Abstract
Przedmiotem zgłoszenia jest sposób wytwarzania węgla aktywnego z bawełny przemysłowej, polegający na dodaniu do materiału aktywatora lub jego roztworu, suszeniu otrzymanej mieszaniny, jej karbonizacji w atmosferze gazu obojętnego chemicznie, przemywaniu i suszeniu. Sposób charakteryzuje się tym, że jako aktywator stosuje KOH i/lub Na2CO3 i/lub K2CO3, przy czym miesza się kawałki bawełny przemysłowej z wodnym roztworem aktywatora lub zwilża się materiał i miesza ze stałym aktywatorem w stosunku wagowym 1: 0,1-5, przy czym jako aktywator stosuje się, po czym mieszaninę pozostawia się na czas 0 - 24 godziny. Mieszaninę poddaje się karbonizacji w temperaturze 500 - 1000°C, po ochłodzeniu, otrzymany produkt przemywa się wodą destylowaną do uzyskania odczynu obojętnego, traktuje kwasem solnym i ponownie przemywa wodą destylowaną do odczynu obojętnego i tak otrzymany węgiel aktywny suszy się. Gaz obojętny chemicznie podaje się z prędkością 0,5 - 50 l/h. Jako gaz obojętny chemicznie stosuje się azot lub dowolny gaz szlachetny.The subject of the application is a method of producing activated carbon from industrial cotton, consisting of adding an activator or its solution to the material, drying the resulting mixture, its carbonization in an inert gas atmosphere, washing and drying. The method is characterized in that KOH and / or Na2CO3 and / or K2CO3 are used as the activator, whereby pieces of industrial cotton are mixed with the aqueous activator solution or the material is wetted and mixed with the solid activator in a weight ratio of 1: 0.1-5, wherein the activator is used, after which the mixture is left for 0-24 hours. The mixture is carbonized at 500 - 1000 ° C, after cooling, the product obtained is washed with distilled water until neutral, treated with hydrochloric acid and washed again with distilled water until neutral, and the activated carbon thus dried is dried. Chemically inert gas is fed at a speed of 0.5 - 50 l / h. Nitrogen or any noble gas is used as chemically inert gas.
