Ofufuza a ku Germany anena m'magazini yaposachedwa ya nyuzipepala yaku UK Nature kuti apanga njira yatsopano yosungunulira aloyi yomwe imatha kusintha ma oxides olimba achitsulo kukhala ma aloyi owoneka ngati chipika mu sitepe imodzi. Ukadaulowu sumafuna kusungunuka ndi kusakaniza zitsulo zitachotsedwa, zomwe zimathandiza kuchepetsa mpweya wowonjezera kutentha ndikusunga mphamvu.

Ofufuza a Max Planck Institute for Sustainable Materials ku Germany adagwiritsa ntchito haidrojeni m'malo mwa carbon monga chochepetsera kuchotsa zitsulo ndi kupanga aloyi pa kutentha kwambiri pansi pa malo osungunuka achitsulo, ndipo apanga bwino ma alloys owonjezera otsika poyesera. Ma alloys otsika otsika amapangidwa ndi 64% chitsulo ndi 36% nickel, ndipo amatha kusunga voliyumu yawo mkati mwa kutentha kwakukulu, kuwapangitsa kuti azigwiritsidwa ntchito kwambiri m'makampani.

Ofufuzawo anasakaniza ma oxides a chitsulo ndi faifi tambala mumgawo wofunikira wa ma aloyi okulirapo pang’ono, kuwapera mofanana ndi mphero ya mpira ndi kukanikiziramo makeke ang’onoang’ono ozungulira. Kenako anawotcha makekewo mu ng’anjo kufika madigiri 700 Celsius ndipo anabweretsa hydrogen. Kutentha sikunali kokwanira kusungunula chitsulo kapena faifi tambala, koma kunali kokwanira kuti chitsulocho chichepetse. Mayesero adawonetsa kuti chitsulo chopangidwa ndi chipikacho chinali ndi mawonekedwe a ma alloys ocheperako komanso anali ndi makina abwinoko chifukwa cha kukula kwake kochepa. Chifukwa chomalizidwacho chinali ngati chipika m'malo mwa ufa kapena nanoparticles, zinali zosavuta kuponya ndi kukonza.

Traditional aloyi smelting kumafuna njira zitatu: choyamba, zitsulo oxides mu ore yafupika zitsulo ndi carbon, ndiye zitsulo decarbonized ndi zitsulo zosiyanasiyana amasungunuka ndi kusakaniza, ndipo potsiriza, matenthedwe-mawotchi processing ikuchitika kusintha microstructure wa aloyi kuti apereke zinthu zenizeni. Masitepewa amawononga mphamvu zambiri, ndipo njira yogwiritsira ntchito mpweya wochepetsera zitsulo imapanga mpweya wambiri wa carbon dioxide. Mpweya wa kaboni wochokera kumakampani azitsulo umapangitsa pafupifupi 10% ya dziko lonse lapansi.

Ofufuzawo adanena kuti njira yogwiritsira ntchito haidrojeni kuchepetsa zitsulo ndi madzi, opanda mpweya wa carbon, komanso kuti njira yosavutayi ili ndi mwayi waukulu wopulumutsa mphamvu. Komabe, zoyesererazo zidagwiritsa ntchito ma oxides achitsulo ndi faifi tambala wachiyero chapamwamba, komanso magwiridwe antchito
