ABSTRACT:
This invention provides an integrated process for converting a hydrocarbon feedstock having components boiling above 300.degree. F. into liquid fuel products boiling in the range of from about 80.degree. F. to about 700.degree. F., which process comprises passing said feedstock to a first stage hydrocracking zone to effect decomposition of organic sulfur and/or nitrogen compounds, passing a portion of the product from said first stage hydrocracking zone to a second stage hydrocracking zone, simultaneously passing the remaining portion of said product from said first stage hydrocracking zone to an aromatics saturation zone, and subsequently passing the product from said hydrocracking zone and said aromatics saturation zone to one or more fractionating zones wherein said products are separated into a tops fraction and a bottoms fraction, with the tops fraction being separated into light gasoline, naphtha, jet fuel and diesel fuel products, and a portion or all of the bottoms fraction being recycled to the hydrocracking zone and/or the aromatics saturation zone following the optional removal of heavies and polynuclear aromatics.
