Decision tree helps select hydrotreating catalyst, as is shown by use of the decision tree to select between Shell 324, a second-generation nickel/molybdenum catalyst, and Shell 344, a second-generation cobalt/molybdenum catalyst, in a number of applications, including the desulfurization of a vacuum gas oil to 0.1% by wt product sulfur for a straight-run feedstock, desulfurization of a flashed distillate, denitrogenation, hydrotreating a gas oil for fluid catalytic cracker feed, and denitrogenation and H/sub 2/ uptake for cracked stocks. Operating data reported in the literature support the catalyst choices indicated by the decision tree. The decision tree does not indicate a preferred catalyst in cases involving desulfurization and denitrogenation of a straight run to given levels, and the hydrotreating for desulfurization of cracked stocks. Cracked stock processing difficulties, which sometimes require that a catalyst other than the preferred catalyst be used, are discussed.
