Description

Пример 1. Через слой сульфокатионита КУ - 23 10/60 общей массой 24 г, содержащего 20% диметиламина от веса адсорбента, пропускают поток Смесн, содержащей 5% озона , остальное воздух, со скоростью 0,5 л1мин три температуре 150° С. Через б ч конверси  озона прекращаетс . Катионит промывают 1.0%-ной азотной кислотой в количестве трех объемов с удельной нагрузкой 1 и получают 13,5%-ную азотную кислоту. Окончательную отмывку «атионита провод т водой. Общий привес азотной -кислоты составл ет 72% от теоретически ожидаемого. Степень регенерадии катионита составл ет 99,0%.Example 1. Through a layer of sulfonic cation exchanger KU - 23 10/60 with a total weight of 24 g, containing 20% dimethylamine by weight of the adsorbent, a mixture of 5% ozone and the rest of the air is passed through at a rate of 0.5 l1min three to 150 ° C bh ozone conversion is stopped. The cation exchanger is washed with 1.0% nitric acid in an amount of three volumes with a specific load of 1 and 13.5% nitric acid is obtained. The final washing of the "ationite" is carried out with water. The total weight gain of nitric acid is 72% of the theoretically expected. The degree of regeneration of the cation exchanger is 99.0%.

Пример 2. Регенерацию провод т по примеру 1, но при 80° С. Конверси  озона прекращаетс  через 7 ч. Степень регенерации составл ет 99,0%.Example 2. The regeneration is carried out as in Example 1, but at 80 ° C. The ozone conversion stops after 7 hours. The degree of regeneration is 99.0%.

Пример 3. Регенерацию провод т по примеру 1, но при -20° С. Конверси  озона прекращаетс  через 12 ч. Степень регенерации составл ет 98,9%.Example 3. The regeneration is carried out as in Example 1, but at -20 ° C. The ozone conversion stops after 12 hours. The degree of regeneration is 98.9%.

В таблице 1 приведены сравнительные данные по восстановлению эффективности катионита КУ-i23 10/60 после регенерации и -степени улавливани  азотной кислоты на адсорбенте .Table 1 shows comparative data on the restoration of the effectiveness of the cation exchanger KU-i23 10/60 after regeneration and degree of nitric acid trapping on the adsorbent.
