I-ZSM-35
Isihlungi sama-molecule se-ZSM-35 sinokuzinza okuhle kokushisa kwamanzi, ukuzinza kokushisa, isakhiwo se-pore kanye ne-asidi efanelekile, futhi singasetshenziswa ekuqhekekeni/ekususeni ama-alkanes ngokukhetha.

I-Zsm-23
Ukwakheka kwamakhemikhali: |na+n (H2O) 4 | [alnsi24-n o48]-mtt, n <2
Isihlungi sama-molecule se-ZSM-23 sinohlaka lwe-MTT topological, oluqukethe amasongo anamalungu amahlanu, amasongo anamalungu ayisithupha kanye namasongo anamalungu ayishumi ngesikhathi esisodwa. Ama-pores anobukhulu obubodwa akhiwe ngamasongo anamalungu ayishumi ayizimbobo ezihambisanayo ezingaxhumene. I-orifice yamasongo anamalungu ayishumi inobukhulu obuthathu obugobile, kanti ingxenye ephambeneyo inomumo we-teardrop.

I-ZSM-22
Ukwakheka kwamakhemikhali: |na+n (H2O) 4 | [alnsi24-no48]-ton, n <2
Uhlaka lwe-ZSM-22 lunesakhiwo se-topological esinobukhulu obuyi-ton, esihlanganisa amasongo anamalungu amahlanu, amasongo anamalungu ayisithupha kanye namasongo anamalungu ayishumi ngesikhathi esisodwa. Amasongo anobukhulu obubodwa akhiwe ngamasongo anamalungu ayishumi ayizimbobo ezihambisanayo ezingaxhumene, kanti i-orifice iyi-elliptical.

Ama-Zeolite akhetha ukuma kochungechunge lwe-ZSM-5
I-ZSM-5 zeolite ingasetshenziselwa imboni ye-petrochemical, imboni yamakhemikhali amahle kanye neminye imikhakha ngenxa yomsele wayo okhethekile we-three-dimensional cross straight pore, ukuqhekeka okukhethekile kokukhetha ukuma, i-isomerization kanye nekhono le-aromatization. Okwamanje, zingasetshenziswa ku-catalyst ye-FCC noma izithasiselo ezingathuthukisa inombolo ye-octane kaphethiloli, ama-catalyst e-hydro/aonhydro dewaxing kanye ne-unit process xylene isomerization, i-toluene disproportionation kanye ne-alkylation. Inombolo ye-octane kaphethiloli ingathuthukiswa futhi okuqukethwe kwe-olefin kungakhushulwa uma ama-zeolite engezwa ku-catalyst ye-FCC ku-FBR-FCC reaction. Enkampanini yethu, ama-zeolite e-ZSM-5 serial shape-selective anesilinganiso esihlukile se-silica-alumina, kusukela ku-25 kuya ku-500. Ukusatshalaliswa kwezinhlayiya kungalungiswa ngokuya ngezidingo zamakhasimende. Amandla e-isomerization kanye nokuzinza komsebenzi kungashintshwa lapho i-acidity ilungiswa ngokushintsha isilinganiso se-silica-alumina ngokuya ngezidingo zakho.
