Mfundo ya activated carbon adsorption

1.Kutengera kapangidwe kake ka pore

Activated carbon ndi mtundu wa microcrystalline carbon zakuthupi zomwe makamaka zopangidwa ndi zinthu za carbonaceous ndi maonekedwe akuda, opangidwa mkati pore dongosolo, lalikulu enieni pamwamba m'dera ndi wamphamvu adsorption capacity. zinthu yaying'ono pores, adzakhala kukod pambuyo pamwamba kufika pa 800-1500 lalikulu mamita, ntchito.Ndiko kuti, m'kati padziko pores mu adamulowetsa mpweya tinthu kukula kwa njere ya mpunga akhoza kukhala Kukula kwa chipinda chochezera. Izi ndizotukuka kwambiri, monga kapangidwe ka pore ya capillary, kotero kuti activated carbon imakhala ndi ntchito yabwino yotsatsa.

Acidated Carbon Adsorption ndi mchitidwe wa kudzikundikira kwa gasi kapena madzi pamwamba pa mpweya wokhazikika, chinthu cholimba cha inert. Njirayi imagwiritsidwa ntchito kuchotsa zowononga zosiyanasiyana, zosungunuka m'madzi, mpweya, ndi mitsinje ya mpweya.

2. Mphamvu ya adsorption pakati pa mamolekyu

Amatchedwanso "van der Waals yokoka". mu adamulowetsa mpweya wamkati pore, chifukwa cha kukopana pakati pa mamolekyu, zidzachititsa kuti mamolekyu ambiri amakopeka, mpaka kudzazidwa adamulowetsa mpweya wamkati pore.

The adamulowetsa mpweya adsorption mfundo: Anapangidwa mu tinthu pamwamba wosanjikiza bwino pamwamba ndende, ndiye zosafunika za organic zinthu adsorbed kuti adamulowetsa mpweya particles, koyamba mkulu adsorption kwenikweni. Koma m'kupita kwa nthawi, adamulowetsa mpweya adsorption mphamvu adzakhala wofooka kwa madigiri osiyanasiyana, ndi adsorption zotsatira komanso reduces. The activated carbon ayenera kuyeretsa nthawi zonse kapena kusintha.
