Ndozigharị gas sitere n'okike bụ usoro mmepụta dị elu ma tozuo oke nke na-ewulite akụrụngwa na-ebufe pipeline gas dị ugbu a. Nke a bụ ụzọ teknụzụ dị mkpa maka oge dị nsommepụta hydrogen.
Kedu ka Ọ si arụ ọrụ?
Ndozigharị ikuku gas, nke a makwaara dị ka steam methane reforming (SMR), bụ usoro a na-ejikarị eme ihe maka mmepụta hydrogen. Ọ na-agụnye mmeghachi omume nke gas sitere n'okike (nke bụ methane) na uzuoku n'okpuru nrụgide dị elu yana n'ihu ihe na-eme ka ọ bụrụ ihe na-eme ka ọ bụrụ nickel, iji mepụta ngwakọta nke hydrogen, carbon monoxide, na carbon dioxide. Usoro a nwere isi nzọụkwụ abụọ:
Ndozigharị Steam-Methane(SMR): Mmeghachi omume mbụ ebe methane ji uzuoku meghachi omume iji mepụta hydrogen na carbon monoxide. Nke a bụ usoro endothermic, nke pụtara na ọ chọrọ ntinye ọkụ.
CH4 + H2O (+ okpomọkụ) → CO + 3H2
Mmiri-Gas Shift Reaction (WGS): carbon monoxide emepụtara na SMR na-emeghachi omume na uzuoku ka ukwuu iji mepụta carbon dioxide na hydrogen ọzọ. Nke a bụ mmeghachi omume exothermic, na-ahapụ okpomọkụ.
CO + H2O → CO2 + H2 (+ obere okpomọkụ)
Mgbe mmeghachi omume ndị a gasịrị, ngwakọta gas na-esi na ya pụta, nke a maara dị ka synthesis gas ma ọ bụ syngas, na-edozi iji wepụ carbon dioxide na adịghị ọcha ndị ọzọ. A na-esikarị na-eme ka hydrogen dị ọchaadsorption mmetụta nrụgide(PSA), nke na-ekewa hydrogen na gas ndị ọzọ dabere na ọdịiche dị na omume mgbasa ozi n'okpuru mgbanwe nrụgide.
Gịnị kpatara CalaUsoro a?
Ọnụ ahịa bara uru: Gas sitere n'okike bara ụba ma dịkwa ọnụ ala, na-eme SMR otu n'ime ụzọ kachasị ọnụ ahịa maka imepụta hydrogen.
Akụrụngwa: Netwọk pipeline gas dị ugbu a na-enye nri nri dị njikere, na-ebelata mkpa maka akụrụngwa ọhụrụ.
ntozu:Teknụzụ SMRbụ nke ọma nke ọma ma jiri ya mee ihe ruo ọtụtụ iri afọ na mmepụta nke hydrogen na syngas maka ngwa ọrụ mmepụta ihe dị iche iche.
Scalability: Enwere ike ịgbatị osisi SMR iji mepụta hydrogen n'ogo dị mma maka ngwa obere na nnukwu ọnụ.
