A method is disclosed for the thermal regeneration of an adsorbent which contains adsorbed components which can react with and damage the adsorbent at regeneration temperatures. The method comprises passing a hot regeneration gas through a bed of the adsorbent at a sufficiently high flow rate such that the residence time and reaction of the desorbed components in the adsorbent bed are minimized. For removing water from CaX or SrX zeolites, the flow of nitrogen regeneration gas is controlled so that the nitrogen gas residence time in the bed is less than one second.

A method for the thermal regeneration of an adsorbent containing one or more adsorbed reactive components which can react with and damage said adsorbent during regeneration comprising passing at a regeneration temperature a regeneration gas which is essentially free of said reactive components through a bed of said adsorbent which initially contains said adsorbed reactive components at a temperature less than said regeneration temperature whereby said adsorbed reactive components are desorbed, and withdrawing therefrom a purge effluent stream comprising desorbed reactive components and said inert regeneration gas, wherein the flow rate of said regeneration gas is controlled such that the gas residence time in said bed of adsorbent is less than about one second, whereby damage to said adsorbent by reaction with said reactive components at said regeneration temperature is minimized.
