Ngokusho kwedatha yesikhungo socwaningo lwemboni,ukukhiqizwa kwe-hydrogen yegesi yemveloinqubo njengamanje ithatha indawo yokuqala emakethe yomhlaba yokukhiqiza i-hydrogen. Ingxenye yokukhiqizwa kwe-hydrogen ngegesi yemvelo eChina isendaweni yesibili, ngemva kwalokho isuka emalahleni. Ukukhiqizwa kwe-hydrogen ngegesi yemvelo e-China kwaqala ngawo-1970, ikakhulukazi ukuhlinzeka nge-hydrogen yokuhlanganiswa kwe-ammonia. Ngokuthuthukiswa kwekhwalithi ye-catalyst, ukugeleza kwenqubo, izinga lokulawula, ifomu lemishini kanye nokwenza kahle kwesakhiwo, ukuthembeka nokuphepha kwenqubo yokukhiqiza igesi yemvelo i-hydrogen kuqinisekisiwe.
Inqubo yokukhiqiza igesi yemvelo ye-hydrogen ikakhulukazi ihlanganisa izinyathelo ezine: igesi eluhlaza, ukuguqulwa kwesitimu segesi yemvelo, ukushintsha kwe-carbon monoxide,ukuhlanza i-hydrogen.
Isinyathelo sokuqala i-pretreatment yempahla eluhlaza, okubhekiselwa kuyo ikakhulukazi ekuqothulweni kwegesi eluhlaza, inqubo yangempela yokusebenza ngokuvamile isebenzisa uchungechunge lwe-cobalt molybdenum hydrogenation zinc oxide njenge-desulfurizer ukuguqula isulfure ephilayo kugesi yemvelo ibe yisulfure ye-inorganic bese isusa.
Isinyathelo sesibili ukuguqulwa kwesitimu segesi yemvelo, esebenzisa i-nickel catalyst ku-reformer ukuguqula ama-alkanes kugesi yemvelo ibe igesi ye-feedstock izingxenye zayo eziyinhloko okuyi-carbon monoxide ne-hydrogen.
Isinyathelo sesithathu i-carbon monoxide shift. Ihlangana nomhwamuko phambi kwe-catalyst, ngaleyo ndlela ikhiqize i-hydrogen ne-carbon dioxide, futhi ithole i-shift gas eyakhiwe ikakhulukazi i-hydrogen ne-carbon dioxide.
Isinyathelo sokugcina ukuhlanza i-hydrogen, manje uhlelo lokuhlanza i-hydrogen olusetshenziswa kakhulu uhlelo lokuhlukanisa i-press swing adsorption (PSA). Lolu hlelo lunezici zokusebenzisa amandla aphansi, inqubo elula kanye nokuhlanzeka okuphezulu kwe-hydrogen.
Ukukhiqizwa kwe-hydrogen ngegesi yemvelo kunezinzuzo zesikali esikhulu sokukhiqiza i-hydrogen nobuchwepheshe obuvuthiwe, futhi kuwumthombo oyinhloko we-hydrogen okwamanje. Nakuba igesi yemvelo iphinde ibe uphethiloli wezinto ezimbiwa phansi futhi ikhiqiza amagesi abamba ukushisa lapho kukhiqizwa i-blue hydrogen, kodwa ngenxa yokusetshenziswa kobuchwepheshe obuthuthukisiwe obufana ne-carbon capture, utilization and Storage (CCUS), inciphise umthelela endaweni ezungezile yoMhlaba ngokubamba. amagesi abamba ukushisa kanye nokuzuza ukukhiqizwa kokukhishwa okuncane.
