Qhov sib txawv tseem ceeb ntawm cov pa roj carbonization thiab gasification yog cov pa roj carbonization yog qhov kev ywj pheej ntawm cov khoom lag luam tsis hloov pauv los ntawm cov khoom siv hluav taws xob thaum cua sov, qhov kev hloov pauv ntawm biomass rau hauv cov khoom siv roj (syngas) thaum cua sov.
Coal carbonization thiab gasification yog cov txheej txheem tseem ceeb uas suav nrog cov thee ua lub ntsiab reactant. Cov txheej txheem no muab cov seem tseem ceeb rau kev kho cua sov.
Coal Carbonization yog dab tsi?
Coal carbonization yog txheej txheem ntawm cov cua sov thee, uas ua rau cov khoom tsis hloov pauv kom dim ntawm cov thee, tawm ntawm cov khoom seem. Cov khoom seem no hu ua coke. Cov khoom volatile hauv thee tuaj yeem ua kua lossis roj, lossis nws tuaj yeem yog ob qho tib si. Nyob rau hauv cov txheej txheem no, peb yuav tsum tau ua kom sov thee mus rau qhov kub thiab txias. Peb tuaj yeem ua qhov cua sov no txawm tias tsis muaj oxygen lossis nyob rau theem tswj cov pa oxygen.
Daim duab 01: Carbonization
Feem ntau, lo lus carbonization yog hais txog kev hloov pauv ntawm cov organic teeb meem (xws li cov nroj tsuag thiab cov khoom tsiaj tuag) rau hauv cov pa roj carbon monoxide los ntawm cov txheej txheem tshuaj xyuas hu ua destructive distillation. Destructive distillation yog decomposition ntawm unprocessed cov khoom siv tshav kub, ua raws li los ntawm kom zoo extraction.
Cov txheej txheem ntawm carbonization tshwm sim raws li cov tshuaj tiv thaiv pyrolytic, thiab nws yog cov txheej txheem nyuaj uas muaj ntau yam tshuaj lom neeg tshwm sim ib txhij. Cov tshuaj tiv thaiv no suav nrog dehydrogenation, condensation, hloov hydrogen, thiab isomerization.
Ntxiv mus, carbonization txawv ntawm coalification vim coalification yog sib piv ceev heev vim muaj cov tshuaj tiv thaiv siab.
Gasification yog dab tsi?
Gasification yog cov txheej txheem thermo-chemical uas hloov biomass rau hauv cov pa hluav taws xob hu ua cov khoom siv roj (syngas). Ntawm no, cov ntaub ntawv decompose nyob rau hauv ib puag ncig uas muaj me me ntawm oxygen. Txawm li cas los xij, cov pa oxygen no tsis txaus rau combustion. Cov khoom ntawm gasification yog cua sov thiab combustible gas.
Ntxiv mus, cov txheej txheem pib ntawm qhov kub ntawm 800 ° C - 1200 ° C. Cov khoom tseem ceeb hauv cov roj hluav taws xob uas tsim los ntawm cov txheej txheem no suav nrog carbon monoxide thiab hydrogen gas. Tsis tas li ntawd, muaj lwm yam khoom xws li dej vapor, carbon dioxide, tar vapour, thiab tshauv.
Daim duab 02: Ntau hom Gasifiers
Nyob rau hauv lub gasifier qhov twg gasification tshwm sim nyob rau hauv industrial theem, peb siv tau ntau hom feedstock; Peb tuaj yeem faib cov yam ntxwv xws li qhov loj me, cov ntsiab lus siv tshuaj, cov khoom siv hluav taws xob, thiab cov nplais, thiab cov dej phwj tuaj sludge, etc.
Qhov txawv ntawm Coal Carbonization thiab Gasification yog dab tsi?
Coal carbonization thiab gasification yog cov txheej txheem tseem ceeb uas suav nrog cov thee ua lub ntsiab reactant. Qhov sib txawv tseem ceeb ntawm cov pa roj carbonization thiab gasification yog cov pa roj carbonization yog qhov kev ywj pheej ntawm cov khoom tsis zoo los ntawm cov khoom siv hluav taws xob thaum cua sov, hos gasification yog hloov pauv ntawm biomass rau hauv syngas thaum cua sov. Ntxiv mus, cov khoom kawg ntawm cov pa roj carbonization yog coke, thee tar, soot, thiab hydrocarbon gases, thaum kawg cov khoom ntawm gasification yog khib nyiab, tshauv, slags, thiab syngas.
Cov hauv qab no infographic teev qhov sib txawv ntawm cov pa roj carbonization thiab gasification nyob rau hauv daim ntawv tabular rau ib sab ntawm kev sib piv.
Summary – Coal Carbonization vs Gasification
Hauv kev lag luam hydrocarbon, thee yog ib qho tseem ceeb reactant uas tuaj yeem ua ntau yam txheej txheem, xws li carbonization thiab gasification. Qhov sib txawv tseem ceeb ntawm cov pa roj carbonization thiab gasification yog cov pa roj carbonization yog kev ywj pheej ntawm cov khoom tsis hloov pauv los ntawm cov khoom siv hluav taws xob thaum cua sov, whereas gasification yog hloov dua siab tshiab ntawm biomass rau hauv syngas thaum cua sov.
