ABSTRACT:
A catalyst composition for hydrotreating of hydrocarbon oils is disclosed. The composition comprises a Group VIB metal in an amount of 5-30% by weight, as oxide, and a Group VIII metal in an amount of 1-10% by weight, as oxide, wherein said Group VIB metal and said Group VIII metal are distributed with a concentration gradient which becomes higher from the surface toward the center of a catalyst particle according to the formulas, 0.9>h.sub.2 /h.sub.1 .gtoreq.0, wherein h.sub.1 is the Group VIB metal concentration at the center of the catalyst particle and h.sub.2 at the outermost surface of the catalyst particle, and 0.9>h.sub.4 /h.sub.3 .gtoreq.0, wherein h.sub.3 is the Group VIII metal concentration at the center of the catalyst particle and h.sub.4 at the outermost surface of the catalyst particle. The catalyst composition can be used for hydrodesulfurization, hydrodenitrification, hydrodemetalization, and hydrocracking of topping or vacuum distillates and residues, as well as hydrotreatments for the refining of such fractions as kerosene, gas oil, wax, and lubricating oil. It exhibits a high activity for a prolonged period of time. Processes for manufacturing the catalyst composition are also disclosed.
