Ha 4a sieve ea molek'hule e sa phuthetsoe ka thata kapa tikoloho ea polokelo e senyehile, mokhoa oa ho sebetsana le ho monya metsi le mongobo oa eona?Kajeno re tla qaqisa matla a adsorption ea sieve ea limolek'hule le mekhoa ea kalafo ea ho monya metsi le hygroscopicity.
Sieve ea molek'hule e na le matla a matla a adsorption.E ke ke ea monya metsi feela, empa hape e monya litšila tse moeeng.Ka hona, tlhahisong ea indasteri, hangata e sebelisoa bakeng sa ts'ebetso ea adsorption, ka hona e bapala karolo e ntle ea karohano le papatso.Re lokela ho etsa eng haeba 4a molecular sieve e bolokoa ka tsela e fosahetseng kapa e kolobisitsoe haholo nakong ea tšebeliso?
1. Koalavalve ea ho kena ka tora e ka sehloohong, fetola feela li-sieve tsa limolek'hule tsa litanka tse peli bakeng sa adsorption, 'me u sebelise moea o ka morao ho li-molecular sieves ntle le metsi ho tsosolosa li-sieve tsa molek'hule.Leha ho le joalo, ha lifefo tsa limolek’hule tse se nang metsi li fetoloa hore li sebetse, metsi a ka mor’a tsona a tla kena ka har’a sefene sa molek’hule ntle le metsi.Li-sieve tsena tse peli tsa molek'hule ka bobeli li na le metsi, ebe li nchafatsana.Ka ho tsosolosoa ha adsorption, metsi a fokotseha, 'me qetellong a fihlella ka nako e le' ngoe adsorption.
2.Ka ho tobaho futhumatsa le ho omisa 4a sieve ea molek'hule ho e ntša metsi kapele kamoo ho ka khonehang le ho tsosolosa matla a eona a adsorption;Leha ho le joalo, ka mor'a hore metsi a mangata a kene ka har'a sieve ea limolek'hule, ha ho sebelisoa mokhoa o ka holimo ho tsosolosa, li-sieve tse peli tsa molek'hule li tla hlahisa metsi a mangata, ka bobeli li tla tsosolosa 'me qetellong li lahleheloe ke matla a tsona a adsorption.Lebaka ke: ka mor'a hore metsi a mangata a kene ka zeolite, metsi a itšoara ka zeolite, 'me metsi a fetoha ho tloha sebakeng sa mahala ho ea ho metsi a kristale a zeolite.Esita le haeba mocheso oa ho tsosolosoa o le likhato tse 200, metsi a kristale a ke ke a tlosoa, 'me mosebetsi oa adsorption oa zeolite o ka tsosolosoa feela ka mor'a hore o khutlisetsoe sebōping ka likhato tse 400 ke moetsi!
Ka hona, ha sieve ea molek'hule e monya metsi sebakeng se seholo 'me e ameha ka mongobo, ts'ebetso e tla emisoa hang-hang' me ho tsosolosoa ho tla etsoa.Haeba adsorption e ke ke ea khutlisoa ka mekhoa e 'meli e kaholimo, ho tla ikopanya le moetsi kapele kamoo ho ka khonehang ho lokisa calcination.
4a Ts'ebetso ea sieve ea molek'hule le mokhoa oa ho nchafatsa:
1. 4a Phetoho ea mocheso oa zeolite, e leng "mocheso o fetohang"
The adsorbate e tlosoa ka ho futhumatsa molek'hule sieve.Ka kakaretso, li-sieve tsa limolek'hule tse sebelisoang indastering li futhumatsoa pele 'me li futhumatsoa hape, li hloekisoa ho fihla ho 200 ℃, 'me adsorbed e senyehileng ea ntšoa.
2. Fetola khatello e lekanyelitsoeng ea 4a zeolite
