Kev siv ntawm titanium-hlau hydrogen cia alloys
1. Hydrogen cia ntim
Hydrogen cia alloys muaj qhov zoo ntawm qhov hnyav thiab me me raws li cov thawv rau khaws cia thiab thauj hydrogen. Kev siv cov hydrogen cia alloys rau hydrogen cia tsis tas yuav tsum muaj kev kub siab, tsis tshua muaj kub cov cuab yeej thiab rwb thaiv tsev ntsuas rau khaws cia cov kua hydrogen, uas yog lub zog txuag, nyab xeeb thiab txhim khu kev qha.
2. Rau kev sib cais thiab kev rov qab los ntawm hydrogen
Kev tsim khoom lag luam feem ntau ua rau muaj ntau cov roj hydrogen uas muaj cov khib nyiab pov tseg. Yog tias hydrogen cia alloy tuaj yeem sib cais, rov ua dua thiab siv tau, nws tuaj yeem txuag tau ntau lub zog.
3. Rau kev tsim cov high-purity hydrogen
Txhawm rau tsim cov khoom siv high-purity hydrogen, hydrogen-muaj impurities tuaj yeem siv rau hauv kev sib cuag nrog hydrogen cia alloy. Thaum hydrogen absorbed, cov impurities yog adsorbed rau saum npoo ntawm cov hlau; Tom qab cov impurities raug tshem tawm, hydrogen tso tawm thiab siab purity hydrogen tau txais.
4. Hydrogen-powered tsheb
Lub thermal efficiency ntawm hydrogen yog siab dua li cov roj av, thiab tsis muaj kuab paug tom qab combustion, uas ua rau lub zeem muag ntawm hydrogen-powered tsheb txaus nyiam heev. Txawm li cas los xij, qhov hnyav ntawm cov khoom siv hydrogen yog hnyav dua li ntawm cov roj tank, uas feem ntau cuam tshuam rau kev ceev ntawm lub tsheb, thiab nws tseem nyob rau hauv kev tshawb fawb thiab kev sim theem.
Titanium-hlau hydrogen cia alloy txoj kev loj hlob
Raws li tsab ntawv ceeb toom tsis ntev los no los ntawm TASS, cov kws tshawb fawb ntawm Tomsk Polytechnic University hauv Russia tau tsim cov thev naus laus zis tshiab rau hydrogen cia hauv cov hlau hydrides. Cov thev naus laus zis siv titanium-hlau alloy ua cov khoom siv hydrogen, rov qab nqus thiab tso tawm hydrogen ntau txhiab zaus tom qab kev ua haujlwm tau txo qis los ntawm tsuas yog 5-10%, tus nqi ntawm cov khoom zoo sib xws rau ib feem peb.
Compression hydrogen cia tam sim no yog txoj kev siv ntau tshaj plaws ntawm hydrogen cia, thiab kev kub siab tso siab dua rau kev ntsuas kev nyab xeeb thaum khaws cia thiab kev thauj mus los. Hauv qhov sib piv, hlau hydride hydrogen cia tuaj yeem txo qhov siab, txo qhov loj ntawm cov khoom siv, thiab lub teb chaws tau siv hlau hydride ua cov khoom siv hydrogen reusable ruaj khov hydrogen cia cov ntaub ntawv.
Kudyarov, tus kws tshaj lij ntawm lub Department of Experimental Physics ntawm Tomsk Polytechnic University, tau taw qhia tias lanthanide alloys sawv cev los ntawm LaNi5 muaj cov khoom siv hydrogen zoo heev thiab tso tawm, thiab yog cov khoom siv dav siv hlau hydride hydrogen, tab sis lawv cov nqi siab yog cov khoom siv hluav taws xob zoo heev. qhov tsis zoo loj, thiab cov khoom siv raw yog nyob ntawm kev xa khoom. Hauv cov ntsiab lus no, lawv tau sim siv titanium-hlau alloys es tsis txhob lanthanide-nickel alloys, uas tuaj yeem txo tus nqi ntau.
Tam sim no, cov kws tshawb fawb hauv tsev kawm ntawv tab tom ua haujlwm ntxiv rau kev txhim kho cov khoom ntawm titanium-hlau alloys rau hydrogen cia, npaj los hloov cov hmoov me me tam sim no nrog cov qauv compact dua thiab ntxiv cov khoom ntxiv uas ua rau cov hlau nplaum thermal conductivity. Cov kev tshawb fawb tau suav nrog hauv "Priority 2030" kev pab nyiaj txiag ntawm Lavxias Ministry of Education thiab Science.
