1. A process for converting heavy hydrocarbon feed into lighter hydrocarbon products comprising:

  • hydrocracking said heavy hydrocarbon feed slurried with a particulate solid material in the presence of hydrogen in a hydrocracking reactor to produce a hydrocracked stream including vacuum gas oil (VGO) and pitch;

    separating at least a portion of said hydrocracked stream in a first vacuum column to provide a first pitch stream and a first VGO stream; and

    separating at least a portion of said first pitch stream in a second vacuum column to provide a second pitch stream and a second VGO stream; and

    recycling the second VGO stream to the hydrocracking step.
