Uhlalutyo lwe-adsorption yamanzi
I-adsorption yamanzi inokwahlulwa ibe yi-static water adsorption kunye ne-dynamic adsorption yamanzi.Amanzi amileyo adsorption,kuthetha ukuba phantsi kwemeko yobushushu obuthile kunye nokufuma okusingqongileyo, emva kokufikelela kwi-equilibrium eguquguqukayo, umxholo wamanzi we-adsorbent, ukuba ekusebenzeni komatshini yimeko yokusebenza rhoqo,idatha ye-static adsorption yamanzi iphezulu kakhulu,indawo yombethe yokusebenza kwerhasi kumazwe angaphandle kuya kuba ngcono.
I-Dynamic adsorption yamanzi ibhekiselele kwisixa se-adsorbent ye-adsorbed yamanzi e-adsorbed kwi-airflow ukuya ekungeneni kwebhedi, oko kukuthi, xa amanzi e-adsorbing ekuphumeni komoya, ubunzima bongeziweyo emva kokufikelela kwindawo yombethe echaziweyo.Ngenxa yeemeko ezahlukeneyo zokusebenza kunye neemodeli, indawo yombethekwakhona ezahlukeneyo.Kodwa into efanayo ne-static adsorption yamanzi,zombiniof ukubhengezwa kwamanzi ingaphezulu, ngcono ukusebenza kwe-adsorption yemveliso.
Uhlalutyo lwendawo engaphezulu
Indawo engaphezulu ngeyunithi yobunzima bezinto eziphathekayo, ehambelana nokusebenza kwe-adsorption.Ubukhulu bendawo ethile yomphezulu, inkulu indawo yokunxibelelana nethiyori kunye nokuhamba komoya, ukuze isantya se-adsorption sikhawuleze kwaye i-adsorption yomelele.
In iisiceloesomisi moya, umphezuluindawokwi-adsorbentiphezulu kakhulu,, kokukhona usiba mkhulu umphezulu wokudibana kunye nokuhamba komoya kunye nokusezantsi indawo yombethe.Ngokuqhelekileyo, ngokunyuka kwe-100m2 / g kwindawo ethile, izinga le-adsorption liyenyuka nge-5-10% kwi-RH60% yendawo ehambelanayo.
Uhlalutyo lomthamo wePore
Ukuba ujonga phantsi kwe-microscope, uya kufumanisa ukuba i-alumina evuliwe inemibhobho emincinci emininzi, enye yeempawu ezibalulekileyo zeempawu ze-adsorbent edibeneyo okanye i-catalyst.Umthamo we-micro-pore kwi-adsorbent ubizwa ngokuba yi-pore umthamo, ixabiso elivela kumthamo we-saturation adsorption, oko kukuthi, ungakanani umthamo we-adsorbent onokubamba i-adsorbent, ngoko ke ubukhulu bepore, bungcono.Imfuno yomthamo wepore yealumina evuliweyo inkulu kuno okanye ilingana no-0. 35 cm³/g kumgangatho womgca.
