Description
Применение сульфоугл , полученного из древесины, в качестве сорбента известно.The use of sulfonated, obtained from wood, as a sorbent is known.
Предлагаемый способ отличаетс тем, что позвол ет получить высококачественный сорбент, поддающийс восстановлению и замен ющий в растворах катионы кальци или магни на ионы натри или водорода .The proposed method is characterized in that it allows to obtain a high-quality sorbent that can be reduced and replaces the calcium or magnesium cations with sodium or hydrogen ions in solutions.
Техника изготовлени сульфоугл из древесины опилок и применени его заключаетс в следующем.The technique of making sulfo angle from sawdust wood and applying it is as follows.
Древесные опилки, высущенные ,до 8-10% содержани влаги и освобожденные от примесей, загружают в реактор, где обрабатывают концентрированной серной кислотой (уд. в. 1,84) при соотношении 7-7,5 весовых частей кислоты на одну часть опилок (4 л. кислоты на 1 кг опилок). Смесь перемешивают в продолжение часа, а затем полученный сульфоуголь отмывают от кислоты .Sawdust, dried up to 8-10% moisture content and free from impurities, is loaded into the reactor, where it is treated with concentrated sulfuric acid (sp. 1.84) at a ratio of 7-7.5 weight parts of acid to one part sawdust ( 4 liters of acid per 1 kg of sawdust). The mixture is stirred for an hour, and then the resulting sulfonated coal is washed from the acid.
Дальнейшую обработку ведут в зависимости от применени : однопроцентным раствором H2SO4 (при применении угл в качестве П-обменника ) или дес типроцентнымFurther processing is carried out depending on the application: a one-percent solution of H2SO4 (when using coal as a P-exchanger) or a percentage percentage

раствором NaCl (при применении в качестве Na-обменника).NaCl solution (when used as a Na-exchanger).
Если сорбент подлежит хранению или транспортировке, то его следует высушить.If the sorbent is to be stored or transported, it should be dried.
Применение сульфоугл , полученного из древесных опилок, может производитьс либо путем фильтровани через него растворов, либо путем смешивани его с растворами при нагревании и отфильтровывани через фильтр-прессы.The use of a sulfo-coal obtained from sawdust can be made either by filtering solutions through it, or by mixing it with solutions when heated and filtering through filter presses.
Дозировка сульфоугл зависит от содержани удал емых солей, консистенции и окрашенности растворов .The dosage of sulfonate depends on the content of salts to be removed, the consistency and color of the solutions.
Регенерацию сульфоугл производ т однопроцентным раствором IbSOi (в случае П-обменника) илл дес типроцентным раствором NaCl (в случае Na-обмечника).Sulfur coal is regenerated using a 1% IbSOi solution (in the case of a P-exchanger) or a 10% NaCl solution (in the case of a Na-striker).
Предмет изобретени Subject invention
Способ получени эффективного сорбента из древесных опилок путем обработки серной кислотой, о тл и ч а ю щ и и с тем, что сульфирование ведут 7-7,5 весовыми част ми серной кислоты уд. в. 1,84 на 1 весовую часть опилок.The method of obtaining an effective sorbent from sawdust by treating it with sulfuric acid, about tl and h, and so that the sulfonation is 7-7.5 weight parts of sulfuric acid beats. at. 1.84 to 1 weight of sawdust.
