Eyona nto ibalulekileyo kwi-adiabatic ukuguqulwa kwegesi yendalo ibe yi-hydrogenkukuba uninzi lweempendulo zezinto eziluhlaza ziyimpendulo ye-oxidation engaphelelanga, kwaye inyathelo lokulawula isantya liye laba yimpendulo ye-oxidation engaphelelanga ngokukhawuleza, ephucula kakhulu amandla emveliso yeyunithi yokuvelisa i-hydrogen yegesi yendalo. Inkqubo yokuvelisa i-hydrogen yokuguqulwa kwegesi yendalo ye-adiabatic isebenzisa umoya ongabizi njengomthombo we-oxygen. I-reactor eyilwe ngomatshini ohambisa i-oxygen inokusombulula ingxaki ye-hot spot ye-catalyst bed kunye nokusasazwa kwamandla okufanelekileyo. Uzinzo lwempendulo yezinto ezibangela i-catalytic luphuculwe kakhulu ngenxa yokunciphisa indawo eshushu ebhedini. Ukuveliswa kwe-hydrogen encinci kwindawo ye-hydrogen yegesi yendalo yokuguqulwa kwe-adiabatic kwisikhululo se-hydrogenation kunokubonakalisa ngcono amandla ayo okuvelisa aqinileyo. Inkqubo entsha ineengenelo zenkqubo emfutshane kunye neyunithi yokusebenza elula, kwaye inokunciphisa kakhulu iindleko zotyalo-mali kunye nemveliso ye-hydrogen yeyunithi yokuvelisa i-hydrogen encinci kwindawo ye-hydrogen.
Ukunyibilika okungaphelelanga kwegesi yendalo ukuya kwihydrogen. Xa kuthelekiswa nendlela yendabuko yokuguqula umphunga, ukunyibilika okungaphelelanga kwegesi yendalo ukuya kwi-syngas kusebenzisa amandla amancinci kwaye kusebenzisa i-refractory engabizi kakhulu ukufaka i-reactor. Nangona kunjalo, ukunyibilika okungaphelelanga kwegesi yendalo ukuya kwi-hydrogen kwandisa utyalo-mali olubizayo kunye neendleko zokuvelisa i-oksijini yeyunithi yokwahlula umoya ngenxa yenani elikhulu le-oksijini ecocekileyo. I-membrane ye-oxygen ye-ceramic engena kwi-ceramic enobushushu obuphezulu yasetyenziswa njenge-reactor ye-catalytic engaphelelanga ye-oxidation yegesi yendalo, kwaye imveliso ye-oksijini engabizi kakhulu yadityaniswa ne-catalytic engaphelelanga ye-oxidation yegesi yendalo ukuya kwi-hydrogen ngaxeshanye. Iziphumo zokuqala zovavanyo lobuchwephesha noqoqosho zibonisa ukuba xa kuthelekiswa nenkqubo yemveliso eqhelekileyo, utyalo-mali lweyunithi luya kuncitshiswa malunga ne-25-30% kwaye iindleko zemveliso ziya kuncitshiswa ngama-30-50%.
Ukuqhekeka kwegesi yendalo ngobushushu obuphezulu ukuze kuveliswe ihydrogen. Ukuveliswa kwehydrogen kwi-pyrolysis yegesi yendalo kukubola kwegesi yendalo ibe yihydrogen kunye necarbon kubushushu obuphezulu. Le nkqubo ithathwa njengenkqubo yenguqu phakathi kwamafutha efosili kunye namandla avuselelekayo kuba ayivelisi ikhabhoni diokside. I-Liaohe Oilfield yenze uphando oluninzi malunga nokukhutshwa kwehydrogen ukusuka ekuqhekekeni kwegesi yendalo ngobushushu obuphezulu. Ikhabhoni eveliswayo inokuba nokusetyenziswa okubalulekileyo kunye namathuba emarike ebanzi.
Imveliso ye-hydrogen ngokuguqula igesi yendalo ngobushushu obuzenzekelayo. Xa kuthelekiswa nenkqubo yokuguqula, inkqubo itshintsha ubushushu bangaphandle bube kubushushu obuzimeleyo, kwaye ukusetyenziswa kobushushu bokusabela kuyamkeleka ngakumbi. Umgaqo kukuba impendulo yokutsha kwegesi yendalo exothermic kunye nempendulo enamandla yokuguqula umphunga wegesi yendalo endothermic zidityaniswe kwi-reactor, kwaye inkqubo yokusabela ngokwayo inokufezekisa ukuzifudumeza. Ukongeza, ekubeni impendulo enamandla exothermic kunye nempendulo enamandla endothermic kwi-reactor yokuguqula i-autothermal zenziwa inyathelo ngenyathelo, i-reactor isafuna umbhobho wentsimbi engagqwaliyo obushushu obuphezulu njenge-reactor, nto leyo eyenza inkqubo yokuguqula igesi yendalo ibe neengxaki zotyalo-mali oluphezulu kunye namandla aphantsi emveliso.
