Kauj ruam 1: Charring
Thawj kauj ruam los ua cov txiv maj phaub-plhaub activated carbon yog xyuas kom cov txiv maj phaub siv tau ntxuav thiab qhuav nrog cov fibers sab nrauv tshem tawm. Tom qab qhov no tau ua tiav, cov txiv maj phaub plhaub yuav tsum tau mus txog thawj theem, uas yog txhawm rau txhawm rau lawv.
Txhawm rau ua qhov no, lawv yuav tsum raug kub siab heev, nrog rau qhov zoo tshaj plaws kub ntawm 500-600 degrees Celsius lossis 932-1,112 degrees Fahrenheit rau ntau teev. Nws thiaj li (feem ntau hauv 12 teev), cov txiv maj phaub plhaub yuav dhau los ua hluav taws.
Ib txoj hauv kev nrov tshaj plaws rau cov pa roj carbon activated tshwm sim hauv lub nruas kiln nrog lub chimney. Txij li thaum nws muaj lub chimney, lub nruas kiln tuaj yeem tsim kom muaj qhov kub siab dua sab hauv los ntawm kev txwv cov pa oxygen txaus. Feem ntau cov txiv maj phaub plhaub nyob rau hauv qab ntawm lub nruas kiln yuav carbonize ua ntej.
Kauj Ruam 2: Pacification
Cov kauj ruam tom ntej ntawm cov txiv maj phaub carbon activation txheej txheem yog pacification. Pacification txhais tau hais tias cov cua ntws tag nrho raug txiav tawm hauv qab ntawm lub nruas kiln, uas tso cai rau cov coals pib txias. Cov txheej txheem no yog qhov tseem ceeb heev rau kev tsim cov txiv maj phaub-plhaub activated carbon vim tias yog qhov kub hnyiab tas li, cov thee tsim yuav tig mus rau tshauv.
Kauj Ruam 3: Kev Ua Haujlwm Chav
Thaum cov thee npaj tau lawm, cov kauj ruam tom ntej yog qhib kom ua lub lim. Lub hom phiaj tseem ceeb ntawm kev ua kom cov txiv maj phaub plhaub carbon yog txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhaws.
Feem ntau muaj ob txoj hauv kev los qhib cov txiv maj phaub plhaub carbon - los ntawm soaking nws nyob rau hauv cov tshuaj xws li phosphoric acid, los yog nws yuav tsum tau qhib los ntawm chav, raws li tau hais yav tas los.
Rau steaming, qhov kub hauv lub cub tawg yuav tsum tau coj mus rau ib ncig ntawm 1, 470-2,010 degrees Fahrenheit. Qhov scorching chav no yuav dehydrate cov pa roj carbon, uas tso cai rau cov qib ntawm volatile organic compounds (VOCs) nyob rau hauv nws yuav tsum tau txo.
Thaum cov txiv maj phaub roj yog steamed, nws cov pores yuav loj kom txog thaum lawv loj txaus kom ntes cov molecules hauv dej.
