FAQ
Q: Dab tsi yog qhov kev pab cuam lub neej ntawm cov catalyst hauv kev ua haujlwm tas mus li?
A: Kev pabcuam lub neej nyob ntawm qhov ruaj khov ntawm cov pa roj muaj pes tsawg leeg, tshwj xeeb tshaj yog cov pa oxygen hloov pauv, cov dej noo, thiab muaj cov tshuaj lom catalyst xws li sulfur compounds. Thaum ua haujlwm nyob rau hauv qhov pom zoo qhov kub thiab txias qhov chaw nrawm nrawm, muaj kev ruaj khov -txoj kev teeb tsa lub txaj feem ntau ua tiav ntau- xyoo ua haujlwm ua ntej yuav hloov lossis rov tsim dua tshiab.
Q: Cov catalyst no puas tuaj yeem ua haujlwm hauv cov dej noo lossis cov pa roj carbon dioxide?
A: Yog lawm, cov txheej txheem tuaj yeem ua raws li cov qib dej vapor thiab carbon dioxide. Txawm li cas los xij, vim tias cov dej noo siab lossis siab carbon dioxide siab tuaj yeem cuam tshuam rau qis - qhov kub thiab txias kev ua haujlwm thiab cov tshuaj tiv thaiv sib npaug, cov khoom siv no yuav tsum tau nthuav tawm tag nrho thaum lub sij hawm ntsuam xyuas cov txheej txheem yog li cov qib tsim nyog thiab lub txaj qhov tob tuaj yeem xaiv tau.
Q: Yuav ua li cas yog tus txheej txheem yog tias cov pa roj muaj cov kab sib txuas sulfur?
A: Txheeb xyuas cov tshuaj sulfur xws li hydrogen sulfide thiab carbonyl sulfide tuaj yeem ua raws li cov tshuaj lom catalyst nyob ntawm lub sijhawm ua haujlwm. Yog hais tias leej faj muaj nyob rau hauv qhov pub, ua ntej - cov txaj txaj txaj lossis leej faj- cov tshuaj tiv thaiv catalyst yuav tsum tau siv. Muab tag nrho cov qib sulfur ppm thaum lub sijhawm nug thawj zaug ua kom muaj kev tiv thaiv sab saud thiab xaiv cov khoom siv catalyst.
Q: Yuav ua li cas yog qhov yuav tsum tau catalyst ntim rau ib tug ruaj - txaj reactor?
A: Catalyst ntim yog txiav txim siab los ntawm kev ntsuas tus qauv tsim cov roj ntws, kev ua haujlwm siab, qhov kub thiab txias, thiab lub hom phiaj roj ib teev qhov chaw tshaj tawm. Cov txheej txheem engineers suav lub sijhawm nyob hauv qhov tsim nyog kom ua tiav qhov yuav tsum tau muaj qhov hluav taws xob oxygen tshwj xeeb thaum ua kom lub siab poob qis hauv kev txwv rau lub nkoj reactor.
Q: Puas muaj peev xwm rov tsim dua tshiab, lossis puas siv cov catalyst xav tau hloov?
A: Nyob ntawm cov txheej txheem hlau tshwj xeeb thiab qhov tshwm sim ntawm qhov tsis ua haujlwm (xws li cov pa roj carbon deposition lossis me me sulfur raug), qee cov formulations tso cai rau hauv -situ los yog ex-situ regeneration txheej txheem. Txawm li cas los xij, rau kev siv deoxygenation sib sib zog nqus, siv cov khoom siv feem ntau yog hloov thaum kawg ntawm nws cov kev pabcuam ntau xyoo - xyoo. Cov lus qhia tshwj xeeb tuav thiab pov tseg yog muab thaum thov.
