Abstract
A hydrocarbon containing feed stream, e.g., a heavy oil or residuum, is contacted under suitable reaction conditions with a free hydrogen containing gas and a selenium compound, preferably selenium dioxide, so as to produce a hydrocarbon stream having an increased API.sup.60 gravity. Generally the amounts of impurities (sulfur, coke precursors, metals) contained in the feed stream are reduced in this hydrotreating process.
