Usoro mmepụta hydrogen gas sitere n'okike ọdịnala

Usoro mmepụta hydrogen site na gas eke nwere nkeji anọ: ọgwụgwọ gas nri, mgbanwe steam, mgbanwe CO2 na nhicha hydrogen.

(1) A na-ejikarị ihe eji agwọ gas nri eme ihe maka iwepụ gas eke, a na-ejikwa ihe na-egbochi gas MnO na ZnO wepụ H2S na SO2. Ike nhazi nke gas nri buru ibu, yabụ a na-ahọrọ nnukwu ihe na-eme ka gas nri dị elu.

(2) Ngalaba ntụgharị uzuoku. A na-eji uzuoku mmiri dị ka ihe na-eme ka ihe ghara ịdị ọcha iji gbanwee hydrocarbons n'okpuru ọrụ nke nickel catalyst iji nweta gas ntụgharị maka mmepụta hydrogen. Ụdị na nhazi nke onye na-eme mgbanwe nwere njirimara nke ha, nhazi, ụdị nkwụghachi okpomọkụ na ụdị ndozi nke ndị na-anakọta gas elu na ala dịkwa iche. Ọ bụ ezie na edobere ihe ndị na-agbanwe okpomọkụ na ngalaba convection n'ụzọ dị iche, a na-eji paramita ọrụ usoro nke mgbanwe okpomọkụ dị elu na oke carbon mmiri dị ala na ngalaba ntụgharị uzuoku, nke na-enyere aka imeziwanye omimi ntụgharị na ịchekwa oriri ihe eji emepụta ihe.

(3) Ngalaba ntụgharị CO2. Gas nri ezitere site na onye na-eme mgbanwe nwere oke Co. ọrụ nke mgbanwe bụ ime ka co meghachi omume na steam iji mepụta CO2 na H2 n'ihu ihe na-akpali akpali. Dịka okpomọkụ mgbanwe si dị, enwere ike kewaa usoro mgbanwe ahụ n'ime mgbanwe okpomọkụ dị elu (350 ~ 400 ℃) na mgbanwe okpomọkụ dị n'etiti (ala karịa 300 ~ 350 ℃). N'afọ ndị na-adịbeghị anya, n'ihi ntinye aka na nchekwa akụrụngwa, a nabatala usoro ntụgharị nke ọkwa abụọ nke mgbanwe okpomọkụ dị elu na mgbanwe okpomọkụ dị ala na nhazi usoro nke nkeji ntụgharị, iji belata oriri nke ihe ndị e ji emepụta ihe.

(4) Ngalaba nhicha hydrogen. N'ime usoro a, ụlọ ọrụ mmepụta hydrogen ọ bụla ejirila usoro nhicha na nkewa nrụgide (PSA) mee ihe site na iji obere oriri ike dochie usoro decarbonization na nhicha yana usoro kemịkalụ methane na oke oriri ike, iji mezuo ebumnuche nke ịchekwa ike na ime ka usoro ahụ dị mfe, enwere ike nweta hydrogen nwere ịdị ọcha ruo 99.9% na mpụga nke unit ahụ.
