessing a high boiling hydrocarbon feed, such as coker gas oil, containing an aromatic carbon content of at least 35%, thereby reducing the aromatic carbon content level to less than 35% but not less than about 20%, prior to inclusion of this FCC feed component with the remainder of the FCC feed or cracking it alone with a crystalline zeolite aluminosilicate in a catalytic cracking zone.
