Cov txheej txheem thev naus laus zis thiab kev piav qhia ntawm cov roj av hydrogen tsim cov nroj tsuag (1)

1) Daim duab qhia txog cov txheej txheem yooj yim ntawm kev tsim cov roj hydrogen los ntawm cov pa roj ntuj

Lus Cim: Lub thawv uas muaj cov cim dotted yog thaj chaw ciam teb ntawm kev tsim cov hydrogen khoom siv, thiab tus neeg muag khoom yog tus saib xyuas thaj chaw hauv lub thawv teev.

2) Txoj Cai Txheej Txheem

Lub skid-mounted kev tsim cov roj hydrogen los ntawm cov pa roj ntuj cov khoom siv feem ntau suav nrog tsib kauj ruam tseem ceeb: kev nias roj av, kev tshem tawm cov roj av zoo, kev hloov kho cov pa roj av, kev hloov pauv CO, thiab kev sib cais thiab kev ntxuav hydrogen.

1) Cov khoom siv raw desulfurization

Cov roj av nyoos raug cua sov rau 320-380 ℃ hauv seem convection ntawm lub reformer thiab tom qab ntawd dhau los ntawm manganese oxide thiab zinc oxide desulfurizers kom tshem tawm cov organic sulfur thiab H2O.₂S nyob rau hauv cov roj nyoos _{mus rau} hauv qab 0.1 ppm kom tau raws li qhov xav tau ntawm cov sulfur ntawm cov catalyst hloov pauv pa. Cov tshuaj tiv thaiv tseem ceeb yog raws li nram no:

H₂S + ZnO → ZnS + H₂TUS

2) Kev kho dua tshiab ntawm cov pa roj av: Tom qab cov pa roj av raug tshem tawm mus rau qis dua 0.1 PPm, nws raug sib xyaw nrog cov pa txheej txheem ntawm qhov sib piv ntawm 3.2 txog 3.5, thiab nkag mus rau hauv cov roj sib xyaw ua ntej cua sov kom tau preheated ntxiv rau 550 txog 600 ° C ua ntej nkag mus rau hauv lub raj kho dua tshiab. Hauv lub txaj catalyst, methane reacts nrog cov pa dej los tsim H₂ thiab CO, thiab CO txuas ntxiv ua rau muaj kev cuam tshuam nrog cov pa dej los tsim CO_2. Lub cua sov uas xav tau rau kev hloov pauv methane yog muab los ntawm kev sib xyaw ntawm cov roj sib xyaw. Thaum muaj cov catalyst nickel, nws cov tshuaj tiv thaiv tseem ceeb yog raws li nram no:

CH₄ +H₂O (pas dej) = CO + 3H₂ -49200Kcal/Kmol (kev hloov pauv)

CO+H₂O (pas dej) = CO₂ +H₂+9840Kcal/Kmol (kev hloov pauv)

Kev tawg ntawm cov alkanes siab dua (400 ~ 600 ℃)

CnH₂n + 2nH₂O (pas dej) = (2n + 1) H₂ + nCO
