Abstract
An improved ebullated bed hydroconversion process is disclosed that utilizes a bimodal heterogeneous catalyst and a metal containing oil-miscible-catalysts compound to achieve a reduction in sediment, an increase in conversion, a reduction in the energy utilized to maintain reaction conditions and increases the stability of the ebullated catalyst bed. The oil-miscible compound may be provided in a concentration so as to provide about 1 to about 60 wppm metal based on the charge hydrocarbon oil.
