Hengzhong chav tsim hydrogen rau cov roj av

Kev Taw Qhia

Cov txheej txheem tsim cov hydrogen ntawm cov roj ntuj feem ntau suav nrog plaub txoj hauv kev: kev kho ua ntej roj pub, kev hloov pauv pa roj ntuj, kev hloov pauv carbon monoxide thiab kev ntxuav hydrogen.

Kauj ruam thawj zaug yog kev kho ua ntej ntawm cov khoom siv raw. Kev kho ua ntej ntawm no feem ntau yog hais txog kev desulfurization ntawm cov roj nyoos. Hauv kev ua haujlwm tiag tiag, cov roj av cobalt molybdenum hydrogenation series zinc oxide feem ntau yog siv los ua cov desulfurizer los hloov cov organic sulfur hauv cov roj av mus rau hauv cov inorganic sulfur thiab tom qab ntawd tshem tawm nws. Cov dej ntws ntawm cov roj av nyoos kho ntawm no yog loj, yog li qhov chaw roj av nrog lub siab siab tuaj yeem siv lossis qhov loj ntawm ntug tuaj yeem xav txog thaum xaiv cov compressor roj av.

Kauj ruam thib ob yog kev hloov pauv pa ntawm cov roj av. Cov tshuaj catalyst nickel siv rau hauv lub tshuab hloov pauv los hloov cov alkanes hauv cov roj av mus rau hauv cov roj pub nrog cov khoom tseem ceeb ntawm carbon monoxide thiab hydrogen.

Tom qab ntawd, cov pa roj carbon monoxide raug hloov pauv kom sib xyaw nrog cov pa dej hauv qhov muaj cov tshuaj catalyst los tsim cov hydrogen thiab carbon dioxide kom tau txais cov roj hloov pauv uas cov khoom tseem ceeb yog hydrogen thiab carbon dioxide. Raws li qhov kub hloov pauv sib txawv, cov txheej txheem hloov pauv ntawm cov pa roj carbon monoxide tuaj yeem muab faib ua ob hom: hloov pauv kub nruab nrab thiab hloov pauv kub siab. Qhov kub hloov pauv kub siab yog li 360 ℃, thiab cov txheej txheem hloov pauv kub nruab nrab yog li 320 ℃. Nrog rau kev txhim kho ntawm kev tiv thaiv kev siv tshuab, kev teeb tsa ob theem ntawm cov txheej txheem ntawm cov pa roj carbon monoxide kub siab thiab hloov pauv kub qis tau raug siv nyob rau xyoo tas los no, uas tuaj yeem txuag tau kev siv cov peev txheej ntxiv. Txawm li cas los xij, rau qhov xwm txheej uas cov ntsiab lus carbon monoxide hauv cov roj hloov pauv tsis siab, tsuas yog hloov pauv kub nruab nrab tuaj yeem siv tau.

Kauj ruam kawg yog ntxuav hydrogen. Tam sim no feem ntau siv hydrogen purification system yog PAS system, tseem hu ua PSA purification thiab separation system. Lub system no siv hluav taws xob tsawg, yooj yim thiab purity siab ntawm hydrogen ntau lawm. Thaum siab tshaj plaws, qhov purity ntawm hydrogen tuaj yeem ncav cuag 99.99%.
