Adsorption hysteresis in the low-pressure range is only rarely described in the literature. To optimise, for example, heat storage technologies, a deeper understanding of the low-pressure hysteresis (LPH) process is necessary. Here, two thermodynamically based approaches are further developed for analysing the LPH within the framework of thermodynamically irreversible processes and fractal geometry.

- The study reveals that molecular desorption from disordered adsorbents behaves differently than predicted by traditional models at longer times.
- It suggests that while hydrogen desorption from crystalline adsorbents may show second-order effects, this is only relevant at much longer times than when non-Debye behavior is observed.
- A new approach is introduced, emphasizing the role of fluctuations in activation energy, which provides a better understanding of desorption kinetics in both crystalline and amorphous materials.
