Zeolite catalyst USY (Ultra-Stable Y) anaa USY molecular sieve yɛ Y-type zeolite bi a wonya denam NaY zeolite a wɔsesa denam ion exchange ne ɔhyew a ɛkorɔn-dealumination a wɔsesa so. Ɛyɛ FAU structure type of zeolite no dea, na ɛwɔ structure koro no ara ne NaY zeolite. Ne pore diameter bɛyɛ 0.74 nm, na ne hwɛbea yɛ powder fitaa.
Sɛ wɔde toto NaY zeolite molecular sieve ho a, USY wɔ framework aluminium a ɛba fam (Si/Al ratio a ɛkorɔn), ɔhyew ne nsuo a ɛyɛ den a ɛyɛ papa, ne catalytic adwumayɛ a ɛkorɔn. USY molecular sieve na wɔde di dwuma titiriw wɔ catalytic field, na ɛyɛ core active component a ɛwɔ nnɛyi FCC catalysts mu.
Ɛnam ne nhyehyɛɛ a ɛgyina pintinn ne acid nhyehyɛeɛ tumi nti, USY molecule sieve ma catalytic efficiency ne product selectivity nya nkɔsoɔ kɛseɛ wɔ petrochemical adwumayɛ mu, na ɛma ɛyɛ nea wontumi nsi ananmu, titire wɔ ngo a emu yɛ duru a wɔyɛ ne low-carbon hydrocarbon conversion mu.
