- 17 - ABSTRACT OF THE DISCLOSURE An improved method for the bulk drying of water-containing organic feedstocks by means of selective adsorption of the water in fixed molecular sieve beds wherein the improvement comprises integrating a series of at least four fixed adsorption beds in a manner such that at least two of the beds are always involved in the adsorption-drying phase of the process cycle, and at least two of the beds are always undergoing some portion of the regeneration phase in such a manner that a closed-loop non-condensible purge gas stream used to heat and to cool the beds undergoing regeneration is passed first through the bed being cooled and thereafter through the bed being heated, with the heat energy removed from the former being imparted to the latter.
