ZSM-35
ʻO ZSM-35 molecular sieve he hydrothermal stability, thermal stability, pore structure a me ka acidity kūpono, a hiki ke hoʻohana ʻia no ka haʻi ʻana/isomerization o nā alkanes.

ZSM-48
ʻO ZSM-48 molecular sieve he hydrothermal stability, thermal stability, pore structure a me ka acidity kūpono, a hiki ke hoʻohana ʻia no ka haʻi ʻana/isomerization o nā alkanes.

Zsm-23
Huina kemika: |na+n (H2O) 4 | [alnsi24-n o48]-mtt, n < 2
ZSM-23 molecular sieve he MTT topological framework, nona nā apo lālā ʻelima, ʻeono apo lālā a me ʻumi apo lālā i ka manawa like. ʻO nā pores hoʻokahi-dimensional i haku ʻia me nā apo lālā he ʻumi, he pores like ʻole i hoʻopili ʻole ʻia kekahi me kekahi. ʻO ka puka o nā apo lālā ʻumi he ʻano nalu ʻekolu, a ʻo ka ʻāpana keʻa he ʻano waimaka.

ZSM-22
Huina kemika: |na+n (H2O) 4 | [alnsi24-no48]-ton, n < 2
ʻO ka ZSM-22 skeleton he ton topological structure, e komo pū ana me ʻelima mau apo lālā, ʻeono apo lālā a me ʻumi mau apo i ka manawa like. ʻO nā pores hoʻokahi-dimensional i haku ʻia me nā apo he ʻumi, he pores parallel ʻaʻole i hoʻopili ʻia kekahi me kekahi, a he elliptical ka puka.

ZSM-5 moʻo Zeolites koho
Hiki ke hoʻohana ʻia ʻo ZSM-5 zeolite no ka ʻoihana petrochemical, ʻoihana kemika maikaʻi a me nā māla ʻē aʻe ma muli o kāna ʻano ʻekolu-dimensional cross straight pore canal, kūikawā shape-choliability crackability, isomerization a me ka hiki ke aromatization. I kēia manawa, hiki iā lākou ke hoʻopili i ka FCC catalyst a i ʻole nā mea hoʻohui e hiki ke hoʻomaikaʻi i ka helu octane gasoline, hydro/aonhydro dewaxing catalysts a me ke kaʻina hana xylene isomerization, toluene disproportionation a me alkylation. Hiki ke hoʻonui ʻia ka helu octane gasoline a hiki ke hoʻonui ʻia ka ʻike olefin inā hoʻohui ʻia nā zeolites i ka catalyst FCC i ka hopena FBR-FCC. I loko o kā mākou hui, ʻo ka ZSM-5 serial shape-selective zeolites he silica-alumina ratio like ʻole, mai 25 a hiki i 500. Hiki ke hoʻololi ʻia ka puʻupuʻu ʻāpana e like me nā koi o nā mea kūʻai aku. Hiki ke hoʻololi ʻia ka hiki ke isomerization a me ke kūpaʻa hana ke hoʻololi ʻia ka acidity ma ka hoʻololi ʻana i ka ratio silica-alumina e like me kāu mau koi.
