Chiyembekezo Chatsopano cha Tsogolo Lobiriwira — Furan Dicarboxylic Acid

Pa nthawi imene dziko lapansi likuchita zinthu molimbika pa nkhani ya chitukuko chokhazikika komanso kuyesetsa kukwaniritsa zolinga za "dual carbon", furandiformic acid (FDCA) yakhala nyenyezi yatsopano yodabwitsa pankhani ya zinthu zopangidwa ndi zamoyo, zomwe zatitsegulira khomo latsopano la tsogolo lobiriwira.

Furanediformic acid, monga cholimba choyera, imasungunuka m'madzi ndi zinthu zina zachilengedwe monga ma alcohols ndi ma esters. Imakhala ndi mphamvu yowola, mphamvu yogwira ntchito komanso kukhazikika kwabwino kwa mankhwala. Sikuti ndi mankhwala ofunikira okha ochokera ku bio, komanso ndi amodzi mwa mayunitsi ofunikira kwambiri pakupanga zinthu zapamwamba komanso zinthu za polima zomwe zimawonjezera phindu. Kuchita bwino kwake kwapadera m'magawo ambiri ofunikira nthawi zonse kumalembanso kapangidwe ka makampani ndikubweretsa mwayi ndi kusintha kosayembekezereka m'magawo ambiri.

Kuchokera pakuwona kuteteza chilengedwe, furanediformic acid ili ndi ubwino wosayerekezeka. Kupanga polyester yachikhalidwe kumadalira kwambiri zinthu zopangira petrochemical, monga terephthalic acid (PTA). Njira yonse yopangira sikuti imangogwiritsa ntchito mafuta ambiri osabwezeretsedwanso komanso imatulutsa mpweya wambiri wa kaboni, zomwe zimapangitsa kuti chilengedwe chikhale cholemera kwambiri. Kubadwa kwa furanediformic acid kunathetsa vutoli. Imagwiritsa ntchito biomass yobwezerezedwanso ngati zinthu zopangira, kuchepetsa kudalira mafuta ochokera ku gwero ndikuchepetsa kwambiri mpweya wa kaboni. Malinga ndi ziwerengero za akatswiri, zinthu za polyethylene glycol 2, 5-furanediforme (PEF) zopangidwa kuchokera ku furanediforme acid zimatha kuchepetsa kwambiri "carbon footprint" m'moyo wawo wonse poyerekeza ndi zinthu zachikhalidwe za PET, zomwe zimapangitsa kuti pakhale chitukuko chobiriwira komanso chokhazikika cha Dziko Lapansi. Khalidweli limapangitsa furandiformic acid kukhala chinthu chomwe chimakondedwa ndi mabizinesi ambiri pakufunafuna kusintha kwa chitetezo cha chilengedwe, ndikulimbikitsa bwino kusintha kwakuya kwa mafakitale osiyanasiyana kukhala mitundu yopanga zobiriwira. Ponena za magwiridwe antchito, furanediformic acid nayonso ndi yodabwitsa. Ili ndi kapangidwe ka molekyulu kofanana ndi ka monomer terephthalic acid (PTA) yachikhalidwe yochokera ku petroleum, yonse yokhala ndi fungo labwino la dongosolo lozungulira lolumikizidwa ndipo yonse ili ndi magulu awiri a hydroxyl, zomwe zimapangitsa kuti ikhale yofanana kwambiri m'thupi komanso m'mankhwala. Komabe, mphete ya furan ya furanediformic acid ndi kapangidwe ka heterocyclic, ndipo kapangidwe kake kapadera kameneka kamapereka mawonekedwe osavuta kuwonongeka kuposa mphete ya benzene. Pakadali pano, kudzera mu polymerization reactions ndi ma monomers monga diols ndi diamines, furanediformic acid ingagwiritsidwe ntchito kukonza polyester yapamwamba, polyamide ndi zinthu zina zatsopano zopangidwa ndi polymer zomwe zili ndi mankhwala a aromatic. Tengani zinthu za PEF mwachitsanzo. Makhalidwe ake otchinga motsutsana ndi mpweya wosiyanasiyana ndi amphamvu kwambiri kuposa a zinthu zachikhalidwe za PET. Nthawi yomweyo, ili ndi mphamvu zambiri zamakaniko ndipo imatha kupanga zinthu zopaka zokhala ndi makulidwe owonda a khoma. Izi sizimangowonjezera magwiridwe antchito a chinthucho, komanso zimachepetsa bwino kugwiritsa ntchito zinthu zopaka, kukwaniritsa zolinga ziwiri zowongolera magwiridwe antchito komanso kusunga chuma. Magawo ambiri ogwiritsira ntchito a furanediformic acid akuwonetsanso kufunika kwake pamsika. Pankhani ya zinthu zopakira, zinthu za PEF, zomwe zimakhala ndi mphamvu zabwino kwambiri zotchingira mpweya komanso mphamvu ya makina, zimatha kuteteza bwino zomwe zili mu chakudya, mankhwala, ndi zina zotero, kukulitsa nthawi yawo yosungira, komanso kuchepetsa kupanga zinyalala zopakira, zomwe zimapangitsa kuti makampani opanga zinthu zobiriwira azigwira ntchito bwino. Pankhani ya ulusi wa nsalu, zinthu zopangidwa ndi ulusi wochokera ku furanediformic acid zimakhala ndi mphamvu zambiri, modulus yambiri komanso kukana dzimbiri kwa mankhwala. Zitha kugwiritsidwa ntchito kwambiri pazinthu zapamwamba komanso m'magawo apadera monga mafakitale ndi chitetezo cha dziko, zomwe zimawonjezera kwambiri ubwino ndi magwiridwe antchito a zinthuzo. Kuphatikiza apo, furanediformic acid yawonetsa mwayi waukulu wogwiritsidwa ntchito m'magawo ambiri monga ma CD a mankhwala, mapulasitiki aukadaulo, nayiloni, zokutira, ndi mapulasitiki, ndipo pang'onopang'ono ikukhala mphamvu yayikulu yopititsa patsogolo ukadaulo ndi kupanga zinthu zatsopano m'mafakitale osiyanasiyana.

Chifukwa cha kuwonjezeka kosalekeza kwa chidwi cha dziko lonse pa chitukuko chokhazikika komanso kufunikira kwakukulu kwa zinthu zopangidwa ndi zamoyo, mwayi wamsika wa furandiformic acid ndi wowala kwambiri. Malinga ndi zomwe mabungwe odalirika adaneneratu, pofika chaka cha 2027, kukula kwa msika wa FDCA kukuyembekezeka kupitirira matani miliyoni imodzi, ndi kuthekera kwakukulu kwa msika. Pakadali pano, mabizinesi ambiri odziwika bwino akuyika mwachangu makampani opanga furanediformic acid, ndikuwonjezera ndalama mu kafukufuku ndi chitukuko komanso kulimbikitsa luso. Mwachitsanzo, monga kampani yotsogola padziko lonse lapansi ya zinthu zopangidwa ndi zamoyo, Lifu Bio, pambuyo pa zaka zoposa khumi za kafukufuku ndi chitukuko chosalekeza, yafufuza bwino njira yapadera yapadziko lonse ya "Biomass glucose HMF FDCA", kusiya kudalira zinthu zopangidwa ndi zamoyo zopangidwa ndi furan pa fructose yochokera ku tirigu. Mu 2022, idayambitsa bwino mzere woyamba wa FDCA padziko lonse wa matani 1,000, ndipo mu Seputembala 2024, idayambitsa kumanga mzere woyamba wa FDCA padziko lonse wa matani 10,000. Ndi kukula kwa kukula ndi kupititsa patsogolo khalidwe, ikutsogolera chitukuko cha makampani opanga zinthu zachilengedwe a furan. Pakadali pano, gulu lochokera ku East China University of Science and Technology likuchitanso kafukufuku wokhudza pulojekiti ya "Kusintha kwa Biomass kukhala Plastic Monomer - Furanediformic acid". Mwa kupanga zinthu zatsopano komanso njira zopangira zinthu mosalekeza, akhazikitsa njira yopangira zinthu mosalekeza kuchokera ku shuga kupita ku 2, 5-furanediformic acid, zomwe zikulimbikitsa bwino kupita patsogolo kwa ukadaulo wa furanediformic acid komanso chitukuko cha makampaniwa.

Furandiformic acid, monga chinthu chodziwika bwino pakupanga zinthu zopangidwa ndi zamoyo, ikutsogolera mafakitale osiyanasiyana ku nthawi yatsopano ya chitukuko chobiriwira komanso chokhazikika ndi magwiridwe antchito ake abwino kwambiri oteteza chilengedwe, mawonekedwe ake abwino kwambiri a thupi ndi mankhwala, komanso mwayi wogwiritsidwa ntchito kwambiri. Sikuti imapatsa mabizinesi mwayi wabwino kwambiri wokwaniritsa kusintha kwa chitetezo cha chilengedwe ndikusintha zinthu, komanso imatipatsa maziko olimba kuti titeteze dziko lathu lapansi ndikupanga tsogolo lowala. Tiyeni tigwirizane ndikulandira furanediformic acid, chiyembekezo chatsopanochi cha tsogolo lobiriwira, ndi chidwi, ndikupanga tsogolo lobiriwira komanso lopambana!
