Atụmatụ teknụzụ usoro na nkọwa nke ụlọ ọrụ mmepụta hydrogen gas eke (1)

1) Eserese usoro nhazi nke mmepụta hydrogen nke gas sitere n'okike

Rịba ama: Igbe ntụpọ ahụ bụ mpaghara ókè nke mmepụta hydrogen ngwaọrụ ahụ, onye na-ere ya ga-ahụ maka mpaghara dị n'ime igbe ahụ.

2) Ụkpụrụ Usoro

Ihe e ji skid kpuchie mmepụta hydrogen nke gas sitere n'okike Ngwa ndị a gụnyere usoro ise bụ isi: nrụgide gas sitere n'okike, mwepụ gas sitere n'okike, mgbanwe uzuoku gas sitere n'okike, mgbanwe CO2, na nkewa na nhicha hydrogen.

1) Mwepụ ihe onwunwe

A na-ekpo ọkụ gas sitere n'okike ruo 320-380℃ na ngalaba convection nke onye na-eme mgbanwe ahụ wee gafee manganese oxide na zinc oxide desulfurizers iji wepụ sọlfọ organic na H.₂S na gas a na-anaghị amị amị _na Ọ dị n'okpuru 0.1ppm iji mezuo ihe achọrọ maka sọlfọ nke ihe na-eme ka steam reforming catalyst. Mmeghachi omume ndị bụ isi bụ ndị a:

H₂S +ZnO→ ZnS + H₂IHE

2) Mgbanwe uzuoku gas sitere n'okike: Mgbe ewepụsịrị sọlfọ gas sitere n'okike ruo n'okpuru 0.1 PPm, a na-agwakọta ya na uzuoku usoro na oke nke 3.2 ruo 3.5, wee banye na igwe ọkụ gas agwakọtara ka e wee kpoo ya ọkụ ruo 550 ruo 600 °C tupu ọ banye na tube nhazi. N'ime akwa ihe na-eme ka ihe dị nro, methane na-emeghachi omume na uzuoku mmiri iji mepụta H₂ na CO, na CO na-aga n'ihu na-emeghachi omume na uzu mmiri iji mepụta CO_2. Okpomọkụ dị mkpa maka mgbanwe methane na-esite na ọkụ nke gas agwakọtara mmanụ. N'ihu ihe na-akpali nickel, mmeghachi omume ya bụ isi bụ ndị a:

CH₄ +H₂O (ụzuoku) = CO +3H₂ -49200Kcal/Kmol (mmeghachi omume ntụgharị)

CO+H₂O (ụzuoku) = CO₂ +H₂+9840Kcal/Kmol (mmeghachi omume ntụgharị)

Mmeghachi omume mgbawa nke alkanes dị elu (400 ~ 600℃)

CnH₂n + 2nH₂O (ụzuoku) =(2n+1) H₂ + nCO
