IiPropathi zeKhabhoni esebenzayo
Xa ukhetha ikhabhoni esebenzayo kwisicelo esithile, iimpawu ezahlukeneyo kufuneka ziqwalaselwe:
Ulwakhiwo lwePore
Ubume bepore bekhabhoni evuliweyo buyohluka kwaye ubukhulu becala sisiphumo semathiriyeli yemvelaphi kunye nendlela yokuvelisa.¹ Ubume bepore, ngokudityaniswa namandla anomtsalane, yiyo evumela ukuba i-adsorption yenzeke.
Ukuqina/Ukuqhawuka
Ukuqina / ukukrazula kwakhona yinto ephambili ekukhetheni. Izicelo ezininzi ziya kufuna ukuba ikhabhoni esebenzayo ibe namandla amasuntswana aphezulu kunye nokuchasana nokunciphisa (ukuqhekeka kwezinto zibe ziintlawulo). Ikhabhoni esebenzayo eveliswe kumaqokobhe ekhokhonathi inowona bunzima buphezulu beekhabhoni ezisebenzayo.
Iipropati ze-Adsorptive
Iipropathi zokufunxa zekhabhoni esebenzayo ziquka iimpawu ezininzi, kubandakanywa amandla e-adsorptive, izinga le-adsorption, kunye nokusebenza ngokubanzi kwekhabhoni esebenzayo.
Ngokuxhomekeke kwisicelo (ulwelo okanye irhasi), ezi mpawu zinokubonakaliswa ngenani lezinto, kubandakanywa inombolo ye-iodine, indawo ephezulu, kunye nomsebenzi weCarbon Tetrachloride (CTC).
Uxinzelelo olubonakalayo
Nangona uxinaniso olubonakalayo aluyi kuchaphazela i-adsorption nganye yeyunithi ubunzima, kuya kuchaphazela i-adsorption yeyunithi nganye.
Ukufuma
Ngokufanelekileyo, ubuninzi bomzimba obumanzi obuqulethwe kwikhabhoni esebenzayo kufuneka buwele ngaphakathi kwe-3-6%.
Isiqulatho sothuthu
Umxholo womlotha wekhabhoni esebenzayo ngumlinganiselo we-inert, i-amorphous, i-inorganic, kunye nenxalenye engasebenzisekiyo yezinto. Isiqulatho sothuthu siya kuba sisezantsi kangangoko, njengoko umgangatho wekhabhoni esebenzayo ukhula njengoko umxholo wothuthu uyancipha.
Ixabiso le-pH
Ixabiso le-pH lidla ngokulinganiswa ukuqikelela utshintsho olunokubakho xa ikhabhoni esebenzayo yongezwa kulwelo.
Ubungakanani beNcam
Ubungakanani be-particle bunefuthe elithe ngqo kwi-adsorption kinetics, iimpawu zokuhamba, kunye nokuhluzwa kwekhabhoni esebenzayo.
Imveliso yeCarbon esebenzayo
Ikhabhoni esebenzayo iveliswa ngeenkqubo ezimbini eziphambili: i-carbonization kunye nokusebenza.
Ukwenziwa kweCarbonization
Ngexesha le-carbonization, imathiriyeli ekrwada iboliswa ngokufudumeleyo kwindawo engasebenziyo, kumaqondo obushushu angaphantsi kwama-800 ºC. Ngokufakwa kwegesi, izinto ezinje ngeoksijini, ihydrogen, initrogen, kunye nesalfure, ziyasuswa kwisixhobo somthombo.
Ukuqaliswa
I-carbonized material, okanye i-char, kufuneka isebenze ngoku ukuphuhlisa ngokupheleleyo ubume bepore. Oku kwenziwa ngokufaka i-oxidizing i-char kumaqondo obushushu aphakathi kwe-800-900 ºC kubukho bomoya, i-carbon dioxide, okanye umphunga.
Ngokuxhomekeke kwimithombo yomthombo, inkqubo yokuvelisa i-carbon activated ingenziwa ngokusebenzisa i-activation ye-thermal (physical / steam), okanye ukusetyenziswa kweekhemikhali. Kuyo nayiphi na imeko, i-rotary kiln ingasetyenziselwa ukucubungula izinto kwikhabhoni esebenzayo.
