Cov ntshiab hydrogen tau qhia rau lub ntiaj teb kho tsheb kom tau txais cov roj zoo tshaj. Lub peev xwm loj ntawm hydrogen zog thiab cov khoom siv ntau dua tshiab tau ntsib ntau ntawm cov kev xav tau ntawm cov neeg siv khoom niaj hnub no. Hydrogen, txawm li cas los xij, nws muaj nws cov teeb meem. Cov kws tshawb fawb txog science thiab thev naus laus zis tseem niaj hnub ua kom dhau qhov kev tsis txaus ntseeg no, thiab thaum kawg hydrogen yuav dhau los ua cov roj thiab roj ntev ntev. Hauv lub sijhawm, xav txog qhov zoo thiab qhov tsis zoo ntawm cov tsheb hydrogen ntawm lub sijhawm tam sim no.
Hnub Wednesday
Kev siv cov roj ua hluav taws xob hauv cov cav hluav taws xob sab hauv lub cav tsis ua rau muaj cov pa phem. Lub tsheb tseem tuaj yeem tsim cov pa phem los ntawm lwm qhov chaw (xws li hlawv lube roj), tab sis hydrogen li roj tsis ua rau cov pa phem ib puag ncig. Thaum hydrogen sib xyaw nrog huab cua, oxygen thiab hydrogen hlawv kom tsim tau dej.
Rov ua dua tshiab
Hydrogen yog cov khoom siv roj ua dua tshiab. Thaum muab hlawv, dej yog tsim. Nws tuaj yeem ua kom tawg mus rau hauv nws cov khoom sib cais (hydrogen thiab oxygen), ua kom muaj ntau dua hydrogen atoms. Lub voj voog tsis tuaj yeem tawg, vim tias tsis muaj cov tshuaj lom neeg hloov pauv hauv cov txheej txheem uas yuav tshem tawm qhov tsim tawm ntawm hydrogen. Tsis zoo li petrochemicals, hydrogen tuaj yeem siv kom tau txais txiaj ntsig thiab rov qab ua qhov khoom siv roj tsheb.
Qhov Txaj Muag
Hydrogen tsheb tau dhau los ua tus nqi pheej yig dua, tab sis cov cuab yeej kho vaj tse rau kev pabcuam lawv tau poob qis dua. Cov tshuaj hydrogen tsis nqus rau hauv lub tshuab ua kua roj, tab sis ua kua cryogenic (txias heev) ua kua. Nrhiav qhov chaw sam roj hydrogen chaw nres tsheb yuav tsum muaj kev npaj tswv yim thiab dag ntxias kom npog cov chaw nyob deb. Hauv ntau thaj tsam ntawm Lavxias tsis muaj kev tiv thaiv txaus rau cov tsheb hydrogen, cov chaw nres tsheb tau nyob deb ntawm txhua lwm yam.
Hydrogen tsim tawm tsis yog yam dawb. Lub distillation ntawm hydrogen yuav tsum siv lub zog tseem ceeb. Lub tshuab hluav taws xob muaj hluav taws xob hla dej, tsim tawm cov dawb hydrogen thiab oxygen. Hydrogen nce siab saum toj oxygen thiab sau thiab liquefied. Kev siv hluav taws xob thiab liquefaction ntawm hydrogen yog cov txheej txheem siv zog. Qhov no cuam tshuam txog qhov muaj ntawm hydrogen ntawm cov lag luam pub dawb.
Kev xeb
Hydrogen yog cov khoom tawg yooj yim uas sib xyaw yooj yim nrog rau feem ntau lwm cov ntsiab lus. Cov txheej txheem sib txuas no ua rau muaj ntau yam kev cuam tshuam thaum cuam tshuam nrog hlau thiab lwm yam ntaub ntawv. Cov ntshiab hydrogen tau corrode hlau sai heev, thiab cov kev daws teeb meem engineering rau qhov teeb meem no nce tus nqi ntawm lub tsheb tsheb hydrogen. Tsuas hloov cov roj av nrog hydrogen tsis daws teeb meem. Kev siv cav, roj tso tsheb hlau luam thiab cov tshuab yuav tsum tau tsim thiab tshwj xeeb rau cov roj siv hluav taws xob.
