Process and apparatus for cleaning an impurity-containing adsorbent by pressure swing regeneration, comprising:… (a) warming the impurity-containing adsorbent by direct heat transfer with warm purge gas (2),… (b) heating the cooled-down purge gas to produce hot purge gas (11, 13),… (c) cleaning the warm inpurity-containing adsorbent by contact with hot purge gas (4),… (d) cooling the clean adsorbent by direct heat transfer with clear purge gas to produce warm purge gas of steps (a), (b). |
