ZSM-5 irin zeolite, na high-silica zeolite da ciwon Si / Al rabo daga sama zuwa 1000, kuma a sama, kuma ya nuna da hydrophobic halayyar. A tsarin fasalin irin wannan zeolite ne cewa a tsaye da kuma a kwance sassa su ne crystalline alum inosilicate hada da 10-membered tashar. Ainihin tsarin da aka hada da takwas 5-membered zobba, wanda yana da tashoshi kawai kuma shi ne ba tare da keji-free cavities. ZSM-5 yana da biyu sets giciye tashoshi, daya daga wanda ke ellipse, da taga diamita daga gare shi ne 0,55 zuwa 0.60nm. Kamar yadda dauki sarari ne mai kama da siffar da damar, da zeolite yana da wani siffar selection sakamako ga reactants da kayayyakin. Bugu da ƙari, ZSM-5 ne mai kyau albarkatun kasa na zabe mai kara kuzari saboda da jitu tsarin da hydrothermal kwanciyar hankali.
ZSM-5 irin zeolite ne yadu amfani da petrochemical aiki masana'antu, amfani da fluidifying, tsara da kuma aiwatar da fatattaka a matsayin mataimakin domin samar da karin propylene da liquefied gas, da kuma inganta da Octane yawan da fetur. Bugu da kari, da zeolite za a iya amfani da su wajen samar da ethylbenzene, xylene, phenol, pyridine, da dai sauransu
Application:
1.ZSM - 5 kwayoyin sieve amfani ga FCC kara kuzari: al'ada SiO2 / Al2O3 rabo ne tsakanin 40 zuwa 50.
2.ZSM - 5 kwayoyin sieve amfani ga FCC fetur Additives don rage olefin: al'ada SiO2 / Al2O3 rabo ne tsakanin 38 to 40.
3.ZSM - 5 kwayoyin sieve amfani ga resid catalytic fatattaka: al'ada SiO2 / Al2O3 rabo ne tsakanin 25 zuwa 30.
4.ZSM - 5 kwayoyin sieves a sinadaran masana'antu, lafiya sinadaran masana'antu ne yadu amfani a cikin siffar-zabe catalysis, kamar diethylbenzene kara kuzari, xylene isomerization kara kuzari, ethyl acetate, ethylene glycol, ethylene glycol butyl ether na kara kuzari yana da fadi da kewayon amfani.
