Supercritical Co2 Systems Rau Cov Extraction

Lub hauv paus ntsiab lus ntawm supercritical carbon dioxide extraction txheej txheem yog siv supercritical carbon dioxide kom muaj kev tshwj xeeb solubility los ntawm tej yam ntuj tso khoom tshwj xeeb, siv kev sib raug zoo ntawm dissolution ntawm supercritical carbon dioxide thiab nws qhov ntom, uas yog, cov nyhuv ntawm siab thiab kub rau. supercritical carbon dioxide dissolution muaj peev xwm txuas ntxiv mus. Nyob rau hauv lub xeev supercritical, supercritical carbon dioxide yog hu rau cov khoom yuav tsum tau muab cais los ntawm kev xaiv extract lub polarity magnitude, lub boiling point, thiab lub molecular hnyav sib txawv Cheebtsam. Ntawm chav kawm, cov extracts tau txais nyob rau hauv txhua lub siab ntau yam tsis tuaj yeem yog ib leeg, tab sis cov xwm txheej tuaj yeem tswj tau kom tau txais qhov zoo tshaj plaws ntawm cov khoom xyaw sib xyaw, thiab tom qab ntawd los ntawm kev txo qis, qhov kub ntawm qhov kub hloov cov kua supercritical rau hauv cov pa roj. , thiab cov ntaub ntawv rho tawm tiav los yog yooj yim los nag, lub hom phiaj ntawm kev sib cais purification yog tiav, yog li cov txheej txheem supercritical kua carbon dioxide extraction yog tsim los ntawm kev rho tawm thiab sib cais.
