摘要：
The adsorption and gas chromatographic properties of zeolites, both modified with carbon and supported as a surface-porous layer, have been studied. Carbonization of zeolites changes the chemical nature of their surface and their molecular sieve properties. In comparison with other adsorbents (carbons, polymers, etc.), modified and supported zeolites are characterized by better selectivity for separation of light-boiling compounds formed in many catalytic reactions. Zeolite-based adsorbents have been used for gas chromatographic analysis of mixtures the analysis of which was a problem or was impossible with traditional chromatographic columns.
