Abstract
Hydrocarbon feedstocks are selectively hydrodesulfurized by contacting the feedstock in the presence of hydrogen with a predecessor catalyst comprising molybdenum or tungsten sulfide which has been promoted by reaction with a transition metal containing organo-metallic complex wherein the valence of the metal is 0 or +1 at the time of reaction and the contacting is done at a temperature and pressure sufficient to substantially hydrodesulfurize the hydrocarbon.
