ZSM-5 momo zeolite, no tiketike-takawai zeolite me te he i te ōwehenga Si / Al o runga ki te 1000, me te i runga, whakaatu hoki te āhuatanga hydrophobic. Ko te āhuatanga hanganga o te zeolite taua ko e te wahi poutū me te whakapae he inosilicate waikonumohe, tioata tito o teihana 10-membered. tito te hanganga taketake te o waru mowhiti 5-membered, e kua anake takere me he kahore kōwhao whare herehere-free. He ZSM-5 rua huinga o takere ripeka, tetahi o i te tītaha, a ona te diameter matapihi ko te 0.55 ki te 0.60nm. Ka rite ki te mea rite ki te āhua o te whai wāhi te wāhi tauhohe, te zeolite he pānga āhua kōwhiringa ki te matū hohe me ngā hua. Ano, ZSM-5 Ko te rauemi raw pai o te whakakōkī whiriwhiri tika ki te pai te hanganga me te parawhenuatia pūmautanga.
Kei te whānui ZSM-5 momo zeolite tono ki ngā ahumahi tukatuka matūngahinu, tono ki te fluidifying, catalyzing me te hangai tukanga hei kaiāwhina mō te whakaputa atu propylene me hau liquefied, me te whakapai ake i te tokomaha wāwaro o te penehīni. I tua atu, e taea te tono i te zeolite ki te hanga o te ethylbenzene, xylene, phenol, pyridine, me ētahi atu
Taupānga:
1.ZSM - 5 tatari rāpoi whakamahia mō te fcc whakakōkī: tikanga ōwehenga SiO2 / Al2O3 he i waenganui i 40 ki te 50.
2.ZSM - 5 tatari rāpoi whakamahia mō te tāpiritanga penehīni fcc ki te whakaiti i te olefin: tikanga ōwehenga SiO2 / Al2O3 ko waenganui i 38 ki te 40.
3.ZSM - 5 tatari rāpoi whakamahia mō te papatanga catalytic resid: tikanga ōwehenga SiO2 / Al2O3 he i waenganui i te 25 ki te 30.
4.ZSM - 5 sieves rāpoi i roto i te ahumahi matū, kei te whānui whakamahia ahumahi matū pai i roto i te catalysis āhua-whiriwhiri, pērā i diethylbenzene whakakōkī, xylene whakakōkī isomerization, Ethyl tāpia, ethylene glycol, ethylene glycol butyl Etera o whakakōkī he whānui o whakamahinga ngā.
