There is disclosed a catalyst, which catalyst comprises a hydrogenation component comprising chromium, molybdenum, and at least one metal of Group VIII, a crystalline molecular sieve zeolite, and a porous refractory inorganic oxide. Suitable molecular sieve zeolites are those having pore diameters of at least 5 ANGSTROM (0.5 nm) and containing exchangeable cations, for example, faujasite-type crystalline alumino silicates, mordenite-type crystalline aluminosilicates, ZSM-type crystalline aluminosilicates, and AMS-type crystalline metallosilicates. There is also disclosed a process which process comprises contacting a hydrocarbon stream containing a substantial amount of nitrogen under hydrotreating conditions and in the presence of hydrogen with the aforesaid catalyst. |
