I-ZSM-5 i-zeolite ingase isetshenziselwe imboni ye-petrochemical, imboni yamakhemikhali emihle kanye neminye imikhakha ngenxa ye-pore canal ekhethekile enezinhlangothi ezintathu eziqondile, ukuqhekeka okukhethekile okukhetha ukuma, i-isomerization kanye nekhono lokuphunga. Okwamanje, zingasetshenziswa ku-FCC catalyst noma izithasiselo ezingathuthukisa inombolo ye-octane kaphethiloli, ama-hydro/aonhydro dewaxing catalysts kanye neyunithi yenqubo ye-xylene isomerization, ukungalingani kwe-toluene kanye ne-alkylation. Inombolo ye-octane kaphethiloli ingathuthukiswa futhi okuqukethwe kwe-olefin nakho kungandiswa uma ama-zeolite engezwa ku-catalyst ye-FCC ekuphenduleni kwe-FBR-FCC. Enkampanini yethu, i-ZSM-5 i-serial shape-selective zeolite inesilinganiso esihlukile se-silica-alumina, kusukela ku-25 kuya ku-500. Ukusatshalaliswa kwezinhlayiyana kungalungiswa ngokuvumelana nezidingo zamakhasimende. Ikhono le-isomerization nokuzinza komsebenzi kungashintshwa lapho i-asidi ilungiswa ngokushintsha isilinganiso se-silica-alumina ngokuya ngezidingo zakho.
