Tojsiab
Cov kws tshawb fawb ntawm National Institute of Standards and Technology (NIST) tau hais tias cov khoom hu ua aluminium formate tuaj yeem siv los txhuam cov pa roj carbon dioxide los ntawm cov hluav taws xob hluav taws xob hluav taws xob ua ntej nws mus txog qhov chaw, uas suav txog 30% ntawm tag nrho lub ntiaj teb cov pa roj carbon monoxide emissions, raws li. rau ib qho kev tshawb fawb luam tawm hnub Wednesday nyob rau hauv phau ntawv xov xwm kev tshuaj xyuas cov phooj ywg Kev Txhawb Kev Tshawb Fawb.

Cov Lus Tseem Ceeb
Aluminium formate yog ib feem ntawm cov chav kawm ntawm cov khoom hu ua hlau-organic moj khaum uas tau nthuav tawm lub peev xwm los lim thiab cais cov khoom siv organic, raws li NIST, thiab cov khoom tuaj yeem cais cov pa roj carbon dioxide los ntawm lwm cov gasses uas tau tawm ntawm cov hluav taws xob hluav taws xob. ' smokestacks.
Aluminium formate yog tsim los ntawm aluminium hydroxide thiab formic acid, ob yam tshuaj uas muaj ntau, yooj yim kom tau thiab tsis tshua kim tshaj li cov khoom siv zoo sib xws thiab yuav raug nqi tsawg dua ib duas las ib kilogram, raws li Nist's Hayden Evans, ib tus thawj coj sau ntawv. ntawm cov ntaub ntawv tshawb fawb, uas tau sau tseg hauv a daim ntawv qhia nws yog kwv yees li 100 npaug qis dua li lwm yam khoom siv nrog kev ua haujlwm zoo sib xws.
Nrhiav txoj hauv kev los txo cov nroj tsuag hluav taws xob emissions raws li lub ntiaj teb tshawb nrhiav lwm qhov chaw siv hluav taws xob, xws li cua thiab hnub ci zog, tuaj yeem pab txo cov teebmeem ntawm cov nroj tsuag thee thaum lawv tseem ua haujlwm, raws li Nist.
Txawm li cas los xij, kev siv aluminium formate tuaj yeem xav tau ntau txhiab tons ntawm cov khoom pom kom ntes cov pa roj carbon monoxide ntawm ib tsob nroj, raws li kev tshawb fawb, thiab txawm tias nws muaj peev xwm, aluminium formate tsis npaj rau kev siv tam sim ntawd, cov kws tshawb fawb tau hais.
Cov pa roj carbon monoxide loj yuav xav tau cov txheej txheem tshiab engineering los tsim cov txhuas ntau ntau, raws li daim ntawv, thiab cov chaw tsim hluav taws xob yuav tsum muaj cov txheej txheem sib xws hauv qhov chaw kom txo cov av noo ntawm cov pa ua ntej txhuam.
Evans tau hais tias yuav ua li cas nrog cov khoom siv CO2 tom qab ntawd kuj yog ib qho teeb meem, txawm hais tias kev tshawb fawb tab tom hloov nws mus rau hauv formic acid, ib qho ntawm aluminium formate ob tus neeg sawv cev, hauv dab tsi tuaj yeem dhau los ua cov txheej txheem cyclic, nws hais.
Tus lej Loj
36.3 billion. Qhov ntawd yog pes tsawg tons ntawm carbon dioxide tau raug tso tawm thoob ntiaj teb hauv 2021, raws li International Energy Agency. Nws yog qib siab tshaj plaws uas tau sau tseg thiab sawv cev nce 6% los ntawm xyoo dhau los vim tias kev lag luam hauv ntiaj teb tau rov qab los ntawm Covid-19 kev sib kis qeeb.
Tus Keeb Kwm Tseem Ceeb
Coal-fired fais fab nroj tsuag yog ib qho ntawm cov tsav tsheb tseem ceeb ntawm carbon emissions thiab tsav ze li ntawm ib feem peb ntawm lub ntiaj teb no tsev cog khoom gasses, raws li pab neeg, uas muaj xws li cov kws tshawb fawb los ntawm National University of Singapore, Singapore's Agency for Science, Technology thiab Research, University of Delaware thiab University of California ntawm Santa Barbara. Lub lim tiam dhau los, United Nations tau tshaj tawm txoj kev tshawb fawb uas pom nyob rau hauv cov xwm txheej tam sim no, lub ntiaj teb kub tau npaj rau nce 2.9 degrees Celsius thaum kawg ntawm lub xyoo pua. Daim duab ntawd tau nce siab dua li Paris Climate Agreement lub hom phiaj ntawm kev txwv lub ntiaj teb kub nce mus rau 1.5 degrees Celsius nyob rau tib lub sijhawm. Cov thawj coj tau ceeb toom tias tsis ua raws li lub hom phiaj tuaj yeem ua rau Kev hloov pauv huab cua hnyav heev suav nrog kev kub ntxhov, hluav taws kub hnyiab, nce dej hiav txwv thiab kev tshaib kev nqhis zuj zus. Txij li thaum xyoo 1990s, cov cua sov nthwv dej tau thawb los ntawm kev hloov pauv huab cua tau ua rau kev lag luam thoob ntiaj teb tsawg kawg yog $ 16 trillion, raws li ib tug Kev Txhawb Kev Tshawb Fawb kev tshawb fawb luam tawm lub lim tiam dhau los. Nws muaj feem cuam tshuam rau cov neeg nyob hauv cov teb chaws txom nyem tshaj plaws hauv ntiaj teb no, cov kws tshawb fawb pom.
