University of Toyama, Chiyoda Corporation, Nippon Steel Engineering Co, Nippon Steel Corporation, tuam txhab HighChem, thiab Mitsubishi Corporation tau raug xaiv los ua tus tuav txoj haujlwm rau ib txoj haujlwm los tsim technology rau para-xylene ntau lawm los ntawm cov pa roj carbon dioxide. Para-xylene yog cov khoom siv raw, tam sim no tau los ntawm petrochemicals, rau cov xov paj hluavtaws.
Cov pab pawg yuav txhim kho lub tswv yim tshiab rau kev tsim cov khoom siv para-xylene los ntawm cov pa roj carbon dioxide, txhim kho txoj hauv kev los tsim cov khoom tsim tawm catalyst, thiab tsim cov txheej txheem thaum kawm txog nws cov kev ua lag luam nrog rau nws qhov kev khwv nyiaj txiag tag nrho thiab cov pa roj carbon dioxide txo cov nyhuv kom cog lus txoj kev mus rau theem ua qauv qhia.
Txhawm rau tiv thaiv lub ntiaj teb kev hloov pauv huab cua, nws yog qhov tsim nyog los hais txog qhov teeb meem ntawm cov pa roj carbon dioxide los ntawm cov chaw ua haujlwm, cov chaw tsim hluav taws xob, thiab ntau yam kev tso pa tawm thaum mus nrhiav txhua qhov kev siv thev naus laus zis nrog rau cov khoom siv thev naus laus zis.
Lub tswv yim" Txoj Kev Tawm rau Kev Tsim Kho Kev Siv Carbon" tsim los ntawm METI (Ministry of Economic, Kev Lag Luam thiab Kev Lag Luam) thaum Lub Rau Hli 2019 teeb tsa cov txheej txheem rau kev siv cov khoom siv thev naus laus zis rau kev sib cais thiab khaws cov roj carbon dioxide ua cov khoom siv thiab rov siv nws cov khoom siv roj carbon ntau rau cov khoom siv tshuaj lossis roj av.
Tawm tsam cov thim rov qab no, NEDO (Lub Koom Haum Saib Xyuas Kev Tsim Kho Tshiab thiab Kev Tsim Kho Kev Tsim Kho Tshiab) tau tsim ib txoj haujlwm kev tsim kho rau lub ntiaj teb' s feem ntau cov thev naus laus zis rau kev lag luam para-xylene ntau lawm los ntawm cov pa roj carbon dioxide los hloov cov roj av uas tau muaj los ua cov tshuaj, thiab cov pab pawg tau raug xaiv los ua haujlwm ua tiav rau qhov haujlwm tau cog lus tseg no.
Para-xylene yog qhov tseem ceeb tshaj yog qhov tseem ceeb hauv kev tsim PTA uas yog cov khoom siv pub rau cov polyesters xws li polyester fibers thiab lub hwj yas. Vim nws cov ntawv muaj pes tsawg leeg, nws tuaj yeem tsim tawm nrog cov pa ntawm hydrogen thaum kho cov pa roj carbon dioxide ntau, piv rau lwm cov tebchaw los ntawm cov roj carbon dej rov ua dua tshiab. Nov yog lub ntsiab lus uas muaj peev xwm ntau los ntawm kev pom ntawm kev lag luam thiab ib puag ncig.
Qhov kev thov thoob ntiaj teb rau para-xylene yog kwv yees li 49 lab tons hauv ib xyoos. Piv txwv tias kev pub khoom noj rau para-xylene ntawm qib qhov xav tau tam sim no yog hloov tag nrho los ntawm fossil fuels mus rau carbon dioxide, raws li 160 lab tons ntawm carbon dioxide tuaj yeem kho nyob hauv para-xylene ib xyoos twg.
