Imveliso yeHydrojeni: Ukuguqulwa kweGesi yeNdalo

Uhlaziyo lwerhasi yendalo yinkqubo yemveliso ekwinqanaba eliphezulu nesele ikhulile eyakhela phezu kwesiseko sokuhanjiswa kwerhasi yendalo ekhoyo. Le yindlela ebalulekileyo yetekhnoloji yexesha elisondeleyoimveliso ye-hydrogen.

Ingaba isebenza kanjani?

Ukuguqulwa kwegesi yendalo, ekwaziwa ngokuba yi-steam methane reforming (SMR), yindlela esetyenziswa ngokubanzi kwimveliso yehydrogen. Ibandakanya ukusabela kwegesi yendalo (ikakhulu i-methane) kunye nomphunga phantsi koxinzelelo oluphezulu kunye nobukho be-catalyst, ngokuqhelekileyo i-nickel-based based, ukuvelisa umxube we-hydrogen, i-carbon monoxide, kunye ne-carbon dioxide. Inkqubo inamanyathelo amabini angundoqo:

Ukuguqulwa kweSteam-Methane(SMR): Ukusabela kokuqala apho imethane idibana nomphunga ukuvelisa ihydrogen kunye necarbon monoxide. Le yinkqubo ye-endothermic, oku kuthetha ukuba ifuna igalelo lobushushu.

CH4 + H2O (+ ubushushu) → CO + 3H2

I-Water-Gas Shift Reaction (WGS): I-carbon monoxide eveliswe kwi-SMR isabela ngomphunga omninzi ukwenza i-carbon dioxide kunye ne-hydrogen eyongezelelweyo. Oku kusabela kwe-exothermic, ukukhulula ubushushu.

CO + H2O → CO2 + H2 (+ ubushushu obuncinane)

Emva koku kusabela, umxube werhasi ophumayo, owaziwa ngokuba yigesi ye-synthesis okanye i-syngas, ucutshungulwa ukususa ikharbon diokside kunye nobunye ukungcola. Ukucocwa kwe-hydrogen ngokuqhelekileyo kufezekiswa ngokusebenzisauxinzelelo swing adsorption(PSA), eyahlula i-hydrogen kwezinye iigesi ngokusekelwe kwiiyantlukwano ekuziphatheni kwe-adsorption phantsi kweenguqu zoxinzelelo.

Kutheni uCihubhuLe nkqubo?

Iindleko-zokusebenza: Irhasi yendalo ininzi kwaye ayibizi kakhulu, nto leyo eyenza i-SMR ibe yeyona ndlela ineendleko zokuvelisa i-hydrogen.

Iziseko zophuhliso: Uthungelwano lwemibhobho yerhasi yendalo ekhoyo ibonelela ngobonelelo olusele lukhona lwesondlo, lunciphisa imfuno yeziseko ezingundoqo ezitsha.

Ukukhula:Itekhnoloji ye-SMRisekwe kakuhle kwaye isetyenziswe amashumi eminyaka kwimveliso ye-hydrogen kunye ne-syngas kwizicelo ezahlukeneyo zemizi-mveliso.

I-Scalability: Izityalo ze-SMR zinokulinganiswa ukuze zivelise i-hydrogen ngokobungakanani obufanelekileyo kuzo zombini usetyenziso oluncinci kunye nolukhulu.
