Isici esivelele kakhulu se-adiabatic ukuguqulwa kwegesi yemvelo ibe yi-hydrogenukuthi iningi lezinto eziluhlaza empeleni ziyizindlela zokuxoxisana ezingaphelele, futhi isinyathelo sokulawula isivinini sesibe yindlela yokuxoxisana engaphelele esheshayo, ethuthukisa kakhulu amandla okukhiqiza iyunithi yokukhiqiza i-hydrogen yegesi yemvelo. Inqubo yokukhiqiza i-hydrogen yokuguqulwa kwegesi yemvelo esebenzisa umoya oshibhile njengomthombo we-oxygen. I-reactor eklanyelwe equkethe i-oxygen distributor ingaxazulula inkinga ye-hot spot ye-catalyst bed kanye nokusatshalaliswa kwamandla okunengqondo. Ukuqina kokusabela kwezinto ezixoxisanayo kuthuthukiswa kakhulu ngenxa yokuncipha kwe-hot spot embhedeni. Ukukhiqizwa kwe-hydrogen encane endaweni ye-hydrogen yokuguqulwa kwegesi yemvelo ukukhiqizwa kwe-hydrogen ye-adiabatic esiteshini se-hydrogenation kungabonisa kangcono amandla ayo okukhiqiza aqinile. Inqubo entsha inezinzuzo zenqubo emfushane kanye neyunithi yokusebenza elula, futhi inganciphisa kakhulu izindleko zokutshalwa kwezimali kanye nokukhiqizwa kwe-hydrogen yeyunithi yokukhiqiza i-hydrogen encane endaweni ye-small.
Ukushiswa okungaphelele kwegesi yemvelo ibe yi-hydrogen. Uma kuqhathaniswa nendlela yendabuko yokuguqula umusi, ukushiswa okungaphelele kwegesi yemvelo ibe yi-syngas kudla amandla amancane futhi kusebenzisa ukujiya okushibhile kakhulu ukuhlanganisa i-reactor. Kodwa-ke, ukushiswa okungaphelele kwegesi yemvelo ibe yi-hydrogen kwandisa ukutshalwa kwezimali okubizayo kanye nezindleko zokukhiqizwa kwe-oxygen yeyunithi yokuhlukanisa umoya ngenxa yenani elikhulu le-oxygen emsulwa. I-membrane ye-ceramic oxygen engena e-ceramic eshisa kakhulu yasetshenziswa njenge-reactor ye-catalytic partial oxidation yegesi yemvelo, futhi ukukhiqizwa kwe-oxygen eshibhile kwahlanganiswa ne-catalytic partial oxidation yegesi yemvelo ibe yi-hydrogen ngesikhathi esifanayo. Imiphumela yokuqala yokuhlola ubuchwepheshe kanye nezomnotho ikhombisa ukuthi uma kuqhathaniswa nenqubo yokukhiqiza evamile, ukutshalwa kwezimali kweyunithi kuzoncishiswa cishe ngo-25-30% kanti izindleko zokukhiqiza zizoncishiswa ngo-30-50%.
Ukuqhekeka kwegesi yemvelo ngokushisa okuphezulu ukuze kukhiqizwe i-hydrogen. Ukukhiqizwa kwe-hydrogen kusuka ku-pyrolysis yegesi yemvelo kuwukuqhekeka kwegesi yemvelo ibe yi-hydrogen kanye ne-carbon ekushiseni okuphezulu. Le nqubo ibhekwa njengenqubo yesikhashana phakathi kwamafutha asetshenziswa kudala kanye namandla avuselelekayo ngoba ayikhiqizi i-carbon dioxide. I-Liaohe Oilfield yenze ucwaningo oluningi mayelana nokukhishwa kwe-hydrogen kusuka ekuqhekekeni kwegesi yemvelo ngokushisa okuphezulu. I-carbon ekhiqizwayo ingaba nokusetshenziswa okubalulekile kanye namathuba emakethe abanzi.
Ukukhiqizwa kwe-hydrogen ngokuguqula igesi yemvelo ngokuzenzakalelayo. Uma kuqhathaniswa nenqubo yokuguqula, inqubo ishintsha ukushisa kwangaphandle kube ukuzifudumeza, futhi ukusetshenziswa kokushisa kokusabela kunengqondo kakhulu. Isimiso siwukuthi ukusabela kokushiswa kwegesi yemvelo exothermic kanye nokusabela okunamandla kokuguqula umusi wegesi yemvelo e-endothermic kuhlanganiswe ku-reactor, futhi uhlelo lokuphendula ngokwalo lungazifudumeza. Ngaphezu kwalokho, njengoba ukusabela okunamandla kwe-exothermic kanye nokusabela okunamandla kwe-endothermic ku-reactor yokuguqula okuzenzakalelayo kwenziwa isinyathelo ngesinyathelo, i-reactor isadinga ipayipi lensimbi engagqwali lokushisa eliphezulu njenge-reactor, okwenza inqubo yokuphendula yokuguqula okuzenzakalelayo kwegesi yemvelo ibe nezinkinga zokutshalwa kwezimali okuphezulu kanye nomthamo wokukhiqiza ophansi.
