ʻO ka hoʻoponopono kinoea kūlohelohe kahi kaʻina hana holomua a oʻo e kūkulu ʻia ma luna o ka ʻōnaehana hoʻouna ʻana i ka pipeline kūlohelohe. He ala ʻenehana koʻikoʻi kēia no ka wā kokokehana hydrogen.
Pehea e hana ai?
Hoʻoponopono kinoea kūlohelohe, ʻike ʻia hoʻi ʻo ka hoʻoponopono hou ʻana o ka methane (SMR), he ala hoʻohana nui ʻia no ka hana hydrogen. Hoʻopili ia i ka pane ʻana o ke kinoea maoli (methane mua) me ka mahu ma lalo o ke kaomi kiʻekiʻe a ma ke alo o kahi catalyst, maʻamau ma ka nickel-based, e hana i kahi hui o ka hydrogen, carbon monoxide, a me carbon dioxide. ʻO ke kaʻina hana he ʻelua mau ʻanuʻu nui:
Hoʻoponopono Mokumahu-Methane(SMR): ʻO ka hopena mua kahi e hana ai ka methane me ka mahu e hana i ka hydrogen a me ka carbon monoxide. He kaʻina hana endothermic kēia, ʻo ia hoʻi, pono ia i ka hoʻokomo wela.
CH4 + H2O (+ wela) → CO + 3H2
Wai-Gas Shift Reaction (WGS): ʻO ke kalapona monoxide i hana ʻia i loko o ka SMR e pane me ka mahu hou aku e hana i carbon dioxide a me ka hydrogen hou. He hopena exothermic kēia, hoʻokuʻu i ka wela.
CO + H2O → CO2 + H2 (+ wahi wela liʻiliʻi)
Ma hope o kēia mau hopena, ua hana ʻia ka hui kinoea i loaʻa, i kapa ʻia ʻo synthesis gas a i ʻole syngas, e wehe i ka carbon dioxide a me nā mea haumia ʻē aʻe. ʻO ka hoʻomaʻemaʻe ʻana o ka hydrogen e loaʻa maʻamau ma okaomi ʻana i ke kaomi ʻana(PSA), ka mea e hoʻokaʻawale i ka hydrogen mai nā kinoea ʻē aʻe e pili ana i nā ʻokoʻa o ka hana adsorption ma lalo o nā loli kaomi.
No ke aha ʻo ChooseʻO kēia kaʻina hana?
Uku-Kumu: He nui ke kinoea maoli a maʻalahi ke kumu kūʻai, e hoʻolilo iā SMR kekahi o nā kumu kumu kūʻai maikaʻi loa no ka hana ʻana i ka hydrogen.
Infrastructure: Hāʻawi ka ʻenehana paipu kinoea kūlohelohe i kahi lako lako meaʻai, e hōʻemi ana i ka pono o nā ʻoihana hou.
Oo:ʻenehana SMRua hoʻokumu maikaʻi ʻia a ua hoʻohana ʻia no nā makahiki he mau makahiki i ka hana ʻana i ka hydrogen a me nā syngas no nā ʻano hana ʻenehana.
Scalability: Hiki ke hoʻonui ʻia nā mea kanu SMR e hana i ka hydrogen i nā nui kūpono no nā noi liʻiliʻi a me ka nui.
