Abarhubhululi be-Chung-Ang University e-South Korea bafika nomqondo wokusebenzisa i-carbon dioxide yezebubulo ne-dolomite, idwala elivamileko nelisakazekako eline-calcium ne-magnesium, ukukhiqiza imikhiqizo emibili ezokuthengisa: i-calcium formate ne-magnesium oxide.
Ephepheni eligadangiswe ku-Jenali ye-Chemical Engineering, abososayensi bahlathulula bona ithekhnoloji yabo yokubamba nokusebenzisa i-carbon (i-CCU) isekelwe enkambisweni ehlanganisa ukusabela kwe-carbon dioxide hydrogenation kanye nokusabela kokutjhentjhana kwe-cation ukuhlanza ama-metal oxides ngasikhathi sinye begodu kukhiqize i-formate enani eliphezulu, inani eliphezulu. umkhiqizo.
Ngokukhethekileko, basebenzisa i-catalyst (Ru/bpyTN-30-CTF) ukufaka i-hydrogen ku-carbon dioxide, ukukhiqiza imikhiqizo emibili enenani elingezelelweko. Ukutjhugulula isikhumba godu kusebenzisa i-calcium formate, izengezo zesamente, ama-deicers kanye nezengezo zokudla kweenlwana. I-magnesium oxide, ngakelinye ihlangothi, isetjenziswa khulu emabubulweni wokwakha nemithi.
Abarhubhululi abadosa phambili u-Seongho Yoo no-Chul-Jin Lee bathi ikambiso le ayikghonakali kwaphela, kodwana irhaba khulu, ikhiqiza umkhiqizo ngemizuzu emihlanu kwaphela emazingeni womtjhiso wegumbi. Ukungezelela, isiqhema sakhe silinganisela bona ikambiso le ingehlisa ukufuthumala kwephasi ngama-20% nayiqathaniswa neendlela zesiko zokukhiqiza i-calcium formate.
Isiqhema sibuye sahlolisisa bona indlela yabo ingathatha indawo yeendlela zokukhiqiza ezikhona ngokuhlola umthelela wayo ebhodulukweni nokuphumelela kwezomnotho.
"Ngokuya ngemiphumela, singatjho bona indlela yethu yindlela engalimazi ibhoduluko yokutjhugulula i-carbon dioxide engathatha indawo yeendlela ezijayelekileko begodu isize ukwehlisa ukukhutjhwa kwe-carbon dioxide emabubulweni," kutsho u-Yun.
Usosayensi watjheja bona ngitjho nanyana ukutjhugulula i-carbon dioxide ibe mikhiqizo ewusizo kuzwakala kuthembisa, iinkambo lezi akulula ngaso soke isikhathi ukuzikhulisa. Inengi lamathekhnoloji we-CCU alikathengiswa ngombana ukusebenza kwawo kwezomnotho kuphasi nayiqathaniswa neenkambo ezijayelekileko zokuthengisa.
"Kutlhogeka bona sihlanganise ikambiso ye-CCU nokubuyiselwa kwemfucuza ukwenzela bona ibe yinto ephumelelako emvelweni nezomnotho. Lokhu kungasiza ukufikelela imigomo yokukhipha i-net-zero esikhathini esizako," kutsho u-Lee.
