ZSM-5 uhlobo zeolite, okuqondene ephezulu Silica zeolite nokuba Si / Al ratio abafika kwabangu-1000 nangaphezulu, futhi ubonisa izici hydrophobic. Isici nesakhiwo zeolite enjalo ukuthi izingxenye mpo futhi enezingqimba kukhona crystalline alum inosilicate sakhiwa isiteshi 10-membered. Isakhiwo esiyisisekelo yakhiwa eziyisishiyagalombili izindandatho 5-membered, okuyinto ineziteshi kuphela futhi ngaphandle izimbotshana yezinyoni-DRM. ZSM-5 has amasede amabili iziteshi cross, enye yazo lesiyingi, futhi ububanzi iwindi thereof is 0.55 ukuze 0.60nm. Njengoba isikhala ukuphendula iyafana ukuma ukufinyelela, lo zeolite kunomphumela Ukukhetha ukuma kuya reactants kanye nemikhiqizo. Ngaphezu kwalokho, ZSM-5 sisetshenziselwa izinto ezinhle ebomvu kulethe abakhethayo ngenxa ivumelane isakhiwo kanye ezingaphansi kolwandle ukuzinza.
ZSM-5 uhlobo zeolite is kabanzi isetshenziswa Petrochemical ukucutshungulwa izimboni, isetshenziswa fluidifying, catalyzing nokucubungula ngokuhlaziya njengoba umsizi ngokukhiqiza propylene owengeziwe negesi kuncibilike, kanye nokwenza ngcono isibalo octane we uphethiloli. Ngaphezu kwalokho, zeolite singasetshenziswa ekukhiqizeni ethylbenzene, xylene, phenol, pyridine, njll
Isicelo:
1.ZSM - 5 ngesihlungo yamangqamuzana esetshenziselwa FCC kulethe: ezivamile SiO2 / Al2O3 isilinganiso esiphakathi 40 ukufika e-50
2.ZSM - 5 ngesihlungo yamangqamuzana esetshenziselwa FCC uphethiloli izithasiselo ukunciphisa olefin: ezivamile SiO2 / Al2O3 isilinganiso esiphakathi 38 40
3.ZSM - 5 ngesihlungo yamangqamuzana esetshenziselwa resid kwemifantu okhanda amanye amathuba: ezivamile SiO2 / Al2O3 isilinganiso esiphakathi 25 kuya 30.
4.ZSM - 5 sieves yamangqamuzana umkhakha zamakhemikhali, chemical esihle umkhakha kabanzi catalysis ukuma-abakhethayo, ezifana diethylbenzene kulethe, xylene kulethe isomerization, ETHYL acetate, ethylene glycol, ethylene glycol butyl ether ka kulethe has anhlobonhlobo ukusetshenziswa.
