Cov txheej txheem tsim cov roj hydrogen ib txwm muaj

Cov txheej txheem ntws ntawm kev tsim cov hydrogen los ntawm cov roj ntuj muaj plaub chav: kev kho roj pub, kev hloov pauv pa, kev hloov pauv CO thiab kev ntxuav hydrogen.

(1) Lub tshuab kho roj pub feem ntau yog siv rau kev desulfurization ntawm cov roj ntuj, thiab MnO thiab ZnO desulfurizers yog siv los tshem tawm H2S thiab SO2. Lub peev xwm ua tiav ntawm cov roj pub yog loj, yog li lub tshuab compressor centrifugal loj yog xaiv thaum compressing cov roj pub.

(2) Chav hloov pauv pa. Cov pa dej siv ua oxidant los hloov cov hydrocarbons nyob rau hauv qhov kev ua ntawm nickel catalyst kom tau txais cov roj hloov pauv rau kev tsim hydrogen. Hom thiab cov qauv ntawm reformer muaj lawv tus kheej cov yam ntxwv, thiab cov qauv, hom thermal compensation thiab hom kho ntawm cov roj sau sab saud thiab qis dua kuj txawv. Txawm hais tias cov cua sov sib pauv hauv seem convection tau teeb tsa sib txawv, cov txheej txheem ua haujlwm ntawm kev hloov pauv kub siab thiab cov dej carbon piv qis dua tau txais yuav hauv chav hloov pauv pa, uas yog qhov zoo rau kev txhim kho qhov tob ntawm kev hloov pauv thiab txuag cov khoom siv raw.

(3) Chav hloov CO. Cov pa roj xa los ntawm lub tshuab hloov pauv muaj qee qhov Co. lub luag haujlwm ntawm kev hloov pauv yog ua kom co tshuaj tiv thaiv nrog cov pa kom tsim CO2 thiab H2 nyob rau hauv qhov muaj catalyst. Raws li qhov kub ntawm kev hloov pauv, cov txheej txheem hloov pauv tuaj yeem faib ua qhov kub siab hloov pauv (350 ~ 400 ℃) thiab qhov kub nruab nrab hloov pauv (qis dua 300 ~ 350 ℃). Nyob rau hauv xyoo tas los no, vim yog qhov tseem ceeb ntawm kev txuag cov peev txheej, ob theem hloov pauv ntawm CO hloov pauv kub siab thiab qhov kub qis tau raug siv hauv cov txheej txheem teeb tsa ntawm chav hloov pauv, yog li kom txo qis kev siv cov khoom siv raw.

(4) Chav ntxuav Hydrogen. Hauv cov txheej txheem, txhua lub tuam txhab tsim hydrogen tau siv lub tshuab nqus dej siab (PSA) kev ntxuav thiab sib cais nrog kev siv hluav taws xob tsawg los hloov lub tshuab decarbonization thiab purification thiab cov txheej txheem tshuaj methane nrog kev siv hluav taws xob siab, yog li ua tiav lub hom phiaj ntawm kev txuag hluav taws xob thiab ua kom yooj yim rau cov txheej txheem, thiab hydrogen nrog kev ntshiab txog li 99.9% tuaj yeem tau txais ntawm qhov hluav taws xob ntawm chav tsev.
