Maselo sieve ZSM

ZSM-5 mtundu zeolite, ndiwe wa mkulu-silika zeolite ndi kukhala Si / Al chiŵerengero cha ku 1000 ndipo pamwamba, limasonyezanso khalidwe hydrophobic. Kapangidwe Mbali imeneyi zeolite ndi mbali ofukula ndi yopingasa ndi crystalline alum inosilicate wapangidwa 10-ziwalo njira. Kapangidwe zofunika wapangidwa ndi zisanu ndi zitatu mphete 5-ziwalo, amene ali njira yokha ndipo popanda cavities khola-free. ZSM-5 ali miyeso iwiri njira mtanda, mmodzi amene ali ellipse, ndi zenera awiri kwake 0,55 kuti 0.60nm. Monga danga anachita ndi ofanana ndi mawonekedwe a mwayi, ndi zeolite ali ndi mawonekedwe kusankha zotsatira za reactants ndi mankhwala. Komanso, ZSM-5 ndi zabwino zopangira wa chothandizira kusankha chifukwa zogwirizana kapangidwe ndi Madziwo bata.

ZSM-5 mtundu zeolite chimagwiritsidwa ntchito kwa mafakitale petrochemical processing ntchito kwa fluidifying ndi, catalyzing ndi akulimbana ndondomeko yothandiza yopangira propylene ndi gasi liquefied, ndi kuwongolera octeni chiwerengero cha mafuta. Komanso, zeolite ingagwiritsidwe ntchito yopanga ethylbenzene, xylene, phenol, pyridine, etc.

Ntchito:
1.ZSM - 5 maselo sieve ntchito FCC chothandizira: ochiritsira SiO2 / Al2O3 chiŵerengero ndi pakati pa 40 ndi 50.
2.ZSM - 5 sieve maselo ntchito FCC mafuta zina kuchepetsa olefin: ochiritsira SiO2 / Al2O3 chiŵerengero ndi pakati pa 38 kuti 40.
3.ZSM - 5 sieve maselo ntchito resid othandizira akulimbana: ochiritsira SiO2 / Al2O3 chiŵerengero ndi pakati pa 25 mpaka 30.
4.ZSM - 5 sieves maselo makampani mankhwala, makampani chabwino mankhwala chimagwiritsidwa ntchito mu mawonekedwe-kusankha catalysis, monga chothandizira diethylbenzene, xylene isomerization chothandizira, ethyl nthochi, ethylene glycol, ethylene glycol butyl efa wa chothandizira ali osiyanasiyana ntchito.
