Zeolite n-gun dat USY (Ultra-Stable Y) shing nrai USY molecular sieve ngu ai gaw NaY n-gun dat hpe ion galai shai ai lam hte n-gun dat n-gun dat ai hku nna galai shai ai hku nna lu la ai Y-hpan n-gun dat n-gun dat amyu langai mi re. FAU hkrang masa hpan zeolite hta lawm nna, NaY zeolite hte maren hkrang masa nga ai. Shi a pore diameter gaw 0.74 nm daram rai nna, shi a hkrang gaw hpraw ai powder rai nga ai.
NaY zeolite molecular sieve hte shingdaw yu yang, USY gaw npu na framework aluminum n-gun (Si/Al ratio grau law ai), n-gun hte hka n-gun grau kaja ai, n-gun grau kaja ai n-gun rawng ai. USY molecular sieve hpe madung hku nna n-gun jat ai lam hta jai lang ai rai nna, dai ni na aten na FCC n-gun jat ai lam ni a core active component rai nga ai.
Shi a hkrang masa ngang grin ai hte acid hpe hkang lu ai atsam ni hte, USY molecular sieve gaw, petrochemical hpaga lam hta catalytic n-gun atsam hte arung arai lata la ai lam hpe grai jat wa shangun nna, shi hkum shi n mai galai shai ai, grau nna sau kaba galaw shapraw ai hte n law ai-carbon hydrocarbon galai shai ai lam ni hta.
