Abstract
Изобретение относитс к регенерации активированного угл и позвол ет повысить степень его регенерации . Уголь используетс дл очистки медьсодержащих растворов в процессе концентрировани бутадиена. Отработанный активированный уголь сначала промывают раствором, содержаи им 5-10% аммиака и 5-10% уксусной кислоты, а затем обрабатьшают паром в присутствии воздуха при 250-275 0. 1 з.п. ф-лы, 2 табл. (W 4 О5 01 елThe invention relates to the regeneration of activated carbon and makes it possible to increase the degree of its regeneration. Coal is used to purify copper-containing solutions in the process of concentrating butadiene. The waste activated carbon is first washed with a solution, containing 5–10% ammonia and 5–10% acetic acid, and then treated with steam in the presence of air at 250–275 0. 1 ° C. f-ly, 2 tab.

Description
Изобретение относитс к способу регенерации активированного угл и может быть использовано в процессе концентрировани бутадиена при помощи медно-аммиачных растворовThe invention relates to a method of regenerating activated carbon and can be used in the process of concentrating butadiene using copper ammonia solutions.
Целью изобретени вл етс повышение степени регенерации активированного угл дл очистки медьсодержащих растворов в процессе концент- рировани бутадиена.The aim of the invention is to increase the degree of regeneration of activated carbon for the purification of copper-containing solutions during the concentration of butadiene.
Пример. Активированный уголь АГ-3, использованньй дл очистки медьсодержащих растворов в процессе концентрировани бутадиена, промываю водным раствором, содержащим аммиак и уксусную кислоту.Example. AG-3 activated carbon used to purify copper-containing solutions in the process of concentrating butadiene is washed with an aqueous solution containing ammonia and acetic acid.
Данные по степени отмывки угл от меди приведены в табл. 1.Data on the degree of washing of coal from copper are given in table. one.
Услови промывки: температура , соотношение уголь-раствор 1:5, врем 2 ч.Washing conditions: temperature, coal-solution ratio 1: 5, time 2 h.
В табл. 2 отражена зависимость . восстановлени адсорбционных свойств отработанного угл от температуры обработки паром в присутствии воз- Духа.In tab. 2 reflects the dependence. recovery of adsorption properties of waste coal from the temperature of steaming in the presence of air.
