I-acidity engaphezulu ye-ZSM molecular sieve

I-acidity engaphezulu ye-ZSM ye-molecular sieve ingenye yezakhiwo zayo ezibalulekile njenge-catalyst.
Le acidity ivela kuma-athomu e-aluminium kuhlaka lwamathambo lwesisefo, olunganikeza ama-proton ukuze akhe indawo ene-protonated.
Le ndawo ene-protonated ingabamba iqhaza ekuphenduleni kwamakhemikhali okuhlukahlukene, okuhlanganisa i-alkylation, i-acylation, kanye nokuphelelwa amandla kwamanzi. I-acidity engaphezulu ye-ZSM ye-molecular sieve ingalawulwa.
I-acidity engaphezulu yesisefo samangqamuzana ingalawulwa ngokulungisa izimo zokuhlanganisa, njenge-Si-

Isilinganiso se-Al, izinga lokushisa le-synthesis, uhlobo lwe-ejenti yesifanekiso, njll. Ngaphezu kwalokho, i-asidi engaphezulu yesisefo samangqamuzana nayo ingashintshwa ngokwelashwa ngemva kokwelashwa, njengokushintshisana kwe-ion noma ukwelashwa kwe-oxidation.
I-acidity engaphezulu ye-ZSM ye-molecular sieve inomphumela obalulekile emsebenzini wayo kanye nokukhetha njengento ekhuthazayo. Ngakolunye uhlangothi, i-acidity engaphezulu ingakhuthaza ukusebenza kwe-substrate, ngaleyo ndlela kusheshise izinga lokuphendula.
Ngakolunye uhlangothi, i-asidi engaphezulu ingase ithinte ukusabalalisa komkhiqizo nezindlela zokusabela. Isibonelo, ekuphenduleni kwe-alkylation, ama-sieve e-molecular ane-acidity ephezulu anganikeza ukukhetha okungcono kwe-alkylation.
Ngamafuphi, i-acidity engaphezulu ye-ZSM molecular sieve ingenye yezakhiwo zayo ezibalulekile njenge-catalyst.
Ngokuqonda nokulawula le acidity, kungenzeka ukwandisa ukusebenza kwezisefo zamangqamuzana ekuphenduleni kwamakhemikhali okuhlukahlukene.
