Description
Дл достижени данной цели в качест- « ве реакционного агента берут азодикарбамид, а прокаливание ведут при 250-400°С. Азодикарбамид берут в количестве 5-ЗО вес. %, а прокаливание ведут со скоростью подъема температуры , Применение 5-ЗОвес.% азодикарбамида, способного разлагатьс при нагревании с выделением газообразных продуктов, и осуществление прокаливани сформованного поглотител при 250-400°С со скоростью подъема температуры 5-25°С в час, обеспечивающей равномерное выделение газа при разложении азодикарбамида, позвол ет гвеличить поверхность и активность сорбента и тем самым повысить степень очистки газов.To achieve this goal, azodicarbamide is taken as the reaction agent, and calcination is carried out at 250-400 ° C. Azodicarbamide take in the amount of 5-ZO weight. %, and calcination is carried out at a rate of temperature rise, the use of 5-ZOfW.% azodicarbamide, which can decompose when heated to produce gaseous products, and calcining the formed absorber at 250-400 ° C with a temperature rise rate of 5-25 ° C per hour, providing a uniform release of gas during the decomposition of azodicarbamide, allows to increase the surface and the activity of the sorbent and thereby increase the degree of purification of gases.
Пример 1, Прокаленную окисноцинковую массу смешивахрт с 12,5 вес.% азодккарбамида . К смеси добавл ют 0,5% графита . Смешение провод т в плужном месителе в течение 40 мин при одновременном увлажнении до 5%. Полученную массу таблегируют на габлегмашине. Стебле тир ованный сорбент прокаливают при 250°С при скорости подъема температуры 5°G в час. Полученный сорбент обладает сероемкостью 32%Example 1, a calcined oxide-zinc mass of mixes wax with 12.5 wt.% Of azod-carbamide. 0.5% graphite is added to the mixture. Mixing is carried out in a plow mixer for 40 minutes while moistening up to 5%. The resulting mass is tabled on a gabgle machine. The stem of the coated sorbent is calcined at 250 ° C at a rate of temperature rise of 5 ° G per hour. The resulting sorbent has a sulfur content of 32%
П р и м е р 2. Прокаленную окисноцинковую массу смешивают с 25% азодикарбамида . К смеси добавл ют высокоглиноземистый цемент в количестве 15% и массу увлажн ют до 30%. Полученную массуPRI mme R 2. The calcined oxide-zinc mass is mixed with 25% azodicarbamide. High-alumina cement is added to the mixture in an amount of 15% and the mass is moistened to 30%. The resulting mass
экструдируют не пресс- шнеке. Сформованные гранулы пров ливают в течение 8 ч. при 20°С и прокаливают при 4ОО°С, осуще-ствл подъем температуры со скоростью в час. Полученный сорбент обладает сероемкостью 34-5 вес,%.Extruded not press auger. The formed granules are held for 8 hours at 20 ° С and calcined at 4OO ° С, the temperature rises at a rate of an hour. The resulting sorbent has a sulfur content of 34-5 wt.%.
