Ukuhlaziywa kwamanzi adsorption
I-adsorption yamanzi ingahlukaniswa ibe i-static water adsorption kanye ne-dynamic adsorption yamanzi.Amanzi amile adsorption,kusho ukuthi ngaphansi kwesimo izinga lokushisa elithile kanye nomswakama othile, ngemva kokufinyelela ukulingana okuguquguqukayo, okuqukethwe kwamanzi adsorbed we-adsorbent, ukuthi ekusebenzeni komshini kuyindaba yezimo zokusebenza eziqhubekayo,idatha ye-static adsorption iphezulu kakhulu,indawo yamazolo yokusebenza kwegesi ethunyelwa ngaphandle kuzoba ngcono.
Ukukhangisa kwamanzi anamandla kubhekisela enanini le-adsorbent lamanzi adsorbed ekugelezeni komoya ekungeneni kombhede, okungukuthi, lapho kufakwa amanzi ekugelezeni komoya, isisindo esingeziwe ngemva kokufinyelela endaweni eshiwo yamazolo.Ngenxa yezimo ezahlukene zokusebenza namamodeli, iphuzu lamazolo likhonafuthi ezahlukene.Kodwa kuyafana nokusetshenziswa kwamanzi amile,kokubiliof amanzi adsorption iphakeme kakhulu, kuba ngcono ukusebenza kwe-adsorption yomkhiqizo.
Ukuhlaziywa kwendawo engaphezulu
Indawo engaphezulu ngeyunithi ngayinye yesisindo, ehlobene nokusebenza kwe-adsorption.Uma indawo ethile engaphezulu ibe nkulu, iba nkulu indawo yokuthintana okucatshangelwayo ngokugeleza komoya, ukuze isivinini se-adsorption sisheshe futhi i-adsorption ibe namandla.
In iisicelookomisa umoya, phezuluindawokwe-adsorbentkuphakeme kakhulu,, indawo ethintana nayo ngokugeleza komoya iba nkulu futhi iyancipha indawo yamazolo.Ngokuvamile, kukho konke ukukhuphuka okungu-100m2/g endaweni ethile, izinga le-adsorption likhuphuka ngo-5-10% endaweni ehlobene ye-RH60%.
Ukuhlaziywa kwevolumu ye-Pore
Uma ubheka ngaphansi kwesibonakhulu, uzothola ukuthi i-alumina ecushiwe inama-micro-pores amaningi, okungenye yezimpawu ezibalulekile ze-adsorbent enezimbobo noma i-catalyst.Umthamo we-micro-pore ku-adsorbent ubizwa ngokuthi umthamo we-pore, okuyinani elitholakala kuvolumu ye-saturation adsorption, okungukuthi, ingakanani ivolumu ye-adsorbent engakwazi ukubamba i-adsorbent, ngakho-ke ubukhulu bembobo, bungcono.Isidingo sevolumu yembotshana ye-alumina evuliwe sikhulu noma silingana no-0. 35 cm³/g kuzinga lomugqa.
