Abstract
The regeneration phase of the adsorption cycle includes a depressurization step, a heating/elution step, during which the bed is purged with a hot heating/elution gas, and a cooling/elution step, during which the bed is purged with a cold cooling/elution gas. The cooling/elution step is terminated while the cooling/elution gas leaving the bed is at a temperature markedly higher than the temperature of the gas to be treated and the adsorption phase comprises an initial adsorption step during which the bed is cooled down to the low adsorption temperature due to the effect of the gas to be treated.
