Kev xaiv tsis zoo ntawm cov pa roj carbon activated ua rau muaj kev puas tsuaj loj thiab lub neej luv luv. Feem ntau, nws yuav tsum tau hloov txhua txhua 6 lub hlis mus rau 1 xyoo, thiab tus nqi ntawm kev hloov cov pa roj carbon activated yog siab heev. Tshwj xeeb activated carbon muaj peev xwm adsorption tshaj 100% thiab zoo adsorption thiab stability, ua rau lub neej ntawm 2-3 xyoo los yog ntau tshaj thiab txuag nqi. Qhov tshwj xeeb ntawm qhov chaw thiab qhov pore qauv ntawm cov pa roj carbon activated yog qhov zoo sib xws. Cov kuab tshuaj organic sib txawv xav tau cov pa roj carbon activated nrog qhov sib txawv ntawm qhov pore los xyuas kom meej qhov tsawg kawg nkaus attenuation, tsis tshua muaj roj siab tsis kam, muaj zog adsorption muaj peev xwm, thiab yooj yim desorption. Qhov no ua kom cov roj ntws nrawm nrawm thiab tshem tawm cov xwm txheej kub hauv zos.
Cov pa roj carbon activated rau cov organic pov tseg kev kho mob muaj qhov zoo ntawm qhov tsim nyog qhov pore loj, muaj peev xwm adsorption ceev, ceev ceev adsorption, siab txhua yam muaj zog, siv nyob rau hauv lub txaj ruaj, tsis tshua muaj roj txaus tsis kam, yooj yim desorption thiab rov tsim dua tshiab, thiab lwm yam.
Indicators of activated carbon for organic pov tseg gas kho:
Adsorption ntsuas:Carbon tetrachloride CTC, zoo, siab dua 100% benzene adsorption: zoo, siab dua 50% acetone adsorption: siab dua 50%
Kev siv zog:70-90% lossis siab dua, nyob ntawm daim ntawv thov tshwj xeeb. Lub zog siab dua, qhov zoo dua. Qhov siab dua lub zog, qhov qis dua qhov adsorption yuav yog.
Loj:Qhov kev faib ua feem ntau dua, tus nqi ntau dua, qhia tias qhov tshwj xeeb ntawm thaj chaw me me thiab ruaj khov dua. Qhov loj dua qhov tshwj xeeb lub ntiajteb txawj nqus ntawm tib lub voos xwmfab, qhov hnyav dua.
Cov ntsiab lus tshauv:qis dua 6%, noo noo cov ntsiab lus<5%. Impurities that are too high can also affect adsorption and cost.
Hluav taws kub taw tes:>450 degrees
Khoom siv:Feem ntau xaiv ntoo lossis thee, txiv maj phaub plhaub tsis haum vim tias cov kuab tshuaj organic xav tau mesoporous activated carbon. Yog tias cov thee ua tau raws li cov lus qhia saum toj no, tus nqi yuav siab dua ntoo. Ordinary thee raws li cov pa roj carbon CTC50-70% benzene adsorption: 20-40% ntoo tshuajCov pa roj carbon activated:CTC: 100% -140% benzene adsorption: 45-60% lub ntiajteb txawj nqus tsuas yog ib nrab ntawm cov thee.
Organic pov tseg gas kev kho mob activated carbon kho txoj kev
Los ntawm adsorbing pa pa nrog activated carbon, thaum lub adsorption yog saturated, cov activated carbon desorbs thiab regenerates, tshuab tawm cov pa pa thiab catalyzing combustion kom hloov mus rau hauv cov khoom tsis muaj teeb meem. Cov regenerated activated carbon tseem siv tau. Thaum lub peev xwm adsorption ntawm cov pa roj carbon activated poob qis tom qab qee qhov kev tsim kho tshiab, nws yog qhov tsim nyog yuav tsum rov tsim dua lossis hloov kho cov activated carbon. Cov pa roj carbon activated tam sim no yog txoj hauv kev uas feem ntau siv los kho cov pa roj carbon monoxide, nrog rau kev ua haujlwm zoo rau benzene khib nyiab, tab sis tsis zoo adsorption kev ua tau zoo rau hydrocarbon pov tseg roj. Lub ntsiab tsis zoo yog qhov kev khiav hauj lwm tus nqi siab thiab nws tsis haum rau ib puag ncig nrog cov av noo siab. Txawm li cas los xij, rau cov ntawv thov kev lag luam tam sim no, activated carbon adsorption yog txoj kev siv ntau tshaj plaws.
