Muri dehydrasi ya Ethanol, amashanyarazi ya zeolite akoreshwa cyane cyane kugirango atsinde aho azeotropique igarukira, kandi akabyara Ethanol ya anhydrous cyangwa etanol yera cyane binyuze mumazi - icyiciro cyangwa gaze - inzira yicyiciro. Iri koranabuhanga rikoreshwa cyane muri bioethanol, ubuvuzi, ibiryo nizindi nganda zikora imiti.
Kuki Ethanol ikeneye kubura amazi?
Mubikorwa byo kubyaza umusaruro, byanze bikunze amazi atangwa mugihe habonetse Ethanol. Ethanol ikora imvange ya azeotropique n'amazi, idashobora kurenga urugero rwa 95,6% mugihe gisanzwe cyo kuyungurura.
Kandi mubikorwa byinganda, Ethanol yera cyane nibisabwa bikenewe. Kubwibyo, umwuma wa Ethanol cyangwa kweza Ethanol urakenewe kugirango ugabanye imipaka ya azeotropique no kubona ibicuruzwa byanyuma binonosoye.
Zeolite Molecular Igikoresho cya Ethanol Dehydration
Ubwoko bwa 3A zeolite ya molekile ya elegitoronike yagaragaye muri dehidrasi ya Ethanol, ikunda cyane ko itanga molekile y'amazi ya polar kandi ikaba idafite na adsorption kuri molekile ya Ethanol, kandi niyo nzira yambere yo kubura umwuma wa Ethanol.
Diameter ya molekile y'amazi igera kuri 2,8 Å, mugihe diameter ya molekile ya Ethanol igera kuri 4.4 Å, bityo micropores (hamwe na diameter ya 3Å) ya 3A zeolite ya molekile ya molekile yemerera molekile zamazi kwinjira mumiyoboro ya adsorption, ariko ikirukana molekile nini ya Ethanol. Kubwibyo, icyuma cya 3A gishobora guhitamo adsorb amazi, amaherezo ikabona Ethanol yera cyane.
Molecular Sieve Ethanol Igikorwa cyo kubura amazi
Gukoresha icyuma cya molekile kugirango ukure amazi kurwego rwa PPM kuri ubu ni bumwe mu buhanga bukuze kandi bunoze mu nganda za Ethanol. Ugereranije nubundi buryo bwo kubura umwuma wa Ethanol, icyuma cya molekile gifite akamaro kanini mubukungu no kubidukikije.
Igikorwa cyo kubura amazi ya TSA: Icyiciro cyamazi Ethanol inyura muburiri bwa adsorption, gushyushya desorption no kuvuka bushya. Irakwiriye kubito n'ibiciriritse - igipimo gikoreshwa, kandi gikunze gukoreshwa muri sisitemu ifite ibikorwa byitsinda hamwe nigihe kirekire cyo gukora.
Gahunda yo kubura umwuma PSA: Icyiciro cya gaz etanol yinjira muri sisitemu ya adsorption mukibazo. Mugihe cyo kwiheba, amazi ararekurwa, agarura amashanyarazi ya molekile. Irakwiriye kuri nini - ingano yinganda zinganda za Ethanol dehydrasiyo ikenera umusaruro uhoraho.
Ibyuma bya molekulari Ibyiza bya Ethanol Dehydration
Ubushobozi bwa tekinoloji: Igice cya molekulari ya dehydrasiyo ifite imbaraga zubworoherane nigiciro gito cyo kwishyiriraho. Amashanyarazi ya molekile biroroshye kubyara, kandi afite ubuzima burebure bwa serivisi, bushobora gutuma umusaruro uhoraho.
Gukora no kubungabunga: Igice cya molekulari ya dehidrasi irashobora gushushanywa hamwe niminara ibiri cyangwa iminara myinshi kugirango bisimburwe kandi bisubirwemo. Iranga kugenzura byikora, imikorere yoroshye no kuyitaho byoroshye.
Isuku no gukora neza: Ubuziranenge bwibicuruzwa byanyuma Ethanol irashobora kugera kuri 99.5% ~ 99.9% (Ethanol anhydrous). Ikoreshwa rya molekile ya sivile dehydrasiya ryabaye igipimo cyinganda zibyara umusaruro wa Ethanol anhydrous, biteza imbere kuzamura icyatsi mubikorwa bya bio na peteroli.
Ubucuti bushingiye ku bukungu no ku bidukikije: Inzira yose nta nyongeramusaruro yangiza, nta gusohora imyanda, ibika ingufu kandi igateza imbere cyane umwuma ugereranije nuburyo gakondo.
