Abstract

Abstract: By means of elemental and X-ray powder diffraction analysis, N₂ adsorption at –196°C and CO₂ adsorption at 0°C the textural properties of KNaLSX zeolite were studied after ion exchange modification in 1M NH₄Cl solution followed by vacuum degassing at 40°C or drying in air at 120°C. The possibility of retaining the microporous structure of zeolite in the former case and its partial destruction in the latter case is shown.
