Hydroprocessing, encompassing hydrotreating, hydrorefining and hydrocracking are integral elements of the modern refinery. Harsher demands are placed on product-upgrading technology as refiners reach deeper into the barrel of oil to obtain value-added products. Zero-sulfur specs on naphtha feedstocks for reformers, EPA-mandated diesel sulfur and aromatic limits, a growing demand for severly hydrotreated lube oil stocks, and numerous process changes in gasoline production are some of the issues leading refiners to scrutinize operations in order to maximize efficiency. Several methods of catalyst presulfiding are available to refiners. A wide variety of labile organosulfur compounds can be used as agents for vapor-phase or spiked-feed treatments. Sour feedstocks and refinery H/sub 2/S can also be used. The advantages and disadvantages of these various options are reviewed within the text of this paper.
