Qhov sib txawv tseem ceeb ntawm cov tshuaj thermochemical thiab biochemical hloov pauv ntawm biomass yog cov txheej txheem hloov pauv cov thermochemical suav nrog cov cua sov ntawm biomass mus rau qhov kub siab, qhov kev hloov pauv biochemical ntawm biomass suav nrog kev pab ntawm cov kab mob.
Thermochemical hloov pauv ntawm biomass yog kev hloov pauv ntawm biomaterials rau hauv cov organic sib txawv yooj yim los ntawm kev siv cov cua sov rau biomass. Kev hloov pauv biochemical ntawm biomass suav nrog kev siv cov kab mob, cov kab mob, thiab cov enzymes rau kev tawg ntawm biomass rau hauv cov roj av lossis kua roj, suav nrog biogas lossis bioethanol.
Dab tsi yog Thermochemical Conversion of Biomass?
Thermochemical hloov pauv ntawm biomass yog kev hloov pauv ntawm biomaterials rau hauv cov organic sib txawv yooj yim los ntawm kev siv cov cua sov rau biomass. Muaj peb txoj hauv kev loj ntawm kev hloov biomass thermochemically rau hauv lwm cov khoom: combustion, gasification, thiab pyrolysis. Cov txheej txheem no tseem tsis tau nthuav tawm kom txog rau thaum lees paub qhov tseem ceeb ntawm txoj hauv kev no hauv kev koom tes hauv catalysis.
Cov txheej txheem hloov pauv thermochemical suav nrog kev siv dej superheated los hloov cov organic teeb meem rau bio-roj. Cov txheej txheem gasification yog ua tiav ntawm qhov kub siab nrog cov ntsiab lus oxygen tsawg nkag mus rau biomass uas tuaj yeem tsim cov roj synthesis, thiab peb tuaj yeem hloov kho cov tshuaj tiv thaiv sib xyaw kom thauj cov roj. Ntxiv mus, cov txheej txheem pyrolysis suav nrog cov cua kub ceev ntawm cov khoom siv biomaterial mus rau qhov kub thiab txias uas tuaj yeem siv los hloov cov organic teeb meem rau bio-crude roj.

Feem ntau, cov txheej txheem kev hloov pauv thermochemical suav nrog kev degradation ntawm biomass qauv nrog oxygenic lossis anoxygenic cua ntawm qhov kub siab. Nws yog ib qho tseem ceeb hauv kev kho cov khoom pov tseg qhov twg gasification muab ob qho txiaj ntsig ntawm kev tsim cov roj muaj txiaj ntsig zoo los ntawm lub zog rov qab los thiab kev pov tseg ib puag ncig tus phooj ywg.
Kev hloov pauv biochemical ntawm Biomass yog dab tsi?
Kev hloov pauv biochemical ntawm biomass suav nrog kev siv cov kab mob, kab mob, thiab cov enzymes rau kev tawg ntawm biomass rau hauv cov roj av lossis kua roj, suav nrog biogas lossis bioethanol. Anaerobic digestion thiab fermentation yog cov kev hloov pauv biochemical ntawm biomass.

Feem ntau, kev zom zaub mov anaerobic cuam tshuam nrog cov tshuaj lom neeg cov tshuaj tiv thaiv raws li kev puas tsuaj ntawm cov khoom siv organic xws li tib neeg pov tseg los ntawm cov kab mob metabolic ntawm cov kab mob uas ib txwm tshwm sim hauv thaj chaw oxygen-depleted. Ntxiv mus, biomass pov tseg tuaj yeem ua kua roj, suav nrog cellulosic ethanol uas tuaj yeem hloov cov roj av raws li roj.
Qhov txawv ntawm Thermochemical thiab Biochemical hloov pauv ntawm Biomass yog dab tsi?
Thermochemical hloov dua siab tshiab thiab biochemical hloov dua siab tshiab yog cov tshuaj lom neeg tseem ceeb uas cuam tshuam nrog biomass ua cov reactant. Qhov sib txawv tseem ceeb ntawm thermochemical thiab biochemical hloov pauv ntawm biomass yog tias cov txheej txheem hloov pauv thermochemical koom nrog cov cua sov ntawm biomass mus rau qhov kub thiab txias thaum biochemical hloov pauv ntawm biomass koom nrog kev pab ntawm cov kab mob. Tsis tas li ntawd, kev hloov pauv ntawm cov tshuaj thermochemical suav nrog kev sib xyaw ua ke, gasification, thiab pyrolysis, qhov hloov pauv biochemical suav nrog kev zom zaub mov thiab fermentation.
Cov hauv qab no qhia txog qhov sib txawv ntawm cov thermochemical thiab biochemical hloov pauv ntawm biomass hauv daim ntawv teev npe rau ib sab ntawm kev sib piv.
Summary – Thermochemical vs Biochemical Hloov pauv ntawm Biomass
Hauv luv luv, thermochemical hloov pauv ntawm biomass yog kev hloov pauv ntawm biomaterials rau hauv cov organic sib txawv yooj yim los ntawm kev siv cua sov rau biomass. Lub caij no, kev hloov pauv biochemical ntawm biomass suav nrog kev siv cov kab mob, cov kab mob, thiab cov enzymes rau kev tawg ntawm biomass rau hauv cov roj av lossis kua roj, suav nrog biogas lossis bioethanol. Qhov sib txawv tseem ceeb ntawm thermochemical thiab biochemical hloov dua siab tshiab ntawm biomass yog tias cov txheej txheem hloov pauv thermochemical koom nrog cov cua sov ntawm biomass mus rau qhov kub siab, qhov kev hloov pauv biochemical ntawm biomass suav nrog kev pab ntawm cov kab mob.
