Genetic Differences nyob rau hauv Raw Materials thiab txheej txheem
Txawm hais tias biochar thiab coke yog ob qho tib si cov khib nyiab dub, lawv cov keeb kwm txawv txawv:
Biochar: Muab tau los ntawm kev ua liaj ua teb thiab hav zoov pov tseg xws li cog stalks thiab txiv hmab txiv ntoo husks, nws nkag mus rau cov pa oxygen -limited pyrolysis ntawm 400-}700℃, zoo li muab cov organic teeb meem "kub-kub spa," khaws cia nws cov qauv ntxeem tau.
Coke: Muab tau los ntawm cov thee los ntawm qhuav distillation ntawm ntau tshaj 1000 degree, sib npaug rau "hellish forging" ntawm cov thee, ua rau cov ntsiab lus carbon ntau dua 90% thiab porosity tsawg.
Qhov zais cia ntawm lub cev muaj zog
Raws li lub tshuab tsom, lawv zoo li ob hom "honeycombs":
Cov cheeb tsam tshwj xeeb: Biochar tuaj yeem ncav cuag 300 m² / g (sib npaug rau qhov chaw ncaws pob), thaum coke feem ntau tsawg dua 50 m² / g.
Adsorption muaj peev xwm: Biochar tuaj yeem nqus tau 20% ntawm nws tus kheej qhov hnyav hauv cov pa phem, thaum coke feem ntau yog siv rau kev sib xyaw thiab tsim hluav taws xob.
pH tus nqi: Biochar yog alkaline (pH 8-10), thaum coke yog ze rau nruab nrab.
Lub Watershed of Application Scenarios
Cov "cov kwv tij carbon" no ci hauv lawv qhov chaw:
Biochar: Ib tug "tus kws qhia noj zaub mov" rau kev txhim kho av, "tus neeg saib xyuas ib puag ncig" rau cov pa roj carbon dioxide sequestration, thiab kuj siv rau kev kho cov dej khib nyiab thiab cov pa pa.
Coke: Ib qho "pob lub zog" rau cov hlau smelting, "kub qhov chaw" rau kev lag luam casting, thiab ib feem yog siv los tsim cov khoom siv tshuaj xws li calcium carbide.
