Izici ze-adsorbents ezahlukene
Ikhabhoni esebenzayo:Inesakhiwo esicebile esinezimbobo ezincane nezincane, esinendawo ethile engaphezulu engaba ngu-500-1000m2/g, kanye nokusatshalaliswa kosayizi wembobo ikakhulukazi phakathi kuka-2-50nm. Ikhabhoni esebenzayo incike kakhulu emandleni e-van der Waals akhiqizwa yi-adsorbate ukuze ikhiqize i-adsorption, futhi isetshenziselwa kakhulu i-adsorption kanye nokususwa kwamakhemikhali e-organic, amakhemikhali e-hydrocarbon esindayo e-organic, kanye nama-deodorant;
Isihlungi sama-molecule:Inesakhiwo sembobo ezincane ezivamile esinendawo ethile engaphezulu engaba ngu-500-1000m2/g, ikakhulukazi esakhiwe ngama-micropores, kanye nokusatshalaliswa kosayizi wembobo phakathi kuka-0.4-1nm. Izici zokufakwa kwe-adsorption kwama-molecule sieves zingashintshwa ngokulungisa isakhiwo sazo, ukwakheka, kanye nohlobo lwama-equilibrium cations. Ama-molecule sieves athembele kakhulu esakhiweni sembobo esiyingqayizivele kanye nensimu yamandla e-Coulomb phakathi kwama-equilibrium cations kanye nohlaka lwesivimbo se-molecular ukuze kukhiqizwe i-adsorption. Anezimo ezinhle zokushisa kanye ne-hydrothermal futhi asetshenziswa kabanzi ekuhlukaniseni nasekuhlanzeni izigaba ezahlukene zegesi kanye noketshezi. Uma zisetshenziswa njenge-adsorbents, ama-molecule sieves anokukhetha okunamandla, ukujula okuphezulu kwe-adsorption, kanye namandla amakhulu e-adsorption;
Ijeli ye-silica:I-adsorbent yohlobo lwe-silicone inendawo ethile engaphezulu engaba ngu-300-500m2/g, ikakhulukazi e-mesoporous, enokusatshalaliswa kosayizi we-pore ongu-2-50nm. Ubuso bangaphakathi beziteshi zayo ze-pore buqukethe amaqembu amaningi e-hydroxyl ebusweni, asetshenziselwa kakhulu ukomisa i-adsorption kanye ne-pressure swing adsorption ukukhiqiza i-CO2;
I-alumina esebenzayo:Njengoba inendawo ethile yobuso engu-200-500m2/g, ivame ukuba yi-mesoporous futhi inobukhulu be-pore obungu-2-50nm. Isetshenziswa kakhulu ukomisa, ukuphelelwa amanzi emzimbeni, ukuhlanzwa kwegesi engcolile ene-acidic, njll.
