A cewar bayanan cibiyar binciken masana'antu,samar da iskar gas hydrogentsari a halin yanzu ya mamaye wuri na farko a kasuwar samar da hydrogen ta duniya. Adadin samar da hydrogen daga iskar gas a kasar Sin ya zo na biyu, bayan haka daga kwal. An fara samar da sinadarin hydrogen daga iskar gas a kasar Sin a cikin shekarun 1970, musamman samar da hydrogen don hada sinadarin ammonia. Tare da haɓaka ingancin mai haɓakawa, kwararar tsari, matakin sarrafawa, nau'in kayan aiki da haɓaka tsari, an tabbatar da amincin da amincin tsarin samar da iskar gas na iskar gas.
Tsarin samar da iskar iskar gas ya ƙunshi matakai huɗu: pretreatment na ɗanyen gas, gyaran tururi na iskar gas, canjin carbon monoxide,hydrogen tsarkakewa.
Mataki na farko shi ne albarkatun kasa pretreatment, wanda yafi nufin danyen gas desulfurization, da ainihin tsari aiki kullum yana amfani da cobalt molybdenum hydrogenation jerin zinc oxide a matsayin desulfurizer don maida Organic sulfur a cikin halitta gas zuwa inorganic sulfur sa'an nan kuma cire shi.
Mataki na biyu shi ne gyaran tururi na iskar gas, wanda ke amfani da sinadarin nickel a cikin mai kawo gyara don mayar da alkanes da ke cikin iskar gas zuwa iskar abinci mai gina jiki wanda manyan abubuwan da suka hada da carbon monoxide da hydrogen.
Mataki na uku shine motsi carbon monoxide. Yana amsawa da tururin ruwa a gaban mai kara kuzari, ta haka ne ke samar da hydrogen da carbon dioxide, da samun iskar gas mai motsi wanda galibi ya hada da hydrogen da carbon dioxide.
Mataki na ƙarshe shine tsarkake hydrogen, yanzu tsarin tsarkakewar hydrogen da aka fi amfani dashi shine tsarin rabuwar tsarkakewa (PSA). Wannan tsarin yana da halaye na ƙarancin amfani da makamashi, tsari mai sauƙi da babban tsabta na hydrogen.
Samar da sinadarin hydrogen daga iskar gas yana da fa'ida daga babban sikelin samar da hydrogen da balagaggen fasaha, kuma shine babban tushen hydrogen a halin yanzu. Duk da cewa iskar iskar gas ma burbushin man fetur ne kuma yana samar da iskar gas wajen samar da sinadarin hydrogen mai launin shudi, amma saboda amfani da fasahar zamani kamar kama carbon, utilization da Storage (CCUS), ya rage tasirin muhallin duniya ta hanyar kamawa. iskar gas da kuma cimma ƙarancin fitarwa.
