Description
Затем через адсорбционную колонку пропускают при паровоздушную смесь (ПВС) с содержанием метилметакрилата (ММА) 35-40 мг;л. Скорость ПВС через слой угл составл ет 0,2 м/се. После адсорбции уголь подвергают регенерации вод ным паром при 100-120°С в течение . 1 ч. Расход пара не превьзшает 5 кг/ рекуперата. По окончании регенерации уголь сушат гор чим воздухом при 110-12о С, охлаждают до и став т на вторичную адсорбцию. Скорость воздуха при сушке составл ет 0,2 м/сек.Then, an adsorption column is passed with an air-steam mixture (PVA) with a content of methyl methacrylate (MMA) of 35-40 mg; l. The PVA velocity through the coal bed is 0.2 m / sec. After adsorption, coal is subjected to steam regeneration at 100–120 ° C for. 1 h. Consumption of steam does not exceed 5 kg / recuperate. At the end of the regeneration, the coal is dried with hot air at 110-12 ° C, cooled before and placed for secondary adsorption. The air velocity during drying is 0.2 m / s.
При подобных услови х опыта в качестве адсорбатов используют, бутилметакрилат (ВМА) и метакриловую кислоту (Г4АК) с концентра;цией 0,114 6,3 мг/л, соответственно. Данные опытов приведены в таблице.Under similar experimental conditions, butyl methacrylate (BMA) and methacrylic acid (G4AK) with a concentration of 0.114 6.3 mg / l, are used as adsorbates. These experiments are shown in the table.
П р. и м е р 2, Адсорбционную колонку ( d 2 см), заполненную активированным углем марки (ве угл 10 г), заливают при 25-30°С водным раствором.ДФП (концентраци раствора 1Ь мг/л) вЪбъемном соотно шении 1:1. После 15-20 мин выдержки воду из колонки сливают, адсорбент Сушат гор чим воздухом при 110 .120°С (скорость воздуха 0,2 м/сек)Etc. and meper 2, an adsorption column (d 2 cm), filled with activated carbon (brand 10 g), is poured at 25-30 ° C with an aqueous solution. DFP (concentration of 1 mg / l solution) in a 1: 1 volume ratio . After 15-20 minutes of aging, the water is drained from the column, the adsorbent is dried with hot air at 110 .120 ° С (air speed 0.2 m / s)
и охлаждают до 25-30 с. Концентраци ДФП в угле составл ет 15010- % от веса адсорбента.and cooled to 25-30 s. The concentration of TPA in coal is 15010% by weight of the adsorbent.
НасЕлцение такого угл мономерами и регенерацию его провод т по методике , описанной в примере № 1. В качестве адсорбента используют ММл, ВМд и МАК с той же концентрацией их в ПВС (см. пример 1.). Результаты опытов приведены в таблице.The carbonation of such carbon with monomers and its regeneration are carried out according to the procedure described in Example No. 1. MML, VMd and MAK are used as adsorbent with the same concentration in PVA (see Example 1.). The results of the experiments are given in the table.
Пример 3. Адсорбционную ко-лонку , заполненную активированным углем марки АР-3 (вес угл 10 г), заливают при 25-30С водным раствором ДФП с концентрацией 30 мг/л вExample 3. An adsorption column filled with activated carbon of the АP-3 brand (weight of coal is 10 g) is poured at 25-30 with an aqueous solution of DFP with a concentration of 30 mg / l in
объемном соотношении 1:1. Содержание ДФП в угле составл ет 30010 % от веса адсорбента.volume ratio of 1: 1. The content of TPP in coal is 30010% by weight of the adsorbent.
Методика насыщени , регенерации, обработки угл и услови их проведени описаны в примере 1. В качестве адсорбатов используют ВМА и МАК с той же концентрацией. Данные опытов Приведены в таблице.The method of saturation, regeneration, processing of coal and the conditions for their conduction are described in Example 1. BMA and MAC are used as adsorbates with the same concentration. These experiments are given in the table.
Как видно из таблицы, присутствиеAs can be seen from the table, the presence
ДФП в угле уменьшает образование полимера на поверхности адсорбента по сравнению с углем, обработанным водным раствором НДФА, в 1,5 раза, что позвол ет увеличить срок службы адсорбента в 1,5 раза.DFP in coal reduces the formation of polymer on the surface of the adsorbent as compared with coal treated with an aqueous solution of NDPA by 1.5 times, which makes it possible to increase the service life of the adsorbent by 1.5 times.
