Tlhahiso ea Haedrojene: Phetoho ea Khase ea Tlhaho

Phetoho ea khase ea tlhaho ke ts'ebetso e tsoetseng pele le e seng e holile ea tlhahiso e hahelletsoeng holim'a meaho e teng ea phepelo ea lipeipi tsa tlhaho. Ena ke tsela ea bohlokoa ea theknoloji bakeng sa nako e haufitlhahiso ea haedrojene.

E Sebetsa Joang?

Phetoho ea khase ea tlhaho, eo hape e tsejoang e le steam methane reforming (SMR), ke mokhoa o sebelisoang haholo bakeng sa tlhahiso ea haedrojene. E kenyelletsa karabelo ea khase ea tlhaho (haholo-holo methane) ka mouoane o tlas'a khatello e matla le ka pel'a mokelikeli, oo hangata o thehiloeng ho nickel, ho hlahisa motsoako oa hydrogen, carbon monoxide le carbon dioxide. Ts'ebetso e na le mehato e 'meli ea mantlha:

Phetoho ea Mouoane-Methane(SMR): Boitšoaro ba pele moo methane e kopanang le mouoane ho hlahisa hydrogen le carbon monoxide. Ena ke ts'ebetso ea endothermic, ho bolelang hore e hloka ho kenya letsoho mocheso.

CH4 + H2O (+ mocheso) → CO + 3H2

Water-Gas Shift Reaction (WGS): Carbon monoxide e hlahisoang ho SMR e sebetsa ka mouoane o mongata ho etsa carbon dioxide le hydrogen e eketsehileng. Ena ke karabelo e makatsang, e lokollang mocheso.

CO + H2O → CO2 + H2 (+ mocheso o monyenyane)

Ka mor'a liketso tsena, motsoako oa khase o hlahang, o tsejoang e le synthesis gas kapa syngas, o sebelisoa ho tlosa carbon dioxide le litšila tse ling. Ho hloekisoa ha hydrogen hangata ho finyelloa kakhatello ea khatello ea maikutlo(PSA), e arolang haedrojene ho likhase tse ling ho latela phapang ea boitšoaro ba adsorption tlas'a liphetoho tsa khatello.

Ke hobane'ng ha ChoseMokhoa ona?

Tšebeliso ea Litšenyehelo: Khase ea tlhaho e ngata ebile e batla e le theko e tlaase, e leng se etsang hore SMR e be e 'ngoe ea mekhoa e bolokang chelete e ngata ea ho hlahisa haedrojene.

Meralo ea motheo: Marang-rang a teng a lipeipi tsa khase ea tlhaho a fana ka phepelo e seng e ntse e le teng ea lijo, ho fokotsa tlhokeho ea meralo e mecha.

Khōlo:Theknoloji ea SMRe thehiloe hantle 'me e sebelisitsoe lilemo tse mashome ho hlahisa haedrojene le li-syngas bakeng sa lits'ebetso tse fapaneng tsa indasteri.

Scalability: Limela tsa SMR li ka lekanngoa ho hlahisa haedrojene ka bongata bo loketseng lits'ebetso tse nyane le tse kholo.
