Zeolite catalyst RE-USY (Rare Earth exchanged Ultra-Stable Y) anaa RE-USY molecular sieve, wonya denam nsakrae a wɔyɛ wɔ USY zeolite denam ion exchange a wɔne asase so ions a wɔntaa nhu te sɛ La yɛ so3+ne Ce3+. Ɛka USY hyew ne nsuo a ɛyɛ den a ɛkorɔn no ne acidity ne structure stability a ɛkɔ soro a ɛfiri asase mu nsakraeɛ a ɛntaa nsi-mu ba no bom.
RE-USY molecular sieve wɔ FAU topology, a ɛkyerɛ su 12-membered ring channels ne supercage nhyehyɛe akɛse.
