Изобретение относитс к способу очистки газов от сернистого ангидрида с применением в качестве адсорбента - вермикулита.The invention relates to a method for the purification of gases from sulfuric anhydride using vermiculite as an adsorbent.
Известен способ очистки дымовых газов от SOa вермикулитом, пропитанным неорганическим реагентом, например, карбонатом патри , перманганатом кали и другими с последующей десорбцией газа. Газ при очистке пропускают через слой увлажненного вермикулита , поглощающего S02.A known method of cleaning flue gases from SOa with vermiculite impregnated with an inorganic reagent, for example, patriotate carbonate, potassium permanganate, and others, followed by desorption of gas. When cleaning gas is passed through a layer of moistened vermiculite, absorbing S02.
Недостатком этого способа вл етс низка степеиь очистки газа от S02, составл юща приблизительно 40-45%.The disadvantage of this method is the low degree of gas purification from S02, amounting to approximately 40-45%.
Предложенный способ отличаетс от известного тем, что в качестве адсорбента дл SO2 используют обработанный 10:%-ной серной кислотой ириродный вермикулит следующего составаThe proposed method differs from the known one in that as the adsorbent for SO2 is used the irivoric vermiculite of the following composition treated with 10:% sulfuric acid
(On)2-(Mg,Fe),Al 4-4H20,(On) 2- (Mg, Fe), Al 4-4H20,
что приводит к увеличению степени очистки до 90-96%, позвол ет повысить термостойкость адсорбента.which leads to an increase in the degree of purification up to 90-96%, allows to increase the heat resistance of the adsorbent.
Пример. В реактор диаметром 18 мм, высотой 150 мм насыпают на решетку с отверсти ми 14,5 г активированного 10%-нойИ2504 вермикулита с размером частиц 1 -1,5 мм следующего составаExample. A reactor with a diameter of 18 mm and a height of 150 mm is poured on a grid with openings of 14.5 g of activated 10% I2504 vermiculite with a particle size of 1 -1.5 mm of the following composition
(ОН)2- (Mg, Fe), А1 4-4Н2О(OH) 2- (Mg, Fe), A1 4-4H2O
Пропускают в течение 130 мин 195 нл газовой смеси при 25°С с начальной концентрацией SO2 0,3 об. %. Степень очистки составл ет 98,6%.195 nl of the gas mixture at 25 ° C with an initial concentration of SO2 0.3 vol. % The degree of purification is 98.6%.
Предмет изобретени Subject invention
Способ очистки газов от SO2 путем адсорбции его природным вермикулитом, обработанным неорганическим реагентом, отличающийс тем, что, с целью повышени стенени очистки , в качестве адсорбента используют обработанный 10%-ной серной кислотой природный вермикулит следующего составаThe method of purification of gases from SO2 by adsorption by its natural vermiculite treated with an inorganic reagent, characterized in that, in order to increase the cleaning wall, the natural vermiculite of the following composition is used as an adsorbent
(OH)2-(Mg,Fe),Al 4-4H20(OH) 2- (Mg, Fe), Al 4-4H20
