Roundd Tsim Alkaline Electrolyzer

Khoom noj khoom haus:
Hydrogen yog dav siv los ua khoom noj khoom haus hauv ntau qhov kev lag luam thiab kev lag luam thiab ua haujlwm tseem ceeb hauv kev tsim cov tshuaj, hauv refineries, steel manufacturing thiab hluav taws xob tsim. Ua Hydrogen los ntawm alkaline dej electrolysis ua rau cov kev lag luam no kom decarbonise.

Kev lag luam tshuaj:
Hydrogen yog ib qho tseem ceeb feedstock, ua ib lub tsev thaiv rau cov synthesis ntawm ntau yam tshuaj tebchaw thiab siv nyob rau hauv zus tau tej cov ammonia, methanol, hydrogen peroxide thiab ntau yam organic tebchaw.

Refineries:
Hydrogen yog siv nyob rau hauv refineries rau hydroprocessing, qhov twg nws yog ua ke nrog hnyav roj av feem kom tshem tawm impurities thiab txhim kho cov khoom roj zoo.

Steel ntau lawm:
Hydrogen yog ua hauj lwm nyob rau hauv cov hlau thiab steel kev lag luam raws li ib tug feedstock los txo cov hlau ore nyob rau hauv cov hlau hlau nyob rau hauv ib tug txheej txheem hu ua direct txo. Qhov no txo ​​cov pa roj carbon emissions cuam tshuam nrog cov txheej txheem tsim khoom ib txwm muaj.

Kev tsim hluav taws xob:
Hydrogen tuaj yeem siv los ua khoom noj rau lub zog tsim hluav taws xob los ntawm kev siv cov roj hluav taws xob thev naus laus zis, uas hloov hydrogen rau hauv hluav taws xob, siv tau los ua lub zog huv.

Mobility:
Kev siv cov hydrogen hauv cov ntawv thov kev txav mus los yooj yim rau kev hloov mus rau kev thauj mus los qis thiab txo qis cov pa roj carbon monoxide emissions. Nws muaj qhov zoo ntawm kev muab lub zog huv thiab ruaj khov rau ntau lub tsheb thiab txoj kev thauj mus los xws li tsheb npav, tsheb thauj khoom, tsheb tavxij, tsheb ntiag tug, thiab txawm tias tsheb ciav hlau thiab nkoj. Hydrogen roj cell tsheb ua kom muaj ntau yam ntev thiab siv sij hawm refueling sai dua thaum piv rau roj teeb hluav taws xob tsheb, tseem ceeb heev kuj txo qhov hnyav.

Roj:
Los ntawm kev hloov hluav taws xob txuas ntxiv mus rau hauv hydrogen los ntawm alkaline dej electrolysis, hydrogen li roj tuaj yeem khaws cia thiab thauj mus rau qhov deb, buffering thiab ntsuas qhov sib cuam tshuam ntawm cov khoom siv hluav taws xob tauj dua tshiab. Cov roj no tuaj yeem siv rau kev tsim hluav taws xob, kev tsim hluav taws xob lossis txawm hloov cov pa roj hauv tsev siv cua sov.

Ib qho alkaline electrolyzer yog ib qho khoom siv uas siv cov tshuaj electrolyte, feem ntau cov poov tshuaj lossis sodium hydroxide, los faib cov dej molecules rau hauv hydrogen thiab oxygen los ntawm cov txheej txheem hu ua electrolysis. Lub hauv paus ntsiab lus tshuaj tom qab alkaline electrolyzer yog raws li cov hauv paus ntsiab lus ntawm electrochemistry. Hauv electrochemistry, tshuaj lom neeg cov tshuaj tiv thaiv yog tsav los ntawm kev hloov ntawm electrons ntawm ib yam khoom mus rau lwm tus. Thaum cov hluav taws xob tam sim no siv rau cov tshuaj electrolyte, nws ua rau cov tshuaj electrolyte mus rau hauv cov txheej txheem hu ua electrolysis. Thaum lub sij hawm tus txheej txheem no, cov hluav taws xob tam sim no ua rau cov dej molecules muab faib ua lawv cov atoms ntawm hydrogen thiab oxygen.

Nyob rau hauv ib qho alkaline electrolyzer, cov txheej txheem yog ua tau los ntawm lub xub ntiag ntawm cov tshuaj electrolyte, uas muaj hydroxide ions (OH-) uas pab txhawb kev hloov ntawm electrons ntawm cov electrodes thiab cov dej molecules. Cov hydroxide ions raug nyiam mus rau qhov zoo them anode (cov electrode txuas nrog lub davhlau ya nyob twg zoo ntawm lub zog hluav taws xob) thiab cov hydrogen ions (H +) raug nyiam mus rau qhov tsis zoo them cathode (cov electrode txuas nrog lub davhlau ya nyob twg tsis zoo ntawm lub zog hluav taws xob) .

● Ntawm lub anode, cov dej molecules yog oxidized los tsim cov pa roj carbon monoxide thiab muaj txiaj ntsig zoo hydrogen ions: 2H2O → O2 + 4H+ + 4e-
● Ntawm cathode, hydrogen ions raug txo kom tsim cov pa roj hydrogen: 4H+ + 4e- → 2H2
● Zuag qhia tag nrho, cov tshuaj tiv thaiv tuaj yeem qhia tau tias: 2H2O → 2H2 + O2

Cov tshuaj electrolyte plays lub luag haujlwm tseem ceeb hauv cov txheej txheem los ntawm kev muab cov khoom nruab nrab rau kev khiav ntawm electrons ntawm cov electrodes thiab cov dej molecules. Cov hydroxide ions hauv cov tshuaj electrolyte kuj tseem pab tswj cov qib pH ruaj khov, uas yog qhov tseem ceeb rau kev ua haujlwm zoo ntawm electrolyzer.
