Alcohol Dehydration in Distillation Tower/Desiccant/Adsorbent/Hollow glass molecular sieve

Tlhaloso e Khutšoanyane:

Molecular sieve 3A, eo hape e tsejoang e le molecular sieve KA, e nang le lesoba le ka bang 3 angstroms, e ka sebelisoa bakeng sa ho omisa likhase le maro hammoho le ho felloa ke metsi a hydrocarbon. E boetse e sebelisoa haholo bakeng sa ho omisa peterole ka botlalo, likhase tse phatlohileng, ethylene, propylene le likhase tsa tlhaho.

Molao-motheo oa ts'ebetso oa li-sieve tsa limolek'hule o amana haholo le boholo ba pore ea sieve ea molek'hule, e leng 0.3nm/0.4nm/0.5nm ka ho latellana. Ba ka adsorb limolek'hule tsa khase tseo bophara ba tsona ba molek'hule bo leng nyane ho feta boholo ba pore. Ha boholo ba boholo ba pore bo boholo, matla a adsorption a maholo. Boholo ba pore bo fapane, 'me lintho tse sefiloeng le tse arohaneng le tsona li fapane. Ka mantsoe a bonolo, 3a sieve ea limolek'hule e ka bapa limolek'hule tse ka tlase ho 0.3nm, 4a sieve ea molek'hule, limolek'hule tse batiloeng le tsona li tlameha ho ba ka tlase ho 0.4nm, 'me 5a sieve ea molek'hule e tšoana. Ha e sebelisoa e le desiccant, sieve ea molek'hule e ka monya ho fihlela ho 22% ea boima ba eona ka mongobo.

Li-sieve tsa molek'hule tsa Zeolite li na le sebopeho se ikhethileng sa kristale se tloaelehileng, se seng le se seng se na le sebopeho sa pore sa boholo bo itseng le sebopeho, 'me se na le sebaka se seholo se khethehileng. Li-sieve tse ngata tsa limolek'hule tsa zeolite li na le litsi tse matla tsa acid ka holim'a metsi, 'me ho na le tšimo e matla ea Coulomb ka har'a li-crystal pores bakeng sa polarization. Litšobotsi tsena li etsa hore e be mokelikeli o babatsehang. Karabelo e fapaneng ea catalytic e etsoa ho li-catalysts tse tiileng, mme ts'ebetso ea catalytic e amana le boholo ba li-pores tsa kristale tsa catalyst. Ha sieve ea molek'hule ea zeolite e sebelisoa e le mokelikeli kapa mochine oa li-catalyst, tsoelo-pele ea karabelo ea catalytic e laoloa ke boholo ba pore ea zeolite molecular sieve. Boholo le sebopeho sa li-pores tsa kristale le li-pores li ka bapala karolo e ikhethileng ts'ebetsong ea catalytic. Tlas'a maemo a karabelo e akaretsang, li-sieve tsa limolek'hule tsa zeolite li bapala karolo e etelletseng pele tseleng ea karabelo mme li bonts'a ts'ebetso e ikhethileng ea sebopeho. Ts'ebetso ena e etsa hore li-sieve tsa limolek'hule tsa zeolite e be lisebelisoa tse ncha tse matlafatsang tse nang le matla a matla.
