In an adsorption process for the separation of gases, e.g., in the separation of CO2 and H2O from air, wherein gas to be separated is passed through one of several interchangeably connected adsorbers, and a main stream of regenerating gas is passed in two periods through another of said interchangeably connected adsorbers, the first period being a heating period to desorb the adsorbent, and the second period being a cooling period to cool the adsorbent to adsorption temperatures, DURING THE COOLING PERIOD, BRANCHING A PARTIAL STREAM OF REGENERATING GAS FROM THE MAIN STREAM, HEATING THE PARTIAL STREAM WITH THE MEANS, AND PASSING RESULTANT HEATED PARTIAL STREAM OVER A HEAT ACCUMULATOR, AND DURING THE HEATING PERIOD, PASSING THE MAIN STREAM OF REGENERATING GAS ACROSS SAID HEAT ACCUMULATOR TO RECOVER THE HEAT STORED IN THE ACCUMULATOR DURING THE COOLING PERIOD, AND THEN FURTHER HEATING THE MAIN STREAM WITH THE HEATING MEANS TO HEATING PERIOD REGENERATION TEMPERATURES.
