Abstract
A process for the hydrorefining of hydrocarbon feed to reduce the contents of sulfur and nitrogen compounds therein is disclosed which comprises contacting the hydrocarbon feed at elevated temperatures of at least about 150.degree. C. in the presence of hydrogen with a catalyst consisting essentially of 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.
