ABSTRACT:
In the process for selectively adsorbing NO.sub.x from nitric acid plant acid absorber tower tail gas streams wherein the tailgas stream, comprising water vapor, oxygen, nitrogen and unreacted NO.sub.x is first dried by passage through a silica adsorbent mass and thereafter the NO.sub.x is selectively adsorbed in a zeolitic molecular sieve bed, the improvement which comprises utilizing as the molecular sieve adsorbent a zeolite Y composition having a high degree of ionic character coupled with a high degree of acid stability.
