Hydrotreating with catalysts comprising mixtures of an amorphous sulfide or trivalent chromium and microcrystallites of molybdenum sulfide or tungsten sulfide
A process is described for hydrorefining a hydrocarbon feed to reduce the contents of nitrogen compounds and sulfur compounds in the feed which comprises contacting the feed at an elevated temperature of at least about 150/sup 0/C and in the presence of hydrogen with a catalyst consisting essentially of a mixture of (i) an amorphous sulfide of trivalent chromium and (ii) microcrystallities of a metal sulfide of a metal selected from the group consisting of Mo, W and mixture thereof, the contacting occurring for a time sufficient to hydrorefine at least a portion of the feed. The patent also describes a process for improving the oxidation stability of a nitrogen and sulfur containing lube oil feed which comprises contacting the feed at an elevated temperature of at least about 150/sup 0/C and in the presence of hydrogen with a catalyst consisting essentially of a mixture of (i) an amorphous sulfide of trivalent chromium and (ii) microcrystallities of metal sulfides of a metal selected from the group consisting of Mo, W and mixture thereof, the contacting occurring for a time sufficient to improve the oxidation stability of the lube oil feed.
