ZSM-5 nooca zeolite, tirsan zeolite-silica sare iyo a ratio Si / Al ilaa 1000 iyo wixii ka sareeya, sidoo kale waxa ay muujinaysaa dabeecadda hydrophobic. feature The dhismeedka of zeolite noocan oo kale ah waa in qaybaha joog iyo jiif waa inosilicate alum crystalline ka kooban channel 10-membered. Qaab-dhismeedka aasaasiga ah ee ka kooban yahay siddeed siddo 5-membered, taas oo uu leeyahay channels kaliya oo aan godadka qafis-free. ZSM-5 waxay leedahay laba nooc oo channels cross, mid ka mid ah taas oo ah ellipse, iyo dhexroor daaqadda waa 0.55 si 0.60nm. Sida meel falcelinta la mid tahay qaabka ay helaan, zeolite waxay leedahay saameyn qaabka doorashada u reactants iyo alaabta a. Waxaa intaa dheer, ZSM-5 waa wax wanaagsan cayriin ee Hannaan xushay ay sabab u tahay qaabka iyo hydrothermal xasiloonida habboonaanta.
ZSM-5 nooca zeolite waxaa si balaadhan looga codsadaa in ay warshado processing kiimikada, codsatay in fluidifying ah, catalyzing iyo habka arrinkaas sida kaaliye soo saarka propylene dheeraad ah iyo gaaska la galeen, iyo hagaajinta tiro falkaas xun ee shidaalka ah. Intaa waxaa dheer, zeolite ee lagu saleyn karaa wax soo saarka ee ethylbenzene, xylene, phenol, pyridine, iwm
Codsiga:
1.ZSM - 5 shaandho kelli loo isticmaalo Hannaan FCC: caadiga ratio SiO2 / Al2O3 waa inta u dhaxaysa 40 ilaa 50.
2.ZSM - 5 shaandho kelli loo isticmaalo daro baatrool FCC si loo yareeyo olefin ah: caadiga ratio SiO2 / Al2O3 waa inta u dhaxaysa 38 si 40.
3.ZSM - 5 shaandho kelli loo isticmaalo arrinkaas horseed resid: caadiga ratio SiO2 / Al2O3 waa inta u dhaxaysa 25 ilaa 30.
4.ZSM - 5 finjilka kelli in industry kiimikada, warshadaha kiimikada wanaagsan waxaa si balaadhan looga isticmaalaa in catalysis qaab-xulashada, sida Hannaan diethylbenzene, Hannaan isomerization xylene, copolymer ethyl, tones ethylene, ethylene ether butyl tones of Hannaan uu leeyahay tiro balaadhan oo ah isticmaalka.
