Monyetla oa metsi oa sieve ea molek'hule o ipapisitse le boleng ba metsi a sehlahisoa, 4A litataiso tsa ho tlosoa ha metsi ka molek'hule.
1. Tšebeliso: 4A sieve ea molek'hule e na le matla a ho khetha adsorption 'me e ka tlosa mongobo ho li-solvents le likhase tse phelang, empa ha e khahlise li-solvents le likhase (tse kang tetrahydrofuran).Mokhoa oa pele o amohela caustic soda dehydration, caustic soda e qhibilihang ka metsing, ha ho bonolo ho arohana le tetrahydrofuran ka mor'a ho felloa ke metsi, e sebelisa soda ea caustic ho ba thata bakeng sa ho tsosolosa, e hlile e eketsehile litšenyehelo.
2. Mokhoa oa ts'ebetso: Ts'ebetso ea dehydration ea 4A molecular sieve e batla e le bonolo.Sieve ea molek'hule e ka kenngoa ka ho toba ho tlosoa ha solvent, kapa tharollo le khase li ka fetisoa ka ho toba ka molecular sieve adsorption tower.
3. Matla a Adsorption: Sieve ea molek'hule 4A e na le bokhoni bo batlang bo le boholo ba adsorption, ka kakaretso 22%.
4. Khetho ea ts'ebetso ea adsorption: 4A sieve ea molek'hule e ka monya limolek'hule tsa metsi habonolo.Hobane bophara ba limolek'hule tsa metsi bo nyane ho feta ba zeolite, ho leka-lekana ha electrostatic ho ka finyelloa ka mor'a adsorption (li-molecular sieves ha li monye likaroloana tse nang le li-diameter tse kholo ho feta tsa li-molecular sieves).
5.Analysis ntle le ho hlahisa metsi: 4a sieve ea molek'hule e ke ke ea lokolloa ka mor'a ho monya metsi mocheso oa kamore.
6. Ho tsosolosoa: Ho tsosolosoa ha 4A molecular sieve ho batla ho le bonolo.Ka mor'a hora, naetrojene e ka holimo ho 300 ° C e ka sebelisoa hape (lintho tse sa cheng li ka pompeloa moeeng ka ho toba).
7. Bophelo ba nako e telele ea tšebeletso: 4A sieve ea molek'hule e ka tsosolosoa ka lilemo tse 3-4.
Li-sieve tsa limolek'hule li na le hygroscopicity e matla ho mongobo, kahoo li lokela ho sebelisoa bakeng sa tlhoekiso ea khase 'me li lokela ho qoba ho kopana ka ho toba le moea.Li-sieve tsa limolek'hule tse monyelitseng mongobo li lokela ho tsosolosoa ka mor'a hore li bolokoe nako e telele.Li-sieve tsa molek'hule li qoba oli le metsi a metsi.Leka ho qoba ho kopana le oli le metsi a metsi nakong ea tšebeliso.Likhase bakeng sa ho omisa kalafo lihlahisoa tsa indasteri li kenyelletsa moea, hydrogen, argon, joalo-joalo.E le ho lumella ts'ebetso e tsoelang pele ea lisebelisoa, li fapanyetsana.Se omisitsoeng se sebetsa mochesong o tloaelehileng, 'me se etsa nchafatso ea ho hlatsoa moea ka mocheso o ka holimo ho 340°C.
Mokhoa le molao-motheo oa ho felloa ke metsi ka molek'hule
Ho felloa ke metsi 'meleng ke mokhoa oa adsorption oa' mele.Ho ata ha khase haholo ho bakoa ke matla a khoheli a Fan kapa matla a pharalletseng.The adsorption ea khase e tšoana le condensation ea khase.Ka kakaretso ha e khethe 'me ke mokhoa o ka khutlisoang morao.Mocheso oa adsorption o monyenyane 'me matla a ts'ebetso a hlokahalang bakeng sa adsorption a nyenyane, kahoo lebelo la adsorption Ka potlako, ho bonolo ho finyella ho leka-lekana.
