SYNTHESIS OF HIGH-SILICONE ZEOLITES

During the study, the synthesis, texture and physicochemical characteristics of high-silica zeolites from bentonite and kaolin were studied. Adsorption isotherms are characteristic of type IV according to the de Boer classification and characterize the adsorption of monocellular substances. On the isotherm in the range P/P0 = 0-0,05, monomolecular adsorption in mesopores and adsorption in micropores are observed. At P/P0 = 0,05, mono- and polymolecular adsorption is observed in mesocytes. P/P0 = 0,05-0,4 is a polymolecular adsorption field. Based on the obtained results, adsorption of gases CO2, H2S and NO2 by absorption of a mixture of salts CaCl2 • ZnCl2 • MnCl2/ HSZ into a synthesized sorbent was investigated. According to the results of the experiments, the dynamic capacity CaCl2•ZnCl2•MnCl2 / HSZ for hydrogen sulfide was 2.76% by weight. The total dynamic capacity of the adsorbent by H2S was higher than 20-25%.
