Regarding the issue of carbon dioxide residence time
Thread Content
When using a fixed-bed to absorb carbon dioxide, with a bed length of 1.2 m, what is an appropriate residence time? Thank you!
You should also take into account the properties of your adsorbent, such as its adsorption capacity, particle size, specific surface area, and other factors. If it is a regular commercially available adsorbent, then find a reference paper to see what the empty tower gas velocity is there, and use that as a guide
It is related to your adsorption time, as well as the space velocity, etc.
