· J. Catal.; (United States)
Hydrodesulfurization of a 345-525/sup 0/C heavy gas oil, from a thermally cracked Athabasca bitumen, containing 3.59 wt.% sulfur and aromatics with three to six condensed rings on alumina-supported 9 or 12% molybdena promoted with various amounts of zinc showed approximately 65% hydrodesulfurization at 380/sup 0/-450/sup 0/C in bench-scale tests. These results indicate that the cobalt- or nickel-promoted catalysts are more active for hydrodesulfurization, in agreement with de Beer's recent publication.
