ABSTRACT:
A process for producing diesel fuel from a diesel hydrocarbon feed. Hydrogen is fed cocurrently with the feed to a first hydrogenation zone in the presence of a hydrogenation catalyst. Liquid effluent from the first hydrogenation zone is then passed to a second hydrogenation zone, wherein the liquid effluent is contacted countercurrently with hydrogen in the presence of a hydrogenation catalyst. Preferred hydrogenation catalysts are those comprising non-noble metals in the first hydrogenation zone, and may comprise noble or non-noble metals in the second hydrogenation zone.
