Abstract
A catalyst, prepared by supporting a catalytic effective amount of hydrogenation metal on a catalyst carrier material comprising zeolite and an amorphous inorganic oxide and further incorporating 1-15 wt % of sulfate anions therein, is effective as a hydrotreating catalyst for producing an intermediate fraction with a high yield by desulfurization, demetallization and dentrification of heavy oils.
