Modification of Zeolites Y and ZSM-5 adsorption of nanoparticles of transition metals from back-micellar solutions for separation of gas mixtures

On the basis of granular synthetic zeolites NaY, HY, and ZSM-5, adsorbents containing nanoparticles silver, cobalt, molybdenum, tungsten were obtained. The samples have a lower surface polarity in comparison with initial zeolites, which is reflected selectivity number respect to argon. This due fact that argon molecule interacts only through nonspecific forces. Modification was performed by interacting reverse-micellar solutions nanoparticles. actual sizes metal particles their distribution over modified been determined method transmission electron microscopy. samples’ equilibrium adsorption capacities for oxygen (25°С atmospheric pressure) separation coefficient argon–oxygen mixture as ratio Henry’s coefficients determined. It has demonstrated NaY zeolite silver value gas equal 1.6.
