Abstract
A process for air cleaning by the removal of water and one or more undesirable gases such as NO.sub.x, SO.sub.x and CO.sub.2 by a continuous atmospheric pressure and low pressure drop system wherein the adsorbent body is a wheel of thin sheets or layers of fibrous material containing about 10 to 90% by weight of a finely divided crystalline molecular sieve material. The process is especially useful for the removal of NO.sub.2 from confined areas.
