Kupanga haidrojeni ndi mpweya wachilengedwe Ili ndi ubwino wotsika mtengo komanso mphamvu zake zazikulu. Kafukufuku ndi chitukuko cha ukadaulo watsopano wapamwamba kwambiri wopanga haidrojeni kuchokera ku gasi wachilengedwe ndi chitsimikizo chofunikira chothetsa vuto la gwero lotsika mtengo la haidrojeni. Monga mphamvu yapamwamba komanso yoyera yamafakitale, gasi wachilengedwe uli ndi zinthu zofunika kwambiri popanga mphamvu ku China. Nthawi yomweyo, ndi chinthu chofunikira kwambiri pazinthu zambiri zamankhwala.
Monga mankhwala achiwiri, haidrojeni imagwiritsidwa ntchito kwambiri m'mafakitale opanga mankhwala, mankhwala abwino, zamagetsi ndi zamagetsi. Makamaka, haidrojeni, monga mafuta ofunikira kwambiri a maselo amafuta, idzakhala ndi mwayi waukulu pamsika woyendera ndi kupanga magetsi mtsogolo ndipo idzakhala ndi malo ofunikira kwambiri mu kapangidwe ka mphamvu mtsogolo. Njira zachikhalidwe zopangira haidrojeni, monga kusintha kwa nthunzi ya hydrocarbon, electrolysis yamadzi, kusweka kwa methanol, kuyika gasi m'malasha ndi kuwonongeka kwa ammonia, ndizokhwima pang'ono. Komabe, pali mavuto ena, monga mtengo wokwera, kuchuluka kochepa kwa zotulutsa, kugwira ntchito kochepa, limodzi lokwera ndi awiri otsika. Pakupanga mafuta ndi gasi ku Liaohe Oilfield, pali zinthu zama hydrocarbon monga mpweya wouma ndi naphtha. Kupanga haidrojeni pogwiritsa ntchito njira iyi kungapangitse kuti zinthu zigwiritsidwe ntchito kwambiri. Kuphatikiza apo, gawo lalikulu la mpweya wachilengedwe wogwirizana ndi methane, womwe ungasinthidwe kukhala haidrojeni ndi nthunzi ya hydrocarbon, wokhala ndi kuyera kwakukulu kopanga komanso magwiridwe antchito apamwamba.
Njira zazikulu zopangira mpweya wachilengedwe zimaphatikizapo kusungunuka kwa mpweya mumlengalenga ndi vacuum, kusweka kwa catalytic, kusintha kwa catalytic ndi kupanga aromatics. Nthawi yomweyo, kuphatikizapo kugwiritsa ntchito gasi wachilengedwe, kusonkhanitsa ndi kuyeretsa, alkanes ndi nthunzi mu mpweya wachilengedwe zimachita mankhwala pansi pa kupanikizika kwina, kutentha kwambiri, ndi catalyst.
Pambuyo posinthana kutentha mu boiler yolipira, mpweya wosinthidwa umalowa mu uvuni wosinthira kuti usinthe Co kukhala H2 ndi CO2. Kenako, pambuyo posinthana kutentha, kuzizira ndi kulekanitsa madzi a nthunzi, mpweyawo umadutsa motsatizana kudzera mu nsanja yotsatsira yokhala ndi ma adsorbents atatu apadera kudzera mu pulogalamu yowongolera, ndipo N2 co CH4 CO2 imapanikizika ndikutsanulidwa ndi pressure swing adsorption (PSA) kuti ichotse haidrojeni ya chinthu, kuchepetsa kupsinjika ndikusanthula kuti itulutse zinyalala ndikubwezeretsanso adsorbent.
