Description
Dotychczasowe patenty w niewielkim jedynie stopniu uwzglednialy wegiel ka¬ mienny, jako produkt wyjsciowy do otrzy¬ mywania wegli wysokoaktywnych, pomimo, ze jest to produkt tani i znajdujacy sie w wielkiej ilosci. Zwlaszcza niechetnie uzy¬ wano wegli starszych formacyj, Autorzy nielicznych patentów, uwzgledniajacych we¬ giel kamienny, proponowali przewaznie badz to uprzednia ekstrakcje wegla zapo- moca chemikalij, np. tetraliny, celem po¬ zbycia sie substancyj bitumicznych zakle¬ jajacych pory wegla, badz tez aktywacje przy uzyciu srodków impregnujacych.Wedlug niniejszego wynalazku, wegiel aktywny moze byc otrzymany z wszelkiego rodzaju wegla pochodzenia kopalnego: an¬ tracytu, wegli kamiennych koksujacych i niekoksujacych, lignitów i t. p, bez stosowa¬ nia odczynników w stanie cieklym lub sta¬ lym, przy zachowaniu jednak nastepuja¬ cych warunków: 1- aby rozdrobnienie wegla bylo znaczne, np. 800 oczek na cm2, 2. aby ogrzewanie w granicach temperatur, odpo¬ wiadajacych stanowi plastycznemu danego wegla, bylo bardzo powolne (maksymalna szybkosc ogrzewania nie powinna przekra¬ czac l°/mm). Nastepnie wegiel ogrzany zostaje do temperatury nie nizszej niz 850°C i utrzymany w tej temperaturze przez szereg godzin.Do aktywacji uzyte byc moga pary lub gazy aktywujace.Materjal w ten sposób uzyskany mozebyc nastepnie poddany dzialaniu chemika' lij, np. kwasów, zasad i t. p., plókany, roz¬ drobniony i suszony. Otrzymany ta droga wegiel odznacza sie wysokiemi wlasnoscia¬ mi adsorbcyjnemi. PLPrevious patents only to a small extent included hard coal as a starting product for obtaining high-level carbon, despite the fact that it is a cheap and abundant product. In particular, coal of older formations was reluctantly used. The authors of a few patents, including hard coal, usually proposed a prior extraction of the coal with a chemical, e.g. tetralin, in order to obtain bituminous substances blocking the pores of coal, or Activation with impregnating agents. According to the present invention, activated carbon can be obtained from all kinds of fossil-derived carbon: anthracite, coking and non-coking coal, lignites, etc., without the use of liquid or solid reagents however, under the following conditions: 1 - the fragmentation of the coal was significant, e.g. 800 mesh per cm 2, 2. ¬ incl. 1 ° / mm). The coal is then heated to a temperature of not less than 850 ° C and kept at this temperature for several hours. Activating vapors or activating gases can be used for activation. The material thus obtained can then be treated with a chemical, e.g. rt, fluffed, ground and dried. The carbon obtained in this way is distinguished by high adsorption properties. PL
