Description
(54) СПОСОБ ПОЛУЧЕНИЯ ГРАНУЛИЮВАННЫХ СИНТЕТИЧЕСКИХ ЦЕОЛИТОВ Адсорбент можно получить в любой катионообменной форме путем обработки полученных гранул растворами соответствующих солей. Пример 1. 2,5 кг кристаллического цео;ш1а Na А смепшвают с 0,5 кг природного св зующего пластичным каолинитом, имеющим размеры частиц 300 А. Смесь увлажн ют водой дл получени массы удобной дл формовани , и формуют з ввде гранул Полученные гранулы прокаливают при теьшературе 650°С в течение 20 ч. Полученный синтетический цеолит МаАсо св зующим материалом имеет следзшвдие характеристики: Насьшна масса, г/см Прочность на раздавливание, кг на 1 сферическую гранулу ( d 2,7 мм) Динамическа активность по парам воды, мг/см Виброизнос (прочность на истирание), менее 0 более 97 Водостойкость, масс.% Пример 2. 2 кг цеолитного порошка Na с размером кристаллов 1-5 мкм смешивают с 0,6 к природного св зующего материала - гидрослюдой с размером частип 500 А. Полученную смесь обрабатывают аналогично примеру 1, однако при выщелачивании используют раствор NaOH при температуре 75°С, а повторное прокаливание гранул провод т при температуре 350°С в течение 24ч. Полученный синтетический цео. типа На X со св зующим имеет следующие характеристики: Насьшна масса, г/см0,70 Прочность на раздавливание, кг на 1 гранулу (d 2,5 мм)3,2(54) METHOD FOR OBTAINING GRANULE-DUCTED SYNTHETIC ZEOLITES The adsorbent can be obtained in any cation-exchange form by treating the obtained granules with solutions of the corresponding salts. Example 1. 2.5 kg of crystalline zeo; w1a NaA is mixed with 0.5 kg of natural binder with plastic kaolinite having a particle size of 300 A. The mixture is moistened with water to obtain a mass suitable for shaping, and molded into vvde granules The obtained granules are calcined at a temperature of 650 ° C for 20 hours. The obtained synthetic zeolite MaAso binder material has the following characteristics: Weight, g / cm Crush strength, kg per 1 spherical granule (d 2.7 mm) Dynamic activity by water vapor, mg / cm Vibration wear (abrasion resistance less than 0 more than 97 Water resistance, wt.% Example 2. 2 kg of zeolite Na powder with a crystal size of 1-5 μm are mixed with 0.6 to a natural binder material — hydromica with a particle size of 500 A. The resulting mixture is treated similarly to the example 1, however, when leaching, a solution of NaOH is used at a temperature of 75 ° C, and the re-calcination of the granules is carried out at a temperature of 350 ° C for 24 hours. The resulting synthetic ceo. Type X with a binder has the following characteristics: Usage weight, g / cm0.70 Crush strength, kg per 1 granule (d 2.5 mm) 3.2
