ZSM-5 uhlobo zeolite, endingowakhe ophezulu-dust zeolite nokuba Si / Al Umlinganiselo ukuya ku-1000 kwaye ngasentla, naye ubonisa uphawu hydrophobic. Ubume mpawu zeolite kukuba kwiindawo ezithe nkqo nkqo ukuba crystalline alum inosilicate eyakhiwa yejelo 10 membered-. Isakhiwo esingundoqo ubunjwe ezisibhozo amakhonkco-5-membered, nto leyo eye imijelo kuphela kwaye ngaphandle nemingxuma ebuhlanti-free. ZSM-5 uye iiseti ezimbini lamajelo umnqamlezo, enye yazo na ellipse, kwaye window ubukhulu bayo 0,55 ukuya 0.60nm. Njengokuba isithuba abasabela iyafana imilo ufikelelo, lo zeolite lubanesiphumo ukhetho imilo ukuya reactants kunye nemveliso. Ngaphezu koko, ZSM-5 kuyinto material elungileyo ekrwada of iza uyakhetha ngenxa isakhiwo kolwandle uzinzo ivumelane.
ZSM-5 uhlobo zeolite lisetyenziswa kwi mveliso petrochemical processing, isicelo fluidifying, catalyzing kunye nenkqubo ngokuhlaziya nje ngeqela yokuvelisa propylene ngakumbi irhasi yohlobo lwepetroliyam, nokuphucula inani octane le zepetroli. Ukongeza, le zeolite linokusetyenziswa ukuveliswa ethylbenzene, xylene, phenol, pyridine, njl
Yesicelo:
1.ZSM - 5 yokugalela ezinto ezisetyenziswa FCC kuvala: eqhelekileyo SiO2 / Al2O3 ratio luphakathi-40 ukuya ku-50
2.ZSM - 5 yokugalela molekyuli esetyenziselwa FCC ongeziweyo ipetroli ukunciphisa olefin: eqhelekileyo SiO2 / Al2O3 ratio ephakathi 38 ukuya 40.
3.ZSM - 5 yokugalela molekyuli zisetyenziselwa resid nokuqhekeka zokuphosa: eqhelekileyo SiO2 / Al2O3 ratio luphakathi 25 ukuya 30.
4.ZSM - 5 ukusefa eziphilayo kushishino weekhemikhali, ishishini yemichiza ecikizekileyo lisetyenziswa kwimilo-uyakhetha catalysis, ezifana diethylbenzene ngumnxibelelanisi, iza xylene isomerization, ethyl acetate, ethylene ethers, ethylene ethers butyl kaEtere of iza enoluhlu olubanzi zosetyenziso.
