May I ask about the catalyst volume in the definition of air velocity?
Thread Content
Question: In the formula for volume space velocity = raw material volume flow rate/catalyst volume, does the catalyst volume refer to the actual volume of the catalyst, or to the total reaction volume after it has been loaded? Thank you
Looking for the answer too. Recently, this issue also needs to be considered; it seems that the literature doesn’t explain it clearly. Or rather, I didn’t understand it properly
The connection found online is discussed in great detail; I hope it will be helpful to you. Let’s discuss it together! http://wenku.baidu.com/view/feedbc03eff9aef8941e06da.html
Bulk volume, which can also be used to express the space velocity in terms of catalyst mass
