Gasification ntawm thee yog txheej txheem uas cov thee tau oxidated ib nrab los ntawm huab cua, oxygen, chav lossis carbon dioxide nyob rau hauv tswj cov xwm txheej los tsim cov roj roj. Cov roj kub kub yog txias rau hauv cov khoom siv hluav taws xob, nrog rau kev tsim cov chav, thiab ntxuav ua ntej combustion hauv cov roj turbine.

plaub theem tseem ceeb ntawm cov pa roj carbon monoxide yog dab tsi?

Tom qab cov txheej txheem thee gasification tau muab faib ua ntau pawg, 4 hom txheej txheem thee gasification tau pom raws, cov no yog txav txaj, fluidized txaj, entrained txaj, thiab molten txaj.

Cov pa roj carbon monoxide yog dab tsi Hnub nyoog yog txheej txheem?

Kev tsis txaus ntawm cov pa roj hauv xyoo 1970 thiab '80s ua rau kev tshawb nrhiav ob qho tib si tshiab thiab qub rau kev tsim cov pa roj los ntawm cov thee, ntawm lawv cov txheej txheem tsim nyob rau xyoo 1870 nyob rau hauv uas thee yog pulverized thiab tov nrog oxygen thiab chav nyob rau hauv high kub; txoj kev zoo sib xws siv cua lossis carbon dioxide…

Cov txheej txheem twg ntawm cov txheej txheem gasification yog qhov tseeb?

Cov txheej txheem gasification tuaj yeem muab faib ua 4 cov kauj ruam yooj yim (sketched hauv daim duab 1) uas tshwm sim nyob rau hauv lub reactor tsim nyog: cua sov / ziab, pyrolysis, gas-solids reactions thiab gas phase reactions[1].

syngas formula yog dab tsi?

Qhov no tuaj yeem sib txawv heev nyob ntawm cov khoom noj thiab cov txheej txheem gasification cuam tshuam; Txawm li cas los xij, feem ntau syngas yog 30 to 60% carbon monoxide (CO) , 25 txog 30% hydrogen (H₂), 0 txog 5% methane (CH ₄), 5 mus rau 15% carbon dioxide (CO_{2), ntxiv rau cov dej vapor tsawg los yog ntau dua, tsawg dua ntawm cov sulfur compounds …}
