Description
Dotychczasowe metody wytwarzania ksztaltowanego wegla aktywnego opieraja sie na uzyciu lepiszcza, np, smoly pogazo¬ wej, smoly drzewnej, cial humusowych i t d. Pyl weglowy miesza sie z lepiszczem, podsusza, a nastepnie aktywuje w wyzszych temperaturach. Sposoby te wykazuja te wa¬ de, ze lepiszcze, jako materjal czesciowo zweglony, bez zachowania warunków odpo¬ wiednich jest trudno aktywowac, co, oczy¬ wiscie, wplywa na jakosc wegla aktywnego.Jezeli zas do ksztaltowania uzyc pylu z we¬ gla aktywnego, to lepiszcze zakrywa pory wegla aktywnego przy wypalaniu i akty¬ wacji i, dajac materjal gorszy, obniza ja¬ kosc uzytego wegla aktywnego.Sposób wedlug wynalazku usuwa te bra¬ ki. Materjal, sluzacy jako lepiszcze, od sa¬ mego poczatku juz od najnizszych tempe¬ ratur znajduje sie w warunkach, sprzyja¬ jacych rozbudowie wewnetrznej powierzch¬ ni swobodnej, tak waznej dla wegla aktyw¬ nego. Sposób pracy umozliwia kontrole nad tworzeniem sie w weglu aktywnym ka¬ nalików odpowiedniej srednicy. Srednica tych kanalików (por) ma wazne znaczenie, *) Wlasciciel patentu oswiadczyl, ze wynalazca jest Feliks Polak w Warszawie.gdyz wplywa na szybkosc pochlaniania oraz na latwosc wnikania ciala, pochlania¬ nego wewnatrz ziarna weglowego.Jako lepiszcza w sposobie niniejszym uzywa sie weglowodanów, np. skrobi, me¬ lasy i innych odpadków technicznych. Le¬ piszcze w obecnosci soli mineralnych, cia¬ gle mieszajac, ogrzewa sie w temperaturach 100 — 200°C, az do wytworzenia sie masy zelatynowatej. Mase te podsusza sie ostroz¬ nie az do uzyskania przez nia odpowiedniej plastycznosci. Nastepnie do masy plastycz¬ nej dodaje sie pylu weglowego, rozprowa¬ dzajac go w masie Jak najdokladniej, po- czem wyrabia sie okreslone ksztaltki w spo¬ sób znany. Wielkosc i ksztalt geometryczny wegla aktywnego zalezy tylko od przezna¬ czenia.Przy wytwarzaniu masy plastycznej u- trzymuje sie w masie odpowiednia kwaso¬ wosc p H= 4—5 przez dodanie do masy kwasów mineralnych lub organicznych.Po wytworzeniu ksztaltek, wypala sie je w temp. 400 — 700°C, luguje z nich sub¬ stancje mineralne, których mozna uzyc po¬ wtórnie, PLPrevious methods for the production of shaped activated carbon are based on the use of a binder, for example, coal tar, wood tar, humic bodies, etc. The coal dust is mixed with the binder, dried and then activated at higher temperatures. These methods show also the disadvantages that the binder, as a partially charred material, is difficult to activate without maintaining the appropriate conditions, which, of course, affects the quality of activated carbon. If you use activated carbon dust to shape, this binder covers the pores of the activated carbon in firing and activation and, giving an inferior material, reduces the quality of the activated carbon used. The method according to the invention removes these deficiencies. The material, which serves as a binder, from the very beginning, from the lowest temperatures, is under conditions conducive to the expansion of the internal free surface, so important for activated carbon. The method of operation makes it possible to control the formation in the activated carbon of stones of the appropriate diameter. The diameter of these channels (por) is important, *) The patent owner stated that the inventor is Feliks Polak in Warsaw, because it affects the absorption speed and the ease of body penetration, absorbed inside the carbon grain. As a binder in this method, carbohydrates are used for example starch, metal and other technical scrap. Mucilage in the presence of mineral salts, while stirring with constant stirring, is heated at temperatures of 100 - 200 ° C until a gelatinous mass is formed. These masses are carefully dried until they obtain the required plasticity. Coal dust is then added to the plastic mass, distributing it throughout the mass as accurately as possible, and then the specific shapes are made in a known manner. The size and geometric shape of the activated carbon depends only on the intended use. During the preparation of the plastic mass, the appropriate acidity p H = 4-5 is maintained in the mass by adding mineral or organic acids to the mass. After forming the shapes, they are burned to temperature 400-700 ° C, they leach mineral substances that can be reused, PL
