I-ZSM ye-molecular sieve luhlobo lwe-crystalline silicaluminate enobukhulu obukhethekileyo bepore kunye nemilo, esetyenziswe ngokubanzi kwiindlela ezahlukeneyo zeekhemikhali ngenxa yokusebenza kwayo okuhle kakhulu.
Phakathi kwabo, ukusetyenziswa kwe-ZSM ye-molecular sieve kwintsimi ye-catalyst ye-isomerization kuye kwatsala ingqalelo enkulu.
Njenge-catalyst ye-isomerization, i-ZSM ye-molecular sieve inezi zibonelelo zilandelayo:
1. I-Acidity kunye nokuzinza: I-ZSM i-molecular sieve ine-acidity ephezulu yomhlaba kunye nokuzinza, enokubonelela ngeemeko ezifanelekileyo zokuphendula kunye nokukhuthaza ukusebenza kunye nokuguqulwa kwe-substrates.
2. Ubungakanani bepore kunye nokuma: I-ZSM i-molecular sieve inobungakanani obukhethekileyo kunye nokuma kwe-pore, enokuthi ikhusele kwaye ikhulise ukusabalalisa kunye nokudibanisa kwee-reactants kunye neemveliso, ngaloo ndlela iphucula umsebenzi kunye nokukhetha kwe-catalyst.
3. Ukusebenza kokumodareyitha: Ngokuhlengahlengisa iimeko zokudibanisa kunye neendlela zasemva kokulungiswa kwe-ZSM ye-molecular sieve, ubukhulu bayo be-pore, imilo, i-acidity kunye nokuzinza kunokulawulwa ukulungelelanisa iimfuno ezahlukeneyo zokusabela kwe-isomerization.
Kwimpendulo ye-isomerization, isihluzo semolekyuli ye-ZSM sisetyenziswa ikakhulu njenge-isomerization catalyst, enokukhuthaza ukuguqulwa okulinganayo kwee-substrates kunye nokuqonda ukuhlanganiswa okusebenzayo kweemveliso.
Ngokomzekelo, kwintsimi ye-petrochemical, i-ZSM ye-molecular sieve isetyenziswa ngokubanzi kwi-hydrocarbon isomerization, i-alkylation, i-acylation kunye nezinye iimpendulo zokuphucula umgangatho kunye nesivuno seemveliso zepetroleum.
Ngamafutshane, i-ZSM ye-molecular sieve, njenge-catalyst ye-isomerization egqwesileyo, inoluhlu olubanzi lwezicelo kwi-petrochemical, i-organic synthesis, ukhuseleko lokusingqongileyo kunye nezinye iinkalo.
Ngophando olongezelelweyo kunye nokuphuculwa, kunokulindeleka ukuba kudlale indima ebaluleke ngakumbi kwixesha elizayo.
