ZSM molecular sieve ndi mtundu wa silicaluminate wa crystalline wokhala ndi kukula kwake ndi mawonekedwe a pore, omwe amagwiritsidwa ntchito kwambiri pamachitidwe osiyanasiyana amankhwala chifukwa cha magwiridwe ake abwino kwambiri.
Mwa iwo, kugwiritsa ntchito ZSM maselo sieve m'munda wa isomerization chothandizira wakopa chidwi kwambiri.
Monga chothandizira cha isomerization, sieve ya molekyulu ya ZSM ili ndi zotsatirazi:
1. Acidity ndi bata: ZSM maselo sieve ali mkulu padziko acidity ndi bata, amene angapereke zinthu zoyenera anachita ndi kulimbikitsa kutsegula ndi kusintha magawo.
2. Pore kukula ndi mawonekedwe: ZSM maselo sieve ali wapadera pore kukula ndi mawonekedwe, amene akhoza zenera ndi konza mayamwidwe ndi kukhudzana reactants ndi mankhwala, potero kuwongolera ntchito ndi selectivity wa chothandizira.
3. Kusinthasintha ntchito: Ndi kusintha zinthu kaphatikizidwe ndi pambuyo processing njira ZSM maselo sieve, pore kukula kwake, mawonekedwe, acidity ndi bata akhoza lizilamuliridwa kuti azolowere osiyana isomerization amafuna anachita.
Mu zochita za isomerization, ZSM molecular sieve imagwiritsidwa ntchito ngati chothandizira cha isomerization, chomwe chimatha kulimbikitsa kutembenuka kwa magawo ndi kuzindikira kaphatikizidwe koyenera kwa zinthu.
Mwachitsanzo, m'munda wa petrochemical, ZSM molekyulu sieve chimagwiritsidwa ntchito hydrocarbon isomerization, alkylation, acylation ndi zina zimachitikira kusintha khalidwe ndi zokolola za mafuta mafuta.
Mwachidule, ZSM molekyulu sieve, monga chothandizira kwambiri isomerization, ali osiyanasiyana ntchito petrochemical, kaphatikizidwe organic, kuteteza chilengedwe ndi zina.
Ndi kafukufuku wowonjezereka ndi kusintha, zikhoza kuyembekezera kukhala ndi gawo lofunika kwambiri m'tsogolomu.
