1. A process for the conversion of hydrocarbon comprising:

  • introducing a hydrocarbon feedstock into an atmospheric distillation unit to form products including straight run light distillate, straight run mid-distillate and atmospheric bottoms;

    introducing the atmospheric bottoms into a vacuum distillation unit to form products including straight run vacuum gas oil and vacuum residue;

    introducing the vacuum residue into a liquid phase or slurry phase first stage hydroconversion reactor in a slurry phase hydrocracking unit to form first stage reaction products;

    introducing the first stage reaction products and the straight run vacuum gas oil into a second stage hydroprocessing reaction section in the slurry phase hydrocracking unit to thin second stage reaction products;

    introducing the second stage reaction products into a fractionation unit to form recovered products including fuel gas, recovered naphtha, recovered mid-distillates and recovered unconverted vacuum gas oil; and

    introducing at least a portion of the recovered unconverted vacuum gas oil as a recycle stream into the second stage hydroprocessing reaction section in the slurry phase hydrocracking unit, wherein the atmospheric distillation unit and the vacuum distillation unit produces no products that are introduced into a fluid catalytic cracking (FCC) unit.
