ABSTRACT:
This invention relates to the use of pore mouth control of zeolite NaA for developing a novel molecular sieve adsorbents and their potential in the separation and purification of gaseous mixtures by the size/shape selective adsorption. More specifically,the invention relates to the manufacture and use of a molecular sieve adsorbent, which is selective towards oxygen from its gaseous mixture with nitrogen and argon by pore mouth control of zeolite NaA with liquid phase alkoxide deposition on the external surface at ambient conditions of temperature and pressure. Thus prepared adsorbent is useful for the separation and purification of nitrogen and argon from its mixture with oxygen.
