Cov pa roj carbon monoxide tshem tawm Catalysts
Cov pa roj carbon monoxide muaj nyob hauv ntau lub mines. Cov pa roj no muaj kev phom sij rau tib neeg thiab tuaj yeem ua rau tuag taus. Txhawm rau tiv thaiv cov neeg ua haujlwm kev nyab xeeb, cov kws tshawb fawb tau tsim cov pa roj carbon monoxide tshem tawm thiab siv lawv rau lub ntsej muag lub ntsej muag. Cov catalysts no tsis tsuas yog tiv thaiv cov neeg ua haujlwm nkaus xwb tab sis kuj tseem nyob ntawm - cov neeg ua haujlwm hauv chaw thiab cov neeg ua haujlwm cawm hauv hluav taws.
VOCs Tshem Tawm Catalysts
Nrog rau kev nruj me ntsis hauv lub tebchaws ib puag ncig kev tiv thaiv, cov qauv emission rau VOCs (volatile organic compounds) tau dhau los ua nruj dua. Yav dhau los, tus qauv emission rau tsis yog -methane tag nrho cov hydrocarbons yog<120 mg/Nm³, but now some regions have reduced it to <40 mg/Nm³. In the chemical industry, exhaust gas treatment has always been a major challenge. Now, catalytic combustion of exhaust gas to recover heat and generate electricity solves both the emission problem and improves economic efficiency.
Roj teeb Dehydrogenation Catalysts
Ntau tus neeg yuav tsis paub tias nickel-hlau hydride thiab lithium roj teeb ua rau muaj pes tsawg leeg ntawm hydrogen thiab organic teeb meem thaum them thiab tawm. Thaum cov hydrogen concentration ntau tshaj 4%, muaj kev pheej hmoo ntawm tawg. Yog li ntawd, qee cov tuam ntxhab tau tsim cov dehydrogenation catalysts rau kev siv nyob rau hauv chav tsev kub, zoo txhim khu kev ruaj ntseg roj teeb.
Peb -txoj kev catalytic converter
Peb -txoj kev catalytic converter yog ib qho ntawm feem ntau catalysts siv nyob rau hauv tsheb. Nws lub luag haujlwm tseem ceeb yog hloov cov nitrogen oxides thiab cov organic teeb meem tawm ntawm lub tsheb mus rau hauv tsis muaj nitrogen, carbon dioxide, thiab dej, yog li purifying ib puag ncig. Peb -txoj kev catalytic converter ua lub luag haujlwm tseem ceeb hauv kev kho tsheb tsheb.
