Abstract
This invention teaches an improved ebullated-bed reactor hydrotreating/hydrocracking process for treating heavy vacuum gas oil (HVGO) and deasphalted oil (DAO) feeds. The reactor is designed to operate at minimum catalyst bed expansion so as to maximize reactor kinetics and approach plug flow reactor process performance. Further, the invention allows for the production of a uniform product quality and production output that does not substantially vary with time.
