Deng talapanaliksik keng Chung-Ang University keng South Korea mika idea lang gamitan ing industrial carbon dioxide ampo dolomite, metung a karaniwan ampo laganap a sedimentary rock a dakal a calcium ampo magnesium, para makagawa lang adwang komersyal a produktu: calcium formate ampo magnesium oxide.
King metung a papel a mibulalag keng Journal of Chemical Engineering, pepaliwanag da reng siyentipiku na ing karelang carbon capture and utilization (CCU) technology makabasi ya keng prosesu na magsamut kareng carbon dioxide hydrogenation reactions ampo cation exchange reactions para sabay-sabay lang malinis deng metal oxides ampo makagawa lang high-value, high-value formate. Panagandaman.
Partikular, ginamit lang catalyst (Ru/bpyTN-30-CTF) para dagdagan ing hydrogen keng carbon dioxide, at mika adwang value-added a produktu. Ing leather tanning gagamit ya namang calcium formate, cement additives, deicers ampo animal feed additives. Ing magnesium oxide, keng aliwang banda, maralas yang magagamit keng construction ampo keng industriya ning parmasyutika.
Deng manimunang talapanaliksik a di Seongho Yoo ampo i Chul-Jin Lee sasabyan da na ing prosesu ali ya mu malyari, nune mabilis ya, at gagawan ne ing produktu kilub ning limang minutu keng temperatura ning silid. Dagdag pa, ing kayang grupu sasabyan na ing prosesu malyari yang mabawas ing global warming potential keng 20% ​​kumpara kareng tradisyunal a paralan ning pamaglalang calcium formate.
Ing grupu sinuri na nung ing karelang paralan malyari yang palitan ing kasalukuyan nang paralan ning pamaglalang kapamilatan ning pamagsuri king kayang epektu king kapaligiran at king kayang panga-ekonomiya.
"Base kareng resulta, asabi mi na ing kekaming paralan metung yang environmentally friendly a alternatibung paralan para keng pamagbayu ning carbon dioxide na malyaring palitan ing tradisyunal a paralan at makasaup para mabawas ing industrial carbon dioxide emissions," sinabi nang Yun.
Ing scientist sinabi na kabang ing pamagbayu keng carbon dioxide para maging kapakibatan a produktu balamu promising ya, deng prosesung deni ali la parating madaling i-scale. keraklan kareng teknolohiya ning CCU e la pa me-commercialize uling mababa ing karelang economic feasibility kumpara kareng mainstream a prosesung pang-komersiyu.
"Kailangan tamung isamut ing prosesu ning CCU keng pamag-recycle ning basura para maging viable ya keng kapaligiran ampo keng ekonomiya. Iti makasaup para akwa ing net-zero emissions targets keng daratang a panaun," sinabi nang Lee.
