From the adsorption studies at different temperatures, i have calculated the heat of adsorption for the adsorbent. Using this value, how can we calculate the regeneration temperature? or can we calculate this temperature using any other method?
There is no specific regeneration temperature. You can regenerate your adsorbent at any temperature. It is just a matter of time it will take.
Christoph Hahn Thanks for your answer. However, I would like to ask, the minimum temperature required to regenerate the adsorbent. Since different materials have different affinities towards gas molecules (in my case it is CO2), some requires less heat input, some might require more heat input. I would like to know the minimum threshold which we have to cross to get the regenerated adsorbent. For instance zeolites has temp range of 150-300 degree Celsius of regeneration temperature, whereas MOFs need less temp typically less than 100. I would be happy for your reply. Thanks in advance.
Your measured heat of adsorption is the result of the difference between the activation energies of the adsorption and desorption processes (consider them as chemical reactions reaching an equilibrium point depending on temperature and pressure). So if you want to have a certain temperature you have to define certain process parameters where you want to perform your regeneration and in which time this process should be finished. As you see this is a pure kinetic issue, where you may have to determine the adsorption and desorption kinetic.
