Cov txheej txheem ntau lawm ntawm spherical activated carbon ntau yog muaj peb cov khoom siv tseemceeb
Thaum lub sij hawm raw khoom ntawv ua ntej theem, petroleum asphalt lossis hluavtaws resin yog feem ntau xaiv los ua cov khoom siv raw. Tom qab tau melted ntawm qhov kub, kheej kheej ua ntej, kheej kheej ua ntej diameters ntawm 0.5-3mm tau npaj los ntawm cov tshuaj tsuag lossis cov txheej txheem emulsification.
Cov txheej txheem hloov dua siab tshiab tau muab faib ua ob kauj ruam tseem ceeb: oliidation stabilization kev tswj hwm tau nce ntawm 500-8 Qib kom tiav cov qauv hluav taws xob.
Thaum lub sijhawm ua haujlwm, chav (800 - 950 degree) lossis thaum kawg ib cheeb tsam huab cua ntawm 500400m² / g tuaj yeem tau txais. Txhawm rau txhim kho cov khoom lag luam ntxiv, cov txheej txheem kev kho mob tom qab xws li ammonia kev hloov kho lossis hlau thauj khoom tuaj yeem siv. Cov khoom tiav tiav yuav tsum tau ua tiav qhov qhia nruj me me xws li sphericity> 95% thiab compressive muaj zog> 10n ib thooj. Nws cov txheej txheem sib txawv ib txwm tuaj yeem txo cov txaj lub siab poob los ntawm ntau dua 40% piv nrog cov carbon zoo ib ce.
Tus tseem ceeb tswj cov ntsiab lus ntawm tus txheej txheem no suav nrog: kev tswj hwm kev ua kom zoo ntawm cov txheej txheem cua sov, thiab kev hloov kho kom zoo ntawm cov roj teeb hauv cov theem ua pa. Cov thev naus laus zis thev naus laus zis tau qhib cov khoom lag luam los ua kom pom qhov tseem ceeb hauv kev ua haujlwm siab xws li cov ntshav huv si thiab kev tiv thaiv tub rog.
