Hydrotreating catalysts comprising a mixture of a sulphide of a promoter metal, amorphous sulphide of trivalent chromium and microcrystalline molybdenum or tungsten sulphide.

摘要

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