uchi zeolite molecular sieve

Mafotokozedwe Akatundu:

Chinthu chachikulu cha uchi zeolite ndi zeolite zachilengedwe, zomwe ndi inorganic microporous material yopangidwa ndi SiO2, Al2O3 ndi zitsulo zamchere kapena zamchere zamchere zamchere. Voliyumu yake yamkati ya pore imakhala ndi 40-50% ya voliyumu yonse ndipo malo ake enieni ndi 300-1000 m2 / g. Lili ndi zizindikiro za kukana kutentha kwapamwamba, kusatentha, kutentha kwabwino komanso kukhazikika kwa hydrothermal. Ndi chonyamulira cha sieve champhamvu kwambiri chokhala ndi ntchito yabwino yotsatsa, palibe kuipitsidwa kwachiwiri, ndipo imatha kupangidwanso pakutentha kwambiri. Poyerekeza ndi zisa za carbon activated, ntchito yake ndi pafupifupi 25%. High dzuwa, chimagwiritsidwa ntchito adsorption, kulekana, catalysis ndi minda zachilengedwe, oyenera voliyumu yaikulu mpweya, otsika ndende organic zinyalala mankhwala.

Mawonekedwe:

1. Kusankha kwamphamvu kwa ma adsorption: Sieve ya molekyulu imakhala ndi pore yowoneka bwino komanso yofananira ndipo ndi ionic adsorbent. Choncho, akhoza kusankha adsorb malinga ndi kukula ndi polarity wa mamolekyu, ndi bwino kuchotsa ethylene ndi propylene ku zimalimbikitsa hydrocarbons. Kuchotsedwa kwa acetylene ku ethylene kumatsimikiziridwa ndi polarity yake yolimba.

2. Mphamvu yamphamvu ya adsorption: Ngakhale kuchuluka kwa gasi kumakhala kochepa kwambiri, kumakhalabe ndi mphamvu zotsatsa.

3. Simakhudzidwa kwambiri ndi kutentha ndipo imakhalabe ndi mphamvu zowonjezera zowonjezera kutentha, pamene ma adsorbents ena amakhudzidwa kwambiri ndi kutentha.

Zisa za uchi zeolite molecular sieves ndi: microporous molecular sieves ndi mesoporous molecular sieves.

(1) Masefa ang'onoang'ono a molekyulu okhala ndi pore ya molekyulu yochepera 2nm ndi 2-50nm ndi masoporous molecular sieves (pamwamba pa 50nm ndi macroporous molecular sieves). Masefa a Mesoporous molecular ali ndi malo apamwamba kwambiri, mawonekedwe okhazikika komanso olongosoka, kagayidwe kakang'ono ka pore, ndi kukula kwa pore. Makhalidwe a kukula kosinthika kosalekeza kumapangitsa kuti zikhale zovuta kutsatsa ndikulekanitsa ma macromolecules m'masefa ambiri a microporous molecular. ndi kutenga gawo lofunikira pakuchitapo kanthu.

(2) Posankha, ma molekyulu a sieve okhala ndi katundu wosiyanasiyana ndi kukula kwa pore ayenera kukhazikitsidwa molingana ndi magawo osiyanasiyana a gasi wa zinyalala kuti akwaniritse chithandizo cha gasi wa zinyalala, kukwaniritsa zofunikira, ndikukwaniritsa miyezo yotulutsa mpweya.

Kukula kwachisa kwa zeolite molecular sieve ndi 100 * 100 * 100mm. Timaperekanso ntchito zosinthidwa makonda. Posachedwapa, kasitomala anagula 168 * 168 * 100mm uchi zeolite molecular sieve kwa ife.
