Zsm-23
Abubuwan sinadaran: |na+n (H2O) 4 | [alnsi24-n o48] -mtt, n <2
ZSM-23 molecular sieve yana da tsarin MTT topological, wanda ya ƙunshi zobba biyar masu gemu, zobba shida masu gemu da zobba goma masu gemu a lokaci guda. Pores masu gemu ɗaya waɗanda aka haɗa da zobba goma masu gemu ramuka ne masu layi ɗaya waɗanda ba su da alaƙa da juna. Murfin zobba goma masu gemu yana da girma uku, kuma sashin giciye yana da siffar hawaye.

ZSM-22
Abubuwan sinadaran: |na+n (H2O) 4 | [alnsi24-no48] -ton, n <2
Kwakwalwar ZSM-22 tana da tsari mai yawa na yanayin ƙasa, wanda ya haɗa da zobba biyar masu gefuna, zobba shida masu gefuna da zobba goma a lokaci guda. Zuraran da ke da girma ɗaya da aka yi da zobba goma masu gefuna ramuka ne masu layi ɗaya waɗanda ba su da alaƙa da juna, kuma wurin da aka yi wa ado yana da siffar ellipse.

Zeolites masu zaɓin siffar ZSM-5
Ana iya amfani da zeolite na ZSM-5 don masana'antar mai, masana'antar sinadarai masu kyau da sauran fannoni saboda magudanar rami mai kusurwa uku mai girma, fashewar siffofi na musamman, isomerization da iyawar aromatization. A halin yanzu, ana iya amfani da su ga mai kara kuzari na FCC ko ƙari waɗanda za su iya inganta adadin octane na gasoline, masu kara kuzari na hydro/aonhydro dewaxing da kuma isomerization na xylene naúrar, rashin daidaiton toluene da alkylation. Ana iya haɓaka lambar octane na gasoline kuma ana iya ƙara yawan olefin idan an ƙara zeolites zuwa mai kara kuzari na FCC a cikin amsawar FBR-FCC. A cikin kamfaninmu, zeolites na siffa-zaɓin ZSM-5 suna da rabo daban-daban na silica-alumina, daga 25 zuwa 500. Ana iya daidaita rarraba barbashi bisa ga buƙatun abokan ciniki. Ana iya canza ikon isomerization da kwanciyar hankali na aiki lokacin da aka daidaita acidity ta hanyar canza rabon silica-alumina bisa ga buƙatunku.
