Ubumuncu be-asidi yomphezulu we-ZSM molecular sieve

I-asidi engaphezulu yesihluzo se-molecular se-ZSM yenye yeempawu zayo ezibalulekileyo njenge-catalyst.
Le asidi ivela kwiiathom zealuminiyam ezikwiskeleton yesihluzo semolekyuli, ezinokwenza iiproton zenze umphezulu ofana neproton.
Lo mphezulu uprotonated unokuthatha inxaxheba kwiindlela ezahlukeneyo zeekhemikhali, kubandakanya i-alkylation, i-acylation, kunye nokuphelelwa ngamanzi emzimbeni. I-acidity yomphezulu wesihluzo se-molecular se-ZSM inokulawulwa.
Ubumuncu bomphezulu wesihluzo semolekyuli bunokulawulwa ngokulungelelanisa iimeko zokwenziwa, ezifana ne-Si-

Umlinganiselo we-Al, ubushushu bokwenziwa, uhlobo lwe-template agent, njl. Ukongeza, i-acidity yomphezulu wesihluzo se-molecular inokutshintshwa nangonyango emva konyango, njengokutshintshana kwee-ion okanye unyango lwe-oxidation.
I-asidi yomphezulu we-ZSM molecular seeve inefuthe elibalulekileyo kumsebenzi wayo kunye nokukhetha kwayo njenge-catalyst. Kwelinye icala, i-asidi yomphezulu inokukhuthaza ukusebenza kwe-substrate, ngaloo ndlela ikhawulezise izinga lokuphendula.
Kwelinye icala, i-acidity yomphezulu ingachaphazela ukusasazwa kwemveliso kunye neendlela zokusabela. Umzekelo, kwiimpendulo ze-alkylation, ii-molecular seeves ezine-acidity ephezulu yomphezulu zinokubonelela ngokukhetha okungcono kwe-alkylation.
Ngamafutshane, i-asidi engaphezulu yesihluzo se-molecular se-ZSM yenye yeempawu zayo ezibalulekileyo njenge-catalyst.
Ngokuqonda nokulawula le asidi, kunokwenzeka ukuphucula ukusebenza kwee-molecular seeves kwiindlela ezahlukeneyo zeekhemikhali.
