ABSTRACT:
A proces for hydrocracking 343.degree. C..sup.+ feedstock which contains polycyclic aromatics to form a lube base stock having enhanced oxidation stability and viscosity index is disclosed. The process employs a catalyst which comprises a layered silicate, such as magadiite which contains interspathic polymeric silica and interspathic polymeric oxides of one or more elements selected from the group consisting of Al, B, Cr, Ga, In, Mo, Nb, Ni, Ti, Tl, W and Zr, preferably Al. The catalyst may also contain a hydrogenation component, e.g., palladium.
