In temperature-swing regeneration, there are two steps necessary to acconqilish desorption (1) heat must be added to the adsorbate and adsorbent to raise them to desorption conditions and to provide the mido-thermic heat of desorption (2) the desorbed species must be transferred away from the adsorbent. When the former is the limiting step, it is termed heating- (or stoichiometric-) limited regeneration. The latter is referred to as stripping- (or equilibrium-) limited regeneration. 

LiH is prepared as slurry with light mineral oil and the dispersion has been found to be stable for a long period of time at normal temperature and pressure [83]. The regeneration process is a carbo-thermic reduction process based on the use of low-cost carbon from coal or biomass.
