Ukusetshenziswa kwe-ZSM ye-molecular sieve njenge-catalyst ye-isomerization

I-ZSM molecular sieve iwuhlobo lwe-crystalline silicaluminate enobukhulu obuhlukile bembotshana nokuma kwayo, esetshenziswe kabanzi ekuphenduleni kwamakhemikhali okuhlukahlukene ngenxa yokusebenza kwayo okuhle kakhulu kwe-catalytic.
Phakathi kwabo, ukusetshenziswa kwe-ZSM ye-molecular sieve emkhakheni we-isomerization catalyst kuye kwakhanga ukunaka okukhulu.
Njenge-catalyst ye-isomerization, isisefo se-molecular ye-ZSM sinezinzuzo ezilandelayo:
1. I-Acidity nokuzinza: Isisefo se-molecular ye-ZSM sine-acidity ephezulu kanye nokuzinza, okunganikeza izimo zokusabela ezifanele futhi kukhuthaze ukusebenza nokuguqulwa kwama-substrates.
2. Ubukhulu bembotshana kanye nokuma: Isisefo se-molecular ye-ZSM sinesayizi eyingqayizivele yembotshana kanye nokuma, okungahlola futhi kwandise ukusakazeka kanye nokuxhumana kwama-reactants kanye nemikhiqizo, ngaleyo ndlela ithuthukise umsebenzi nokukhetha kwe-catalyst.
3. Ukusebenza kwe-modulation: Ngokulungisa izimo zokuhlanganisa kanye nezindlela zangemuva kokucubungula ze-ZSM molecular sieve, ubukhulu bayo bembotshana, ukuma, i-asidi nokuzinza kungalawulwa ukuze kuhambisane nezidingo ezahlukene zokusabela kwe-isomerization.
Ekuphenduleni kwe-isomerization, isisefo se-molecular ye-ZSM sisetshenziswa kakhulu njenge-catalyst ye-isomerization, engakhuthaza ukuguqulwa okuhlangene kwama-substrates futhi ibone ukuhlanganiswa okuphumelelayo kwemikhiqizo.
Isibonelo, emkhakheni we-petrochemical, i-ZSM i-molecular sieve isetshenziswa kabanzi ku-hydrocarbon isomerization, i-alkylation, i-acylation nokunye ukusabela ukuze kuthuthukiswe ikhwalithi kanye nesivuno semikhiqizo ye-petroleum.
Ngamafuphi, i-ZSM molecular sieve, njenge-catalyst enhle kakhulu ye-isomerization, inezinhlobonhlobo zezicelo ku-petrochemical, synthesis ye-organic, ukuvikelwa kwemvelo kanye neminye imikhakha.
Ngocwaningo olwengeziwe nokuthuthukiswa, kungalindelwa ukuthi kudlale indima ebaluleke kakhulu esikhathini esizayo.
