Kubudirira muTekinoroji yeGreen Solvent: Zvishandiso zviviri zveBio-Based uye denderedzwa Solutions

1.Eastman Yatanga Ethyl Acetate "Circular Solution," Yakanangana ne30% yeChigadzirwa Chinobva kuRenewable Carbon panosvika 2027

Musi wa20 Mbudzi, 2025, Eastman Chemical yakazivisa shanduko huru yehurongwa: kubatanidza bhizinesi rayo repasi rose re ethyl acetate muchikamu chayo che "Circular Solutions", ichitarisa pakusimudzira modhi yekugadzira yakavharwa ichishandisa ethanol yakagadzirwa nebio sezvinhu zvakagadziriswa. Kambani iyi yakagadzira nzvimbo dzekudzoreredza nekudzoreredza solvent muNorth America neEurope panguva imwe chete, ichivavarira kuwana zvinopfuura 30% yezvigadzirwa zvayo zve ethyl acetate kubva kuzvinhu zvinogadziriswazve kabhoni panosvika 2027. Iyi nzira itsva inoderedza kuburitswa kwekabhoni kubva mukugadzirwa kwesolvent ne42% uku ichichengetedza zviyero zvekushanda zvakaenzana nezvigadzirwa zvechinyakare.

Kufambira mberi uku kunoenderana nemafambiro makuru eindasitiri, sezvinoonekwa muzvirongwa zvakaita sechirongwa chekuchenesa solvent chakatangwa pamwe chete nePPG neSAIC General Motors, icho chakarongerwa kuderedza kuburitswa kweCO₂ nematani 430 pagore. Kuedza kwakadaro kunosimbisa mafambiro ekuchinja muchikamu chemakemikari, uko kuchengetedzeka kuri kuwedzera kutungamirirwa neinjini mbiri dzezvikafu zvebio-based uye masisitimu epamusoro edenderedzwa. Nekuisa pamberi zviwanikwa zvinodzokororwa uye kudzokororwa zvinobudirira, izvi zvitsva hazvingoderedzi kukanganisa kwezvakatipoteredza chete asiwo zvinosimudzira kushanda zvakanaka kwezviwanikwa, zvichiisa chiyero chitsva chekugadzira zvakasvibira muindasitiri. Kubatana kwezvinhu zvinogadzirwa nebio-based uye nzira dzakatenderera kunomiririra nzira yakazara yekubvisa kabhoni mumagadzirirwo ekugadzira, zvichigadzira nzira yeramangwana remaindasitiri rinogara kwenguva refu uye rakasimba.

2.PPG neSAIC-GM Vatanga Zviri Pamutemo Chirongwa Chekudzokorodza Zvinwiwa muSuzhou musi wa1 Gumiguru, 2025

Musi wa1 Gumiguru, 2025, mutungamiri wekambani yezvokupfeka zvemotokari PPG, pamwe chete neSAIC General Motors, vakatanga zviri pamutemo chirongwa chekutanga chekugadzirisazve zvinonyungudutsa muSuzhou. Chirongwa ichi chinoumba sisitimu yakazara, yakavharwa inosanganisira hupenyu hwese hwezvinonyungudutsa: kubva pakugadzirwa nekushandiswa kusvika pakudzoreredza kwakanangwa, kuvandudzwa kwezviwanikwa, uye kushandiswazve. Vachishandisa tekinoroji yepamusoro yekunyungudutsa, maitiro aya anoburitsa zvinobudirira zvikamu zvakachena kubva muzvinonyungudutsa zvakaraswa.

Chirongwa ichi chakagadzirirwa kuunganidza matani anopfuura mazana mana nemakumi matatu emarara gore rega rega, zvichireva kuti huwandu hwekushandisazve hunosvika makumi masere muzana (80%) hunoratidza kuti chirongwa ichi chichaderedza kuburitswa kwecarbon dioxide nematani angangoita mazana mana nemakumi matatu pagore, zvichideredza zvakanyanya kukanganiswa kwemabasa ekugadzira mota. Nekushandura marara kuita zviwanikwa zvinokosha, kubatana uku kunoisa chiyero chitsva chegirini yeindasitiri, zvichiratidza muenzaniso wehupfumi hwakatenderera uye kugadzira zvinhu zvinogara kwenguva refu.

3Masayendisiti ekuChina abudirira muindasitiri yeGreen Ionic Liquid Solvents ne99% Recovery Rate.

Musi wa18 Chikumi 2025, chirongwa chekutanga chepasi rose che ionic liquid-based regenerated cellulose fiber chakatanga kushanda muXinxiang, Henan. Yakagadzirwa nechikwata chekutsvagisa chinotungamirwa naAcademician Zhang Suojiang, tekinoroji iyi itsva inotsiva maacids, alkalis, uye carbon disulfide anoshandiswa mumaitiro echinyakare eviscose neisina kugadzikana uye yakagadzikana yeionic liquids. Sisitimu itsva iyi inoita kuti mvura yakasviba, gasi rakasviba, uye marara akasimba zvibude kusvika zero, ukuwo ichiratidza mwero wekudzoreredza solvent unodarika 99%. Tani yega yega yechigadzirwa inoderedza kuburitswa kwecarbon dioxide nematani angangoita 5,000.

Zvatove zvichishandiswa muzvikamu zvakaita sezvehutano uye machira, budiriro iyi inopa nzira inochengetedza kushanduka kwezvakatipoteredza kweindasitiri yefiber yemakemikari, zvichiisa chiyero chekushandiswa kwezvinonyungudutsa zvine hushamwari kune nharaunda padanho remaindasitiri.
