Qhib Alumina, raws li ib tug muaj cov ntaub ntawv tshaj tawm, tuaj yeem siv los tshem cov chlorides (xws li HCl, CleChochlorine, thiab lwm yam) los yog kua.
1, lub hauv paus ntsiab lus ntawm dechlorination los ntawm acumina
A, lub cev adsorption: nws lub cev adsorbs chlorine lwg me me los ntawm kev vam khom ntawm thaj chaw siab (} m² \/ g) thiab tus qauv poj niam.
B, Tshuaj Adsorption: Cov pab pawg hydoxyl (-oh) tuaj yeem hnov mob nrog HCL thiab lwm yam khoom los ua alcl₃ lossis chloroaluminate (tshuaj lom neeg sib koom tes).
C, Kev Hloov Kho thiab Txhim Kho: Los ntawm impregnating alkaline tej yam (xws li Naoh, K₂CO₃ muaj peev xwm rau Acidic Chlorides (xws li HCl) tau zoo dua.
2. Siv tau cov xwm txheej
A, roj kev txiav txim siab
Lub hom phiaj ua qias tuaj: HCl, Clj, Ecoroclorine (xws li Ch₂cl₂).
Muaj feem xyuam mob:
Qhov kub thiab txias: Chav tsev kub txog 200 degree (thermal kev hloov kho kev ruaj ntseg yog qhov yuav tsum tau ua thaum kub siab).
Vaum: Nkag mus rau dej, ua ntej kom qhuav yog tseev kom muaj lossis hydrophobic hloov alumina yuav tsum tau xaiv.
Kev sib tw Adsorption: Yog tias cov roj muaj cov taum, h₂s, thiab lwm yam, nws yuav nyiam cov adsorbed, txo cov kev ua kom zoo.
B, kua dechlorination
Lub hom phiaj ua qias tuaj: yaj cov chlorine, chlorinated organic sib dhos (xws li chloroform).
Txwv Txwv:
Tshem tawm cov khib nyiab hauv cov kua yuav txhaws qhov hws thiab xav tau pretreatment thiab pom.
Cwj Phaj: Cov Ntawv Qhia Tawm Tsam HCL yog zoo dua nyob rau hauv acidic tej yam kev mob.
C, kev siv
Natural pa dechlorination: Tshem tawm HCL los ntawm cov pub nyiaj pub tiv thaiv cov dej hauv av cataltlest.
Petrochemical Kev Lag Luam: tshem tawm ortochlorine (xws li R-CL) los ntawm hydrocarbons los tiv thaiv cov khoom siv corrosion.
WASTEWater Kev Kho Mob: Adsorb Chloride Eons hauv Wastewater (hloov kho lossis sib xyaw nrog lwm cov ntaub ntawv yuav tsum tau).
