Abstract
Hydrodesulfurization and demetallalization of hydrocarbon charge is effected by hydrogenation in the presence of, as catalyst, a Group VI A metal and a non-noble Group VIII metal on a trimodal alumina support. The alumina support is formed by mixing at least two different finely divided charge aluminas each of which has a different pore mode.
