I-Carbon Esebenzayo - Amafomu Okukhiqiza kanye Nomkhiqizo

The kokuqala izinto zokukhiqiza okusebenzayo I-Carbon yilezi: izinto zokusetshenziswa eziqukethe ikhabhoni njengokhuni, i-peat, i-lignite, amalahle aqinile, izinhlamvu zezithelo ezifana nemigodi yomnqumo, Shell Coconuts, njll. Ukusebenza kwalezi zinto kungenziwa kusetshenziswa izindlela ezimbili ezahlukene.

Ekusebenzeni kwegesi, izinto ezivele zifakwe i-carbon ziyasetshenziswa futhi zichayeke ethonyeni le-oxidizing lomfula wegesi, njengomhwamuko wamanzi, i-carbon dioxide, umoya, noma izingxube zawo. izinga lokushisa lokusebenza licishe libe ngu-700–1000°C, lapho ikhabhoni ishiswa khona kancane ngemva kokusabela kwamanzi negesi, ngaleyo ndlela kwakha uhlaka lwekhabhoni olunezimbobo, olusebenza kakhulu.

Ekusebenzeni kwamakhemikhali, umuntu uvame ukuhlanganisa izinto ezingenayo i-carbon, eziqukethe i-carbon namakhemikhali aqeda amanzi emzimbeni nakhipha i-oxidation. Ingxube ephumayo bese ishiswa ku-400–800°C. Izinto ezivuselelayo—ezingafaka i-zinc chloride, i-phosphoric acid, i-sulfuric acid, nezinye—kamuva ziyagezwa bese zibuyiswa.

Ukusebenza ngokwako kwenziwa kuma-rotary kilns, ama-multi-stage kilns, ama-shaft kilns, ama-bed kilns agcwele uketshezi, noma ama-reactor e-bed agcwele uketshezi.

Umkhiqizo ojwayelekile wakha Ikhabhoni Esebenzayo yilezi:

ezibunjwe ngendlela (ikakhulukazi ngesimo sama-pellets asilinda),

ephukile (ama-granules noma i-activated carbon echotshoziwe),

i-powdered ngobukhulu bezinhlayiya ezichaziwe.

Izindlela zokukhiqiza ezikhethekile zifaka:

ikhabhoni esebenzayo eyindilinga,

imicu yekhabhoni esebenzayo noma ama-fiber mats,

okubizwa ngokuthi “ama-honeycombs.”

Izindlela zokukhiqiza kanye nokwenza kusebenze, kanye nezinto zokusetshenziswa eziyisisekelo, zithonya kakhulu izakhiwo zekhabhoni esebenzayo maqondana namandla ayo okumunca ngesikhathi sokusetshenziswa. Ikakhulukazi, ubukhulu bendawo yangaphakathi kanye nesakhiwo sembobo kuncike kakhulu enkambisweni yokwenza kusebenze.
