Adsorption of Ar and N2 on dealuminated mordenite tuffs

This paper describes the adsorption of nitrogen and argon on pores in natural mordenites before and after acid leaching treatment. The exchange with H+ ions during dealumination favors the creation of emergent pores thus causing an increase of the adsorption capacity. The development of nanopores in mordenites was evaluated through the Dubinin-Astakhov and Barrett-Joyner-Halenda methods. (C) 2015 The Authors. Published by Elsevier B.V.
