HYDROTREATING CATALYSTS COMPRISING MIXTURES OF AN AMORPHOUS SULFIDE OF TRIVALENT CHROMIUM AND MICROCRYSTALLITES OF MOLYBDENUM SULFIDE OR TUNGSTEN

摘要

A composition of matter comprising a mixture of (i) an amorphous sulfide of trivalent chromium and (ii) microcrystallites of metal sulfide of a metal selected from the group consisting of Mo, W and mixture thereof. These compositions have been found to be useful hydrotreating catalysts having nitrogen removal activity superior to that of commercial catalysts derived from cobalt molybdate on alumina.
