摘要
A composition of matter comprising a mixture of (i) a sulfide of at least one promoter metal selected from the group consisting of Ni, Co, Mn, Cu, Zn and mixture thereof and mixtures thereof with Fe, (ii) an amorphous sulfide of trivalent chromium and (iii) microcrystallites of metal sulfide of a metal selected from the group consisting of molybdenum, tungsten and mixture thereof. These compositions have been found to be useful hydrotreating catalysts having nitrogen removal activity superior to that of commercial catalysts such as cobalt-molybdate on alumina.
