Zvivakwa zveActivated Carbon
Paunenge uchisarudza iyo activated kabhoni yeimwe application, akasiyana siyana maitiro anofanirwa kutariswa:
Pore Structure
Mamiriro epore eakabatidzwa kabhoni anosiyana uye zvinonyanya kukonzerwa nekwakabva zvinhu uye nzira yekugadzira.¹ Maumbirwo epore, pamwe chete nemasimba anoyevedza, ndiwo anotendera kuti adsorption iitike.
Kuoma/kubvongodzwa
Kuomarara/abrasion zvakare chinhu chakakosha pakusarudza. Mazhinji maapplication anozoda iyo activated kabhoni kuti ive yakakwira particle simba uye kuramba kune attrition (kuparara kwezvinhu kuita faindi). Activated carbon inogadzirwa kubva kukokonati shells ine yakanyanya kuoma kwemakabhoni akagadzirwa.
Adsorptive Properties
Iwo absorptive zvimiro zveiyo activated kabhoni inotenderedza akati wandei maitiro, anosanganisira adsorptive kugona, mwero weadsorption, uye kushanda kwese kweiyo activated kabhoni.
Zvichienderana nekushandiswa (mvura kana gasi), zvivakwa izvi zvinogona kuratidzwa nezvakati wandei, zvinosanganisira nhamba yeiodine, nzvimbo, uye Carbon Tetrachloride Activity (CTC).
Apparent Density
Nepo density inooneka isingakanganise adsorption pahuremu hweyuniti, inokanganisa adsorption pavhoriyamu yeyuniti.
Unyoro
Sezvineiwo, huwandu hwehunyoro hwemuviri huri mukati meiyo activated kabhoni hunofanirwa kuwira mukati me3-6%.
Ash Content
Iyo ash yemukati yeakabatidzwa kabhoni chiyero cheinert, amorphous, inorganic, uye isinga shandiswe chikamu chechinhu. Madota emukati anozove akadzikira sezvinobvira, sezvo kunaka kweiyo activated kabhoni kunowedzera sezvo madota anodzikira.
pH Kukosha
Iyo pH kukosha inowanzoyerwa kufanotaura ingangoita shanduko kana activated kabhoni yawedzerwa kumvura.
Particle Size
Particle saizi ine yakananga mhedzisiro pane adsorption kinetics, kuyerera maitiro, uye kusefa kweiyo activated kabhoni.
Activated Carbon Production
Activated carbon inogadzirwa kuburikidza nemaitiro maviri makuru: carbonization uye activation.
Carbonization
Munguva yecarbonization, iyo mbishi inosvibiswa nekushisa munzvimbo inert, patembiricha iri pasi pe800 ºC. Kuburikidza negasification, zvinhu zvakaita seokisijeni, hydrogen, nitrogen, uye sulfuri, zvinobviswa kubva kune iyo sosi zvinhu.
Activation
Iyo carbonized material, kana char, inofanira ikozvino kushandiswa kuti inyatso gadzira pore chimiro. Izvi zvinoitwa kuburikidza nekuita oxidizing char patembiricha iri pakati pe800-900 ºC pamberi pemhepo, carbon dioxide, kana chiutsi.
Zvichienderana nekwakabva zvinhu, maitiro ekugadzira activated kabhoni anogona kuitwa uchishandisa chero thermal (yemuviri / mhepo) activation, kana kemikari activation. Chero zvazvingaitika, kini inotenderera inogona kushandiswa kugadzira zvinhu kuita kabhoni yakabatidzwa.
