I-Desiccant Dryer Dehydration 4A I-Zeolte Molecular Sieve

Incazelo emfushane:

I-Molecular sieve 4A ifanele ukomiswa kwamagesi (isb: igesi yemvelo, igesi kaphethiloli) noketshezi, enembobo engaba ngu-4 angstroms.

Isimiso sokusebenza sezisefo zamangqamuzana ikakhulukazi sihlobene nosayizi wezimbotshana zezisefo zamangqamuzana, angu-0.3nm/0.4nm/0.5nm ngokulandelana. Bangakwazi ukukhangisa ama-molecule egesi ubukhulu bawo be-molecule buncane kunosayizi we-pore. Ubukhulu bosayizi wembotshana, bukhulu amandla okukhangisa. Ubukhulu bembotshana buhlukile, futhi izinto ezihlungwayo nezihlukaniswayo nazo zihlukile. Ngamagama alula, isisefo se-molecular 3a singakhanga kuphela ama-molecule angaphansi kuka-0.3nm, 4a isisefo samangqamuzana, ama-molecule akhangisiwe nawo kufanele abe ngaphansi kuka-0.4nm, kanye no-5a isisefo se-molecular kuyafana. Uma isetshenziswa njenge-desiccant, isisefo se-molecular singamunca kuze kufike ku-22% wesisindo saso emswanini.

Imininingwane Yomkhiqizo

Omaka bomkhiqizo

Izisefo ze-molecular ze-Zeolite zinesakhiwo se-crystal esivamile esiyingqayizivele, ngasinye sinesakhiwo se-pore sobukhulu obuthile nokuma, futhi sinendawo enkulu ethile. Izisefo eziningi ze-molecular zeolite zinezikhungo ze-asidi eziqinile ngaphezulu, futhi kunenkambu eqinile ye-Coulomb ezimbotsheni zekristalu ze-polarization. Lezi zici ziyenza ibe yi-catalyst enhle kakhulu. Ukusabela kwe-heterogeneous catalytic kwenziwa kuma-catalyst aqinile, futhi umsebenzi we-catalytic uhlobene nosayizi wama-crystal pores we-catalyst. Uma i-zeolite molecular sieve isetshenziswa njenge-catalyst noma umthwali we-catalyst, ukuqhubeka kokusabela kwe-catalytic kulawulwa usayizi we-pore we-zeolite molecular sieve. Usayizi nokuma kwezimbotshana zekristalu nezimbotshana zingadlala indima ekhethiwe ekuphenduleni kwe-catalytic. Ngaphansi kwezimo zokusabela okuvamile, izisefo zamangqamuzana e-zeolite zidlala indima eholayo endleleni yokusabela futhi zibonisa ukusebenza kwe-catalytic okukhetha umumo. Lokhu kusebenza kwenza ama-zeolite ama-molecular sieve abe yinto entsha evuselelayo enamandla aqinile.
