Solution Approach 1:

Thermal energy is extracted and concentrated specifically at the sorbent location within the vessel rather than heating the entire vessel, improving energy utilization efficiency for desorption

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The system recovers and reuses thermal energy from the desorption process, allowing the sorbent to preheat incoming air or prepare for the next adsorption cycle, reducing overall energy input requirements
