Makhalidwe a ma adsorbents osiyanasiyana
Mpweya wopangidwa:Ili ndi kapangidwe kake kakang'ono kwambiri kamene kali ndi mapokoso ndi masoposo, komwe kali ndi malo akeake a 500-1000m2/g, ndipo kukula kwa mapokoso kumasiyana pakati pa 2-50nm. Kaboni woyatsidwa umadalira kwambiri mphamvu ya van der Waals yomwe imapangidwa ndi adsorbate kuti ipange adsorption, ndipo imagwiritsidwa ntchito makamaka poyamwa ndi kuchotsa mankhwala achilengedwe, mankhwala olemera a hydrocarbon organic, ndi ma deodorants;
Sefa ya maselo:Ili ndi kapangidwe kabwino ka ma pore okhala ndi ma microporous okhala ndi malo enaake a pamwamba pa 500-1000m2/g, makamaka opangidwa ndi ma micropore, okhala ndi kukula kwa ma pore pakati pa 0.4-1nm. Makhalidwe a adsorption a ma molecular seeves amatha kusinthidwa posintha kapangidwe kawo, kapangidwe kake, ndi mtundu wa equilibrium cations. Ma molecular seeves amadalira kwambiri kapangidwe ka ma pore ndi mphamvu ya Coulomb pakati pa equilibrium cations ndi ma molecular seefer framework kuti apange adsorption. Ali ndi kukhazikika kwabwino kwa kutentha ndi hydrothermal ndipo amagwiritsidwa ntchito kwambiri pakulekanitsa ndi kuyeretsa magawo osiyanasiyana a mpweya ndi madzi. Akagwiritsidwa ntchito ngati adsorbents, ma molecular seeves amakhala ndi kusankha kwamphamvu, kuzama kwakukulu kwa adsorption, komanso mphamvu yayikulu ya adsorption;
Silika gel:Chokometsera cha mtundu wa silicone chili ndi malo akeake a pamwamba pa 300-500m2/g, makamaka mesoporous, ndi kukula kwa ma pore a 2-50nm. Pamwamba pa ma pore channels ake muli magulu ambiri a hydroxyl pamwamba, omwe amagwiritsidwa ntchito makamaka powumitsa ma adsorption ndi pressure swing adsorption kuti apange CO2;
Aluminiyamu yogwiritsidwa ntchito:Ndi malo akeake a 200-500m2/g, nthawi zambiri imakhala yopapatiza ndipo imafalikira ndi kukula kwa ma pore a 2-50nm. Imagwiritsidwa ntchito makamaka poumitsa, kutaya madzi m'thupi, kuyeretsa mpweya woipa, ndi zina zotero.
