I seek to understand the theoretical basis for selecting the optimal temperature for the thermal regeneration process of exhausted adsorbents, such as activated carbon loaded with dye molecules.
Should the regeneration temperature be primarily based on the boiling point or sublimation point of the adsorbate? Are there additional factors or considerations that should be taken into account when determining the appropriate temperature ?
During selection of conditions for thermal regeneration, it should be taken into account that the lowest desorption temperature should be higher than the boiling point of VOC, and the highest one should not damage the adsorbate and the adsorbent structure responsible for the adsorption capacity [8], [11], [14].Nov 5, 20

Regeneration, often referred to as reactivation, is a method of thermally processing the activated carbon to destroy the adsorbed components contained on its surface. In regeneration, the adsorbed components are almost completely removed, yielding a regenerated carbon that can again function as an adsorbent.
