Qhov sib txawv tseem ceeb ntawm pyrolysis thiab gasification yog tias pyrolysis ua tiav thaum tsis muaj cua thaum gasification ua tiav hauv huab cua.
Pyrolysis thiab gasification yog ob txheej txheem tseem ceeb uas siv los decompose cov ntaub ntawv. Ob qho txheej txheem no txawv ntawm kev sib xyaw vim tias qhov sib xyaw ua ke tau ua nyob rau hauv qhov muaj cov pa oxygen ntau dhau.
YPyrolysis yog dab tsi?
Pyrolysis yog cov txheej txheem thermal hloov ntawm cov organic teeb meem uas siv cov catalyst thaum tsis muaj oxygen. Yog li ntawd, nws yog decomposition ntawm cov khoom nyob rau hauv ib tug inert cua. Nws yog ib qho tshuaj tiv thaiv uas suav nrog kev hloov pauv ntawm cov tshuaj muaj pes tsawg leeg ntawm cov khoom. Ntxiv mus, nws yog ib txoj kev rov qab los.

Nyob hauv pyrolysis, qhov peb ua yog cua sov cov khoom mus rau qhov kub siab tshaj qhov kub decomposition. Nws rhuav tshem cov chemical bonds ntawm cov khoom. Yog li ntawd, cov txheej txheem no feem ntau tsim me me molecules los ntawm cov tawg loj. Txawm li cas los xij, cov molecules me me no tuaj yeem ua ke, tsim cov molecular loj thiab. Piv txwv li, pyrolysis ntawm triglycerides tsim alkanes, alkenes, alkadienes, aromatics thiab carboxylic acids.
Gasification yog dab tsi?
Gasification yog cov txheej txheem thermo-chemical uas hloov biomass mus rau hauv cov pa hluav taws xob hu ua cov khoom siv roj (syngas). Ntawm no, cov ntaub ntawv decompose nyob rau hauv ib qho chaw uas muaj me ntsis ntawm cov pa 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. Lub hauv paus ntsiab lus ntawm cov roj combustible uas tsim thaum lub sij hawm txheej txheem no muaj xws li carbon monoxide thiab hydrogen gas. Tsis tas li ntawd, muaj qee yam khoom siv xws li dej vapor, carbon dioxide, tar vapour, tshauv, thiab lwm yam.
Qhov txawv ntawm Pyrolysis thiab Gasification yog dab tsi?
Pyrolysis yog cov txheej txheem thermal hloov ntawm cov organic teeb meem uas siv cov catalyst thaum tsis muaj oxygen. Gasification yog cov txheej txheem thermo-chemical uas hloov cov biomass rau hauv cov pa hluav taws xob hu ua cov khoom siv roj (syngas). Qhov sib txawv tseem ceeb ntawm pyrolysis thiab gasification yog tias pyrolysis yog ua tiav thaum tsis muaj huab cua thaum gasification ua rau muaj huab cua. Tsis tas li ntawd, cov khoom ntawm pyrolysis yog cua sov thiab combustible kua thiab combustible gas thaum cov khoom ntawm gasification muaj xws li kub thiab combustible gas. Yog li, qhov no kuj yog qhov sib txawv ntawm pyrolysis thiab gasification.
Ntxiv mus, pyrolysis yog qhov tseem ceeb rau kev siv hauv kev tsim khoom noj, piv txwv li caramelization, tsim cov roj los ntawm biomass, tsim cov ethylene, kho cov khib nyiab yas, thiab lwm yam thaum gasification muaj txiaj ntsig rau kev tsim hluav taws xob, tsim hluav taws xob, thiab lwm yam.
Summary – Pyrolysis vs Gasification
Pyrolysis yog cov txheej txheem thermal hloov ntawm cov organic teeb meem uas siv cov catalyst thaum tsis muaj oxygen. Gasification, ntawm qhov tod tes, yog cov txheej txheem thermo-chemical uas hloov biomass rau hauv cov pa roj. Qhov sib txawv tseem ceeb ntawm pyrolysis thiab gasification yog tias pyrolysis ua tiav thaum tsis muaj huab cua thaum gasification ua tiav ntawm huab cua.
