Noble gaseskrypto uan thiabxenonyog nyob rau sab xis ntawm lub sij hawm lub rooj thiab muaj cov tswv yim thiab tseem ceeb siv. Piv txwv li, ob qho tib si yog siv rau teeb pom kev zoo.Xenonyog qhov muaj txiaj ntsig ntau dua ntawm ob, muaj kev siv ntau dua hauv tshuaj thiab kev siv tshuab nuclear.
Tsis zoo li natural gas, uas yog plentiful underground,krypton uathiabxenonua kom tsuas yog ib feem me me ntawm lub ntiaj teb huab cua. Txhawm rau sau lawv, cov pa roj yuav tsum mus dhau ntau lub voj voog ntawm cov txheej txheem siv hluav taws xob hu ua cryogenic distillation, uas huab cua raug ntes thiab txias mus txog -300 degrees Fahrenheit. Qhov txias txias no cais cov pa roj raws li lawv qhov kub kub.
Ib tug tshiabkrypton uathiabxenonkev sau tshuab uas txuag hluav taws xob thiab nyiaj txiag yog qhov xav tau heev. Cov kws tshawb fawb tam sim no ntseeg tias lawv tau pom cov txheej txheem zoo li no, thiab lawv txoj kev tau piav qhia hauv Phau Ntawv Xov Xwm ntawm American Chemical Society.
Pab neeg tsim cov khoom siv hluav taws xob silicoaluminophosphate (SAPO), siv lead ua muaj cov pores me me. Qee zaum qhov pore loj yog nruab nrab ntawm qhov loj ntawm krypton atom thiab axenonatom. Me mekrypton uaatoms tuaj yeem yooj yim dhau los ntawm qhov pores thaum loj xenon atoms tau daig. Yog li, SAPO ua zoo li molecular sieve. (Saib daim duab.)
Siv lawv cov cuab yeej tshiab, cov kws sau ntawv tau qhia tiaskrypton uadiffuses 45 npaug sai duaxenon, qhia tau hais tias nws efficiency nyob rau hauv noble gas sib cais ntawm chav tsev kub. Cov kev sim ntxiv tau pom tias tsis yog tsuas yog xenon tawm tsam kom nyem los ntawm cov pores me me no, tab sis nws kuj nyiam adsorb mus rau SAPO crystals.
Hauv kev xam phaj nrog ACSH, cov kws sau ntawv tau hais tias lawv qhov kev txheeb xyuas yav dhau los tau pom tias lawv txoj kev tuaj yeem txo lub zog xav tau los saukrypton uathiab xenon li ntawm 30 feem pua. Yog tias qhov no muaj tseeb, cov kws tshawb fawb txog kev lag luam thiab cov neeg nyiam lub teeb fluorescent yuav muaj ntau yam txaus siab rau.
