Glycerol, raws li cov khoom siv raw khoom tseem ceeb, pom kev siv dav hauv kev lag luam xws li zaub mov, tshuaj, thiab tshuaj pleev ib ce. Cov khoom siv raw rau kev lag luam glycerol feem ntau yog los ntawm cov khoom lag luam ntawm biodiesel thiab oleochemicals. Tom qab distillation, condensation, thiab decolorization, cov khoom kawg tau txais.
Activated Carbon rau Glycerol Decolorization
Txoj kev tseem ceeb tam sim no rau glycerol decolorization yog tsau-txaj decolorization. Hauv cov txheej txheem no, ntau npaum li cas ntawm cov pa roj carbon activated tau ntim rau hauv lub tank decolorization. Glycerol nkag mus rau sab saum toj ntawm qhov ntsuas kub thiab ntws tus nqi, maj mam dhau los ntawm cov pa roj carbon activated. Cov micropores ntawm cov pa roj carbon activated adsorb impurities hauv glycerol.
Cov pa roj carbon activated tuaj yeem tsis tsuas yog adsorb xim tshuaj, tab sis kuj pom muaj zog xaiv rau ntau hom pigments. Qhov kev tshem tawm lub hom phiaj no txhim kho qhov purity ntawm glycerol thaum lub sij hawm decolorization txheej txheem.
Los ntawm kev siv cov pa roj carbon activated rau glycerol decolorization, qhov tso tawm ntawm cov khoom tsis zoo rau hauv cov dej khib nyiab tau txo qis, txo qhov cuam tshuam ib puag ncig.
