Laboratory pyrolysis yog txheej txheem tseem ceeb rau kev kawm cov thermal decomposition ntawm cov ntaub ntawv nyob rau hauv kev tswj tej yam kev mob nyob rau hauv tsis muaj oxygen. Cov txheej txheem no tau txais ntau daim ntawv thov thoob plaws hauv kev lag luam xws li cov ntaub ntawv tshawb fawb, kev tshawb fawb ib puag ncig, thiab chemical engineering. Nkag siab txog cov txheej txheem ib ntus thiab cov cuab yeej siv - xws li coviav jacketed pyrolysis reactor rau labkev sim - yog qhov tseem ceeb rau kev ua tiav cov txiaj ntsig raug thiab rov tsim dua. Phau ntawv qhia no dhia mus rau hauv lub hauv paus ntawm kev sim pyrolysis, qhia txog cov kev xav tseem ceeb kom ntseeg tau tias kev sim ua tiav.

Pyrolysis yog dab tsi?
Pyrolysis yog cov txheej txheem thermal decomposition uas tshwm sim thaum cov khoom raug kub siab hauv qhov chaw tsis muaj oxygen. Cov txheej txheem no rhuav tshem cov tebchaw nyuaj rau hauv cov molecules yooj yim, tsim cov pa roj, kua, thiab cov khoom seem zoo li char. Hauv cov chaw kuaj mob, pyrolysis feem ntau yog siv los kawm cov ntaub ntawv muaj pes tsawg leeg, kuaj cov tshuaj tiv thaiv kinetics, thiab tsim cov ntaub ntawv tshiab lossis cov txheej txheem tshuaj.

Cov Khoom Siv Tseem Ceeb: iav Jacketed Pyrolysis Reactor
Lub iav jacketed pyrolysis reactor feem ntau yog siv rau kev sim-scale pyrolysis vim nws qhov tseeb, pob tshab, thiab muaj peev xwm tswj tau qhov kub thiab txias. Lub tsho tsho tsim tso cai rau kev hloov pauv cua sov kom zoo, ua kom muaj cua sov zoo ib yam thoob plaws hauv cov txheej txheem. Cov kws tshawb nrhiav tuaj yeem saib xyuas cov kev cuam tshuam hauv lub sijhawm tiag tiag thiab kho qhov ntsuas raws li qhov xav tau, ua rau hom reactor no zoo tagnrho rau kev tswj xyuas ib puag ncig.

Step-by-Step Txheej Txheem ntawm Laboratory Pyrolysis
1. Kev npaj ua qauv
Xaiv cov khoom siv los kuaj, xyuas kom meej tias nws qhuav thiab hauv av rau hauv cov khoom sib xws yog tias tsim nyog.
Ntsuas tus qauv kom raug kom muaj kev sib xws ntawm kev sim.
2. Chaw thau khoom lub Reactor
Muab cov qauv tso rau hauv lub reactor cov tshuaj tiv thaiv chamber.
Kaw lub reactor kom nruj kom tsis txhob muaj oxygen nkag mus rau hauv lub sijhawm ua haujlwm.
3. Teem Cov Kev Ntsuas Kev Ntsuas
Teem qhov ntsuas kub qhov xav tau, feem ntau ntawm 300 ° C thiab 900 ° C, nyob ntawm cov khoom siv thiab cov hom phiaj kev sim.
Kho tus nqi cua sov kom tswj tau qhov ceev ntawm thermal decomposition.
4. Inert Gas Purge
Qhia cov roj inert, xws li nitrogen los yog argon, kom tshem tawm cov pa oxygen seem.
Ua kom tsis tu ncua ntawm cov pa roj inert thoob plaws hauv qhov kev sim kom ntseeg tau tias qhov chaw tsis muaj oxygen.
5. Theem cua sov
Maj mam ua kom sov lub reactor raws li pre-set kub profile.
Saib xyuas qhov kub thiab txias hloov, raws li tus nqi ntawm decomposition tuaj yeem sib txawv nrog qhov kub thiab txias.
6. Cov khoom ntim khoom
Raws li pyrolysis tshwm sim, sau cov pa roj, kua, thiab cov khoom lag luam los ntawm cov khoom tsim nyog.
Siv condensation lossis filtration systems cais thiab ntes txhua theem rau kev tshuaj xyuas ntxiv.
7. Txias thiab tshuaj xyuas
Tom qab ncav cuag lub hom phiaj kub thiab tuav rau lub sijhawm xav tau, maj mam txias lub reactor rov qab rau hauv chav tsev kub.
Txheeb xyuas cov khoom sau los ntawm cov txheej txheem xws li roj chromatography, huab hwm coj spectrometry, lossis thermal gravimetric tsom xam.

Cov ntsiab lus tseem ceeb rau kev ua tiav Pyrolysis
• Tswj Kev Kub Kub: Kev tswj xyuas cov cua kub thiab lub hom phiaj kub yog qhov tseem ceeb rau kev rov tsim dua tshiab thiab raug.
• Inert Atmosphere: Txhua qhov muaj oxygen tuaj yeem ua rau combustion es tsis yog pyrolysis, hloov cov txiaj ntsig tau zoo.
• Sample Size thiab Uniformity: Cov qauv piv txwv zoo ib yam thiab kev faib tawm tsis sib xws hauv lub reactor txhim kho qhov kev ntseeg siab ntawm cov txiaj ntsig kev sim.
• Kev Ntsuas Kev Nyab Xeeb: Cov txheej txheem kub kub yuav tsum muaj cov txheej txheem kev nyab xeeb kom raug, suav nrog cov cuab yeej tiv thaiv thiab qhov cua kom raug.
