Abstract
A hydrogenation catalyst including a carrier of ultrastable zeolite Y modified with at least one heavy rare earth element selected from ytterbium, gadolinium, terbium and dysprosium. At least one catalytic metal selected from palladium and platinum is supported on the carrier. A process for hydrogenating a feed containing an aromatic and/or a heterocyclic aromatic compound includes a step of contacting the feed with hydrogen in the presence of the above hydrogenation catalyst.
