Description
Изобретение относится к способам очистки от ацетона смесей токсичных паров и газов с воздухом и может использоваться для удаления ацето- на из отходящих газов промышленных предприятий, использующих кислородсодержащие органические соединения в качестве основного сырья для синтеза полимеров, лаков, лекарственных препаратов и других, а также может быть использовано для решения общей проблемы очистки воздушного бассейна.The invention relates to methods for purification from acetone of mixtures of toxic vapors and gases with air and can be used to remove acetone from exhaust gases of industrial enterprises using oxygen-containing organic compounds as the main raw material for the synthesis of polymers, varnishes, drugs and others, and can also be used to solve the general problem of cleaning the air basin.
Известен способ гетерогенного глубокого каталитического окисления па- 15 ров ряда килородсодержащих производных углеводородов, в том числе ацетона [1].A known method of heterogeneous deep catalytic oxidation of vapors of a series of 15 kylorinated derivatives of hydrocarbons, including acetone [1].
Известен способ удаления ацетона из паро-воздушной смеси путем 20 глубокого окисления его (до СОг и Н2О) на палладиевом катализаторе, содержащем палладиевую чернь на носителе активной окиси алюминия при повышенной температуре [2]. *5A known method of removing acetone from a vapor-air mixture by 20 deep oxidation of it (to CO g and H 2 O) on a palladium catalyst containing palladium black on a carrier of active alumina at elevated temperature [2]. *5
Способ заключается в пропусканий ацетоново-воздушной смеси через слой катализатора при исходной концентрации ацетона 0,01 — 0,07 мг/л, скорости паро-воздушного потока 0,6 и 30The method consists in passing an acetone-air mixture through a catalyst bed at an initial concentration of acetone of 0.01-0.07 mg / L, a steam-air flow rate of 0.6 and 30

Недостатком такого способа является высокая стоимость применяемого катализатора, сам факт необходимости использования при синтезе катализатора - соли драгоценного металла.The disadvantage of this method is the high cost of the catalyst used, the fact of the necessity of using a precious metal salt in the synthesis of the catalyst.
Цель изобретения - удешевление способа очистки паро-воздушной смеси от ацетона при сохранении максимальной степени очистки и исключение необходимости использовать при очистке соль драгоценного металла.The purpose of the invention is to reduce the cost of cleaning the vapor-air mixture from acetone while maintaining the maximum degree of purification and eliminating the need to use precious metal salt when cleaning.
Это достигается тем, что процесс ведут на активной окиси алюминия, модифицированной медью и никелем.This is achieved by the fact that the process is conducted on active alumina modified with copper and nickel.
Пример. Катализатор получают обработкой в статистических уело*· виях при комнатной температуре основы — активной окиси алюминия, марки А—1, фракции 1 — 2 мм раствором аммиаката никеля при последующем взаимодействии полученного промежуточного продукта с раствором аммиа-. ката меди.Example. The catalyst is obtained by treating in statistical conditions at room temperature a base — active alumina, grade A — 1, fraction 1–2 mm in nickel ammonia solution in the subsequent reaction of the obtained intermediate product with ammonia solution. kata copper.

Концентрацию ацетона определяют хроматографическим методом. В данных условиях смесь очищается от ацетона практически Нацело (Спрое= 0,001 мг/л). Степень окисления при 150°с составлюет 100%.The concentration of acetone is determined by chromatographic method. Under these conditions, the mixture is almost completely cleared of acetone (With pro = 0.001 mg / l). The oxidation state at 150 ° C is 100%.
