A process is disclosed for converting heavy hydrocarbon feed into lighter hydrocarbon products. The heavy hydrocarbon feed is slurried with a particulate solid material to form a heavy hydrocarbon slurry and hydrocracked in a slurry hydrocracking unit to produce vacuum gas oil (VGO) and pitch. A first vacuum column separates VGO from pitch, and a second vacuum column further separates VGO from pitch. As much as 15 wt-% of VGO can be recovered by the second vacuum column and recycled to the slurry hydrocracking unit. A pitch composition is obtained which can be made into particles and transported without sticking together.

It has now been disclosed that by directing the effluent from an oligomerization reactor to a water wash column to remove alcohol modifier from the hydrocarbon stream before sending it to a fractionation column offers flexibility in providing a bottoms product of a desired vapor pressure without increasing the concentration of alcohol modifier in the overhead stream beyond alcohol concentration limits.
