I am currently doing my graduation project. Could you please tell me what kind of catalyst is generally used in sulfuric acid production in factories? I found three types: S101-2H type, S107-1H type and S108-H type. Then I also found a rubidium-cesium-vanadium series catalyst on cnki. I don’t know what to choose and what to choose based on it. I hope all seniors can give me some advice! Thanks for this.
Catalyst selection mostly provides detailed technical guidance to the supplier, and the basics in the manual are only for reference. Send a message to Pinzi or Boqing, and the answer will be extremely professional, even more awesome than the professor!
Our factory makes sulfuric acid and we use 101 and 107. The number of fillings should be determined based on your output.
We use vanadium pentoxide, high and low temperature catalysts with models S101 and S108.
Like you, I am also doing design, but the objects I design are LP-110 and LP-120 of Mengmok Company. I can't find the relevant information now. I'm sorry.
I don’t have one here either. You don’t have to be on a tree? ? , I have the impression that there are many models in the manual.
You are seeking skin from a tiger, which is equivalent to looking for the recipe of Coca Cola. No one will give it to you. :o One solution is to set a catalyst yourself, assuming its activity, then the dosage is a function of the activity. The dosage is now available for reference, and the activity can be deduced. It's a graduation project anyway, so it doesn't matter if there are some errors, as long as you know how to calculate it. :lol This post was last posted by boqing_Edited by zh on 2009-4-21 15:24 ]
The current deviation between calculation and reality is relatively large. The results calculated through the dynamic model need to be corrected with actual data. There is a certain distance between theory and reality.
Our factory uses two domestic high and low temperature catalysts of vanadium pentoxide model S101 and S108.
At present, the two domestically produced catalysts used most are S101 and S108, accounting for more than 85% of the total. The imported catalysts are the LP series products of Mengmok Company and the VK series products of Topsoe Company.
Vanadium pentoxide, mainly this 2# zxg.wylton
The most common one is vanadium pentoxide, high and low temperature catalysts with models S101 and S108.
If you are doing a graduation project, it should be very simple. I don’t know what the content of your design is. What is the focus? If the design is sulfuric acid, then the choice of catalyst is simple. Just choose the one that is easy to use, such as Bombay and Tops. The reason is that it has good activity, and the imported one is good at removing vanadium. If you specialize in catalysts, you cannot be so general. You must study the activity of the catalyst and the filler of the catalyst in detail. Brother, you have to measure it yourself...
If your design scale is less than 150,000 tons, choose S101 and S108. If your design scale is more than 300,000 tons, Topsoe and MECS are recommended. In terms of conversion rate, there is no difference between domestic and imported products. ； In terms of investment, investment in large-scale catalysts will be correspondingly saved in other expenses. ； The imported ones will be better in terms of pressure resistance and powdering rate... As for cesium catalysts, there is no need to consider them in your graduation project. There are not many industrial applications yet.
