ABSTRACT:
The present invention is directed to a method for producing a crude product from a crude feed. A crude feed is contacted with a hydrogen source and a catalyst comprising a transition metal sulfide under conditions controlled such that the crude product has a residue content of at most the 30% of the residue content of the crude feed.
