Catalyst Catalytic Reaction Yam ntxwv

Muaj plaub yam tseem ceeb ntawm cov tshuaj tiv thaiv catalytic, uas tuaj yeem muab tau los ntawm kev txhais thiab tseem ceeb rau kev nkag siab txog kev ua haujlwm ntawm catalysts.

1. Catalysts tsuas tuaj yeem ceev cov tshuaj tiv thaiv uas tuaj yeem nqa tawm thermodynamically. Thaum nug kom tsim cov catalyst rau cov tshuaj tiv thaiv tshuaj tshiab, thawj kauj ruam yog ua qhov ntsuas kub ntawm cov tshuaj tiv thaiv kom pom tias nws puas muaj cov tshuaj tiv thaiv thermodynamically.

2. Lub catalyst tsuas tuaj yeem ceev cov tshuaj tiv thaiv kom sib npaug, thiab tsis tuaj yeem hloov txoj haujlwm sib npaug (sib npaug tsis tu ncua) ntawm cov tshuaj tiv thaiv.

3. Cov catalyst yog xaiv rau cov tshuaj tiv thaiv. Thaum cov tshuaj tiv thaiv yuav muaj ntau tshaj li ib qho kev taw qhia sib txawv, cov catalyst tsuas yog nrawm rau ib qho ntawm lawv, thiab cov tshuaj tiv thaiv tus nqi thiab kev xaiv tau koom ua ke.

4, lub neej ntawm cov catalyst. Lub catalyst tuaj yeem hloov tus nqi ntawm cov tshuaj tiv thaiv, thiab qhov zoo tshaj plaws catalyst tsis hloov los ntawm cov tshuaj tiv thaiv. Txawm li cas los xij, hauv cov txheej txheem tshuaj tiv thaiv tiag tiag, qee qhov hloov tsis tau lub cev thiab tshuaj hloov pauv yuav tshwm sim thaum lub catalyst yog rhuab thiab chemically ua rau lub sijhawm ntev.

Raws li cov ntsiab lus thiab cov yam ntxwv tsom xam ntawm catalysts, muaj peb yam tseem ceeb catalyst indicators, As kev ua, xaiv, thiab stability.
