Microalgae tuaj yeem hloov cov pa roj carbon dioxide hauv cov pa roj thiab nitrogen, phosphorus, thiab lwm yam kuab paug hauv dej pov tseg rau hauv biomass los ntawm photosynthesis. Cov kws tshawb fawb tuaj yeem rhuav tshem cov hlwb microalgae thiab tshem tawm cov khoom siv organic xws li roj thiab carbohydrates los ntawm cov hlwb, uas tuaj yeem tsim cov roj huv ntxiv xws li roj bio thiab roj biogas.
Cov pa roj carbon dioxide ntau dhau yog ib qho ua txhaum loj ntawm kev hloov pauv huab cua thoob ntiaj teb. Peb tuaj yeem txo cov pa roj carbon dioxide li cas? Piv txwv li, peb puas tuaj yeem 'noj' nws? Tsis hais, me me microalgae muaj xws li "qab los noj mov zoo", thiab lawv tuaj yeem tsis tsuas yog "noj" carbon dioxide, tab sis kuj hloov mus ua "roj".
Yuav ua li cas kom ua tiav kev siv cov pa roj carbon dioxide tau dhau los ua qhov kev txhawj xeeb tseem ceeb rau cov kws tshawb fawb thoob ntiaj teb, thiab microalgae, cov kab mob me me no, tau dhau los ua tus pab zoo rau peb los kho cov pa roj carbon monoxide thiab txo qis emissions nrog nws lub peev xwm tig "carbon" rau hauv " yog '.

Me microalgae tuaj yeem hloov 'carbon' rau 'roj'
Lub peev xwm ntawm cov microalgae me me los hloov cov pa roj carbon monoxide rau hauv cov roj muaj feem cuam tshuam nrog lawv lub cev. Cov esters thiab suab thaj nplua nuj nyob rau hauv microalgae yog cov khoom siv zoo heev rau kev npaj cov kua roj. Tsav los ntawm lub hnub ci zog, microalgae tuaj yeem tsim cov pa roj carbon dioxide rau hauv siab zog triglycerides, thiab cov roj molecules no tsis tsuas yog siv los tsim biodiesel, tab sis kuj tseem yog cov ntaub ntawv tseem ceeb rau kev rho tawm cov zaub mov tsis txaus fatty acids xws li EPA thiab DHA.
Lub photosynthetic efficiency ntawm microalgae tam sim no yog qhov siab tshaj plaws ntawm tag nrho cov kab mob nyob hauv lub ntiaj teb, 10 txog 50 npaug siab dua li cov nroj tsuag hauv av. Nws tau kwv yees tias microalgae kho txog 90 billion tons ntawm carbon thiab 1380 trillion megajoules ntawm lub zog los ntawm photosynthesis hauv ntiaj teb txhua xyoo, thiab lub zog siv tau yog li 4-5 npaug ntawm lub ntiaj teb kev siv hluav taws xob txhua xyoo, nrog rau cov peev txheej loj.
Nws tau nkag siab tias Tuam Tshoj tso tawm txog 11 billion tons ntawm carbon dioxide txhua xyoo, ntawm ntau tshaj ib nrab yog carbon dioxide los ntawm cov roj hluav taws xob hluav taws xob. Kev siv cov microalgae rau photosynthetic carbon sequestration nyob rau hauv cov chaw lag luam thee raug rho tawm haujlwm tuaj yeem txo qis carbon dioxide emissions. Piv nrog rau cov khoom siv hluav taws xob hluav taws xob ib txwm siv hluav taws xob hluav taws xob hluav taws xob hluav taws xob hluav taws xob txo qis, microalgae carbon sequestration thiab txo cov thev naus laus zis muaj qhov zoo ntawm cov khoom siv txheej txheem yooj yim, kev ua haujlwm yooj yim, thiab kev tiv thaiv ib puag ncig ntsuab. Tsis tas li ntawd, microalgae kuj muaj qhov zoo ntawm kev muaj cov neeg coob coob, yooj yim rau cog, thiab tuaj yeem loj hlob hauv qhov chaw xws li dej hiav txwv, pas dej, saline alkali av, thiab swamps.
Vim tias lawv muaj peev xwm txo qis carbon dioxide emissions thiab tsim lub zog huv si, microalgae tau txais kev saib xyuas thoob plaws hauv tebchaws thiab thoob ntiaj teb.
Txawm li cas los xij, nws tsis yog yooj yim los ua microalgae uas loj hlob dawb hauv cov xwm txheej dhau los ua "cov neeg ua haujlwm zoo" rau cov pa roj carbon sequestration ntawm cov kab lag luam. Yuav ua li cas rau cultivate algae? Qhov microalgae twg muaj cov pa roj carbon sequestration zoo dua? Yuav ua li cas txhim kho cov pa roj carbon sequestration efficiency ntawm microalgae? Cov no yog tag nrho cov teeb meem nyuaj uas cov kws tshawb fawb yuav tsum tau daws.
