Description
Известен способ получени кристаллического адсорбента гидротермальной кристаллизацией гидрогел , полученного смешиванием щелочного раствора алюмината натри с раствором силиката натри .A known method for producing a crystalline adsorbent by hydrothermal crystallization of a hydrogel is obtained by mixing an alkaline solution of sodium aluminate with a solution of sodium silicate.
Предлагаемый способ .позвол ет получить широкопористый адсорбент с радиусом пор больше 5А.The proposed method allows obtaining a wide-porous adsorbent with a pore radius greater than 5A.
Адсорбент может быть использован в промышленности дл глубокого извлечени нефт ных паров из газовых и воздушных потоков, а также в аналитической практике дл адсорбционного разделени углеводородных смесей. Кристаллический адсорбент получают гидротермальной кристаллизацией гидрогел , в котором мол рное отношение SiOjiAbOg равно 2,1-гЗ. Получение такого гидрогел осушествл юг смешиванием щелочного раствора алюмината натри с модулем 1,7 и водного раствора силиката натри (жидкого стекла) с модулем 8. После кристаллизации полученные кристаллы промывают водой до удалени избытка щелочи и высушивают. Адсорбционный объем образца адсорбента составл ет 0,3 . После высушивани при температуре 300-400° адсорбент способен поглощать изооктан, гексан, гептан, бензол , другие нефт ные углеводороды и воду при весьма низких их концентраци х в газовой фазе.The adsorbent can be used in industry for deep extraction of oil vapor from gas and air streams, as well as in analytical practice for the adsorption separation of hydrocarbon mixtures. The crystalline adsorbent is obtained by hydrothermal crystallization of a hydrogel, in which the molar ratio of SiOjiAbOg is 2,1-h3. The preparation of such a hydrogel was made by mixing an alkaline solution of sodium aluminate with a modulus of 1.7 and an aqueous solution of sodium silicate (liquid glass) with module 8. After crystallization, the crystals obtained are washed with water to remove excess alkali and dried. The adsorption volume of the adsorbent sample is 0.3. After drying at a temperature of 300-400 ° C, the adsorbent is able to absorb isooctane, hexane, heptane, benzene, and other petroleum hydrocarbons and water at very low concentrations in the gas phase.
По внешнему виду адсорбент представл ет собою кристаллический порошок с размером кристаллов около одного микрона. Гранулирование адсорбента производ т таблетированием его с добавкой 5-10% глины в качестве св зующего вещества.In appearance, the adsorbent is a crystalline powder with a crystal size of about one micron. The granulation of the adsorbent is carried out by tabletting it with the addition of 5-10% clay as a binder.
