Cov txheej txheem pyrolysis yog dab tsi? Xauv cov kev tshem tawm ruaj khov-rau-lub zog daws teeb meem

Txoj kev tshawb fawb ntawm cov txheej txheem pyrolysis ua rau nkag siab txog cov khoom siv thermipgen thaum muaj cov roj ntsha (biochar). Cov khoom lag luam muaj ntau yam siv, xws li roj ntau lawm, kev txhim kho av thiab kev txhim kho tshiab} Nyob rau hauv cov khoom pov tseg thiab cov peev txheej niaj hnub no tau siv rau kev txo qis thiab cov peev txheej rov qab {}}

Cov Ntsiab Lus Tseem Ceeb:
Cov txheej txheem pyrolysis yog dab tsi? Xauv cov kev tshem tawm ruaj khov-rau-lub zog daws teeb meem
Pyrolysis Cov Lus Txhais thiab Mechanism:

Pyrolysis yog cov thermochemical decomprosition ntawm cov ntaub ntawv organic ntawm cov khoom kub (feem ntau {{} {} degree) thaum tsis muaj pa o6ygen {}}

Txoj kev no tsoo cov neeg sib txuas lus rau hauv cov khoom siv cov lwg me me, suav nrog roj av me, suav nrog gases, kua thiab khib .

Nws yog irreversible thiab yuav cuam tshuam ob lub cev thiab tshuaj hloov kho .

Lub ntsiab Cheebtsam ntawm cov pyrolysis cog:

Reactor: cov tub ntxhais tivthaiv uas ua kom sov thiab decomposes cov khoom .

Kev tswj qhov kub thiab txias: tswj qhov siab kub (400-900} degree) yuav tsum tau ua kom zoo decomposition.
Kev nyab xeeb thiab tswj lub tshuab: kom ntseeg tau tias muaj txiaj ntsig thiab kev nyab xeeb ntawm cov txheej txheem .
Cov zis tuav: Cov tshuab rau kev sau thiab ua cov khoom tsim tawm, cov roj-roj thiab biochar.
Pyrolysis khoom:

Syngas: kev sib xyaw ntawm cov roj (e {{{{} hydrogen, carbon monoxide) uas tuaj yeem siv roj carbon monoxide (roj carbon monoxide) uas tuaj yeem siv roj carbon monoxide.
Bio-Roj: Cov khoom ua kua uas tuaj yeem ua kom zoo rau kev thauj mus los lossis kev siv cov khoom siv.
Biochar: ib qho chaw seem uas tuaj yeem siv los ua cov av txias lossis adsorbent rau ib puag ncig cov ntawv thov {}}}}}}
Cov ntawv thov ntawm pyrolysis:

Khib Nyuaj: Hloov cov tshuab hluav taws xob, plastics thiab log tsheb rau cov khoom muaj txiaj ntsig zoo txo ​​cov chaw khib nyiab pov tseg {}}
Hluav taws xob ntau: syngas thiab roj-roj tuaj yeem siv raws li lub zog txuas dua tshiab .
Kev Txhim Kho Av: Biochar txhim kho cov av fertility thiab carbon Secitteration .
Kev Tsim Khoom Siv Tshuaj Lom Zem: Kua thiab Gases tsim los ntawm pyrolysis tuaj yeem siv los ua cov khoom noj rau cov neeg siv tshuaj rau kev siv tshuaj lom neeg {}}
Keeb kwm keeb kwm ntawm pyrolysis:

Pyrolysis tau nyob ib puag ncig txij puag thaum ub, piv txwv li, hauv kev tsim cov hluav taws xob los ntawm ntoo .
Cov neeg Iyiv thaum ub tau siv cov kua uas tsim los ntawm pyrolysis hauv lawv cov txheej txheem embalming .
Cov txheej txheem tau pab nrhiav tshuaj xyuas cov tshuaj tseem ceeb, suav nrog phosphorus thiab oxygen .
Cov kev sib tw thiab kev saib xyuas:

Lub zog siv: pyrolysis yuav tsum muaj ntau lub zog cov tswv yim los tswj hwm siab kub .
Cov txheej txheem optimization: Kho kom tswj tau ntawm qhov ntsuas kub, lub siab, thiab cov kev sib tw yog qhov tsim nyog los ua kom zoo tshaj cov khoom lag luam tawm thiab zoo .
Feedstock kev sib txawv: cov khoom sib xyaw ntawm cov ntaub ntawv tawm tswv yim tuaj yeem cuam tshuam rau cov khoom tso zis, yog li cov txheej txheem customized yuav tsum .
Kev nce qib niaj hnub no hauv Pyrolysis:

Txhim kho cov tshuaj tiv thaiv reactor: nce kev ua tau zoo thiab ruaj khov ntawm cov txheej txheem .
Kev koom ua ke nrog lwm cov thev naus laus zis: ua ke pyrolysis nrog cov roj av lossis cov txheej txheem catalytic los txhim kho cov khoom lag luam zoo .
Kev Ua kom muaj kev ua kom pom tseeb: kev txhim kho txoj hauv kev los txo kev siv zog thiab ib puag ncig cuam tshuam {}}
Los ntawm kev kawm cov txheej txheem pyrolysis, cov kws tshawb nrhiav thiab cov kws siv tshuab tsim kho kom zoo, yog cov peev txheej ntxiv, yog cov peev txheej ntxiv, yog cov peev txheej ntxiv ua haujlwm, yog muaj peev xwm pab txhawb nqa cov kev lag luam zoo nkauj ntxiv {}}
