Ubumuncu obuphezulu be-ZSM ye-molecular sieve

I-acidity engaphezulu ye-ZSM ye-molecular sieve yenye yeempawu zayo ezibalulekileyo njenge-catalyst.
Le asidi ivela kwiiathom ze-aluminiyam kwi-molecular sieve skeleton, enokubonelela ngeeprotons ukwenza umphezulu weprotonated.
Lo mphezulu weprotonated unokuthatha inxaxheba kwiintlobo ezahlukeneyo zeekhemikhali, kuquka i-alkylation, i-acylation, kunye nokuphelelwa ngamanzi emzimbeni.Ubumuncu obungaphezulu be-ZSM ye-molecular sieve bunokulawulwa.
I-acidity engaphezulu ye-molecular sieve inokulawulwa ngokulungelelanisa iimeko zokudibanisa, ezifana ne-Si-

Umlinganiselo we-Al, ubushushu be-synthesis, uhlobo lwe-agent ye-template, njl. Ukongeza, i-acidity yomhlaba we-molecular sieve ingatshintshwa kwakhona nge-post-treatment, njengokutshintsha kwe-ion okanye unyango lwe-oxidation.
I-acidity engaphezulu ye-ZSM ye-molecular sieve inefuthe elibalulekileyo kumsebenzi wayo kunye nokukhetha njengento ekhuthazayo.Kwelinye icala, i-asidi yomphezulu inokukhuthaza ukusebenza kwe-substrate, ngaloo ndlela inyusa isantya sokuphendula.
Kwelinye icala, ubumuncu bomphezulu bunokuchaphazela ukuhanjiswa kwemveliso kunye neendlela zokusabela.Ngokomzekelo, kwiimpendulo ze-alkylation, i-molecular sieves ene-acidity ephezulu yendawo inokubonelela ngokukhetha okungcono kwe-alkylation.
Ngamafutshane, i-acidity engaphezulu ye-ZSM ye-molecular sieve yenye yeempawu zayo ezibalulekileyo njenge-catalyst.
Ngokuqonda kunye nokulawula le acidity, kunokwenzeka ukwandisa ukusebenza kwe-molecular sieves kwiindlela ezahlukeneyo zeekhemikhali.
