Dab tsi yog Ozone Depletion Catalysts?
Ozone destructive catalysts yog tsim los ntawm cov khoom xyaw nquag manganese dioxide (MnO2) thiab tooj liab oxide (CuO). Lawv yog xim dub los yog xim av tsaus nyob rau hauv tsos thiab tuaj nyob rau hauv columnar, granular, thiab hmoov cov ntaub ntawv. Ozone destructive catalysts feem ntau yog siv los rhuav tshem ozone hauv cov pa tawm, ua kom cov ozone decomposing rau hauv cov pa oxygen ntawm chav tsev kub yam tsis tas yuav muaj zog ntxiv.
Ozone destructive catalysts tau zoo decompose ozone rau hauv oxygen, tshem tawm ozone tsw thiab ua tau raws li emissions. Lub catalyst siv ib txoj kev tshuaj synthesis los tsim cov khoom xyaw nquag, tswj txhua qhov txheej txheem ntawm cov tshuaj tiv thaiv synthesis. Alumina yog siv los ua ib qho kev sib khi, thiab cov khoom xyaw nquag muaj ntau dua 85%. Cov hmoov tsis muaj binder thiab muaj cov ntsiab lus tseem ceeb ntawm ntau dua 99%. Cov catalyst tsis muaj cov pa roj carbon activated, tuaj yeem tiv taus qhov kub thiab txias thaum kho cov ozone siab, tsis kub hnyiab, tsis yog - volatile, nyab xeeb siv, thiab tsis ua rau cov pa phem thib ob.
Ozone destructive catalysts zoo txhim kho kev siv ozone thiab cov mineralization peev xwm ntawm cov organic teeb meem, txo cov nqi khiav lag luam, ua rau lawv zoo tagnrho catalysts rau tom ntej - tiam ozone destructive catalytic oxidation.
