Abstract
An integrated residuum hydroconversion process which includes a residuum hydrotreater and a desulfurized oil hydrocracker produces high quantities of high quality middle distillate fuels. Distillate range products from the residuum hydrotreater are hydrocracked, while catalyst fouling from heavy aromatics present in the hydrotreated products is minimized. The process includes a single hydrogen supply and recovery loop for increased cost and energy savings.
