How is the activity of a catalyst evaluated? Such as catalysts for deoxygenation in hydrogen! Discuss high-score rewards
Thread Content
Apart from removing trace amounts of oxygen from hydrogen, there is a reactor filled with a catalyst; different manufacturers may use different catalysts. First, let me talk about a situation I encountered: I was using a Pd catalyst, and now I have a question – how can one evaluate the activity of a catalyst? ? Besides detecting the oxygen concentration in hydrogen directly, are there any other methods—such as directly examining the structure of the catalyst—to evaluate its activity? ? Please, experienced sailors, feel free to share your thoughts – high scores will be rewarded!! @arpcd @yjqin1 @DesertFish @gavinzhaozt @longkui1990 @Anny’sBaby @ThankfulForYou
Typical of Rili – this type of catalyst is something I’ve heard of for the first time. What you mean is probably catalyst analysis, right? Such as specific surface area, distribution of active sites, etc.
Yes, Brother Scallion – it refers to some structural analyses of the catalyst, things like specific surface area and so on. Usually, when evaluating a catalyst’s activity, we just conduct experiments to check its deoxygenation efficiency. But I want to assess it based on the catalyst’s structure; I wonder if anyone here has experience in this area? It feels like something a graduate student would do~~
You can find a book to get an overview first; currently, in universities there are those who specialize in catalyst characterization, and indeed it is mostly graduate students who do this work. The instruments are all quite sophisticated.
