ABSTRACT:
This invention provides a process for producing a distillate boiling-range hydrocarbon product which comprises hydrotreating a hydrodesulfurized aromatic, substantially dealkylated hydrocarbon feed produced by the catalytic cracking of a hydrocarbon fraction, the feed having an initial boiling point of at least 300.degree. F., an aromatic content of at least about 30 weight percent, a hydrogen content not more than about 12 weight percent and a sulfur content of not more than 5000 ppmw, in the presence of a catalyst comprising an inorganic, non-layered, porous, crystalline phase material having pores with diameters of at least about 13 .ANG. and exhibiting, after calcination, an X-ray diffraction pattern with at least one peak with a relative intensity of 100 at a d-spacing greater than about 18 .ANG., said material containing at least one Group VIII metal and less than 5000 ppm Na, said process being carried out at a hydrogen partial pressure of not more than 1000 psig to evolve product containing less than about 10 weight percent aromatics and less than 300 ppmw sulfur at a 390.degree. F.+ feed conversion of less than about 30 weight percent.
