Katundu wa Activated Carbon
Posankha kaboni woyamwa kuti agwiritse ntchito, mitundu yosiyanasiyana iyenera kuganiziridwa:
Kapangidwe ka Pore
Kapangidwe ka mbombo ka carbon activated zimasiyanasiyana ndipo makamaka chifukwa cha gwero ndi njira yopangira.¹ Kapangidwe ka bore, kuphatikiza ndi mphamvu zokopa, ndizomwe zimalola kuti kudsorption kuchitike.
Kuuma / Kutupa
Kuuma / kuyabwa ndi chinthu chofunikira pakusankha. Ntchito zambiri zimafuna kuti mpweya woyamwa ukhale ndi mphamvu ya tinthu tambirimbiri komanso kukana kutsika (kuwonongeka kwa zinthu kukhala chindapusa). Mpweya wopangidwa kuchokera ku zipolopolo za kokonati uli ndi kuuma kwambiri kwa carbon activated.
Ma Adsorptive Properties
Mayamwidwe a carbon activated ali ndi makhalidwe angapo, kuphatikizapo mphamvu ya adsorptive, mlingo wa adsorption, ndi mphamvu yonse ya carbon activated.
Kutengera kugwiritsa ntchito (zamadzimadzi kapena gasi), zinthuzi zitha kuwonetsedwa ndi zinthu zingapo, kuphatikiza nambala ya ayodini, malo, ndi Carbon Tetrachloride Activity (CTC).
Kachulukidwe Wowoneka
Ngakhale kachulukidwe kowoneka bwino sikungakhudze adsorption pa kulemera kwa unit, zidzakhudza kutsatsa pa voliyumu ya unit.
Chinyezi
Momwemo, kuchuluka kwa chinyezi chomwe chili mkati mwa kaboni woyatsidwa kuyenera kugwera mkati mwa 3-6%.
Phulusa Zokhutira
Phulusa la carbon activated ndi muyeso wa inert, amorphous, inorganic, and unfortable part of the material. Phulusa lidzakhala lotsika momwe zingathere, momwe mpweya woyatsira mpweya umachulukira pamene phulusa likuchepa.
Mtengo wa pH
Phindu la pH nthawi zambiri limayesedwa kuti liwonetsere kusintha komwe kungachitike pamene mpweya wolowetsedwa wawonjezeredwa kumadzimadzi.
Tinthu Kukula
Kukula kwa tinthu kumakhudza mwachindunji ma adsorption kinetics, mawonekedwe oyenda, komanso kusefa kwa kaboni.
Activated Carbon Production
Activated carbon amapangidwa kudzera njira ziwiri zazikulu: carbonization ndi activation.
Carbonization
Pa carbonization, zopangira ndi thermally kuwola m'malo inert, pa kutentha m'munsimu 800 ºC. Kupyolera mu gasification, zinthu monga mpweya, haidrojeni, nayitrogeni, ndi sulfure, zimachotsedwa pagwero.
Kutsegula
Zinthu zokhala ndi kaboni, kapena char, ziyenera kutsegulidwa kuti zitheke kupanga pore. Izi zimachitika pogwiritsa ntchito oxidizing char pa kutentha pakati pa 800-900 ºC pamaso pa mpweya, carbon dioxide, kapena nthunzi.
Kutengera ndi gwero lazinthu, njira yopangira kaboni wokhala ndi activated imatha kuchitidwa pogwiritsa ntchito matenthedwe (zakuthupi / nthunzi) kuyambitsa, kapena kuyambitsa mankhwala. Mulimonse momwe zingakhalire, ng'anjo yozungulira ingagwiritsidwe ntchito kukonza zinthuzo kukhala kaboni.
Ndife ogulitsa kwambiri ku China, pamtengo kapena zambiri zolandilidwa kulumikizana nafe pa:
