Air cleaning adsorption process

Claim 1

A process for air cleaning by the removal of water and one or more undesired gaseous components selected from the group consisting of NO x , SO x and CO 2 by a continuously adsorbing and regenerating of the adsorbent body, atmospheric pressure and low pressure drop process comprising the steps: continuously passing air to be treated through an adsorbent body consisting essentially of thin sheets or layers of fibrous material containing about 10% to about 90% by weight of a finely divided crystalline molecular sieve material for a time sufficient to permit the molecular sieve material to adsorb the NO x , SO x and CO 2 from said air to an acceptable pollutant level and removing dry and clean product air in a first phase; and regenerating said adsorbent body by continuously passing countercurrent to the treatment air through said adsorbent body in a second phase a portion of the dry and clean product air heated to a temperature of more than about 300° F. removing the pollutants from said adsorptive body and then passing a portion of the dry and clean product air countercurrently through said adsorbent body in a third phase until the desired amount of moisture is removed and the adorbent body cooled for recycle of the adsorbent body to the first phase.
