Abstract
A hydroconversion process is described in which a feed slurry comprising a heavy hydrocarbon oil and an iron compound additive is contacted with a hydrogen-containing gas in a hydroconversion zone at hydroconversion conditions to convert at least a portion of said oil to lower boiling products. The process is characterized by the use of an iron compound having particle sizes of less than 45 .mu.m, preferably with at least 50 wt % of particles of less than 5 .mu.m.
