Description
Przy rafinacji wegla wywarowego i po¬ dobnych produktów na potaz i sole pota¬ sowe pozostaje bardzo rozdrobniony we¬ giel, który przez absorbcje zatrzymuje w so¬ bie az do 30% ze swego ciezaru soli lekkich alkaljów. Metodami dotychczas stoso- wanemi, wedlug których uzywa sie rozczy- nów alkalicznych, nie mozna uzyskac tej reszty soli wskutek wielkiej absorbcji, ja¬ ka posiada bardzo rozdrobniony wegiel w takich rozczynach.Ten nowy sposób pozwala otrzymywac te reszte soli przez zastosowanie odpowied¬ nio zakwaszonego rozczynu, w którym si¬ la absorbcyjna bardzo rozdrobnionego we¬ gla nadzwyczajnie sie zmniejsza. W tym celu mieszanine soli alkalicznej z weglem, która przy zwykle uzywanym rozczynie alkalicznym pozostaje jako niepozadany produkt odpadkowy, zakwasza sie kwasa¬ mi, które dobiera sie zaleznie od soli, za¬ danej jako produkt ostateczny. W danym razie dodaje sie ilosc wody, potrzebna do dalszego przerabiania soli, lub tez innego srodka rozcienczajacego, wpierw, równo¬ czesnie z kwasem lub tez pózniej. Tem¬ peratury reakcji dobiera sie równiez od¬ powiednio do dalszego przerabiania soli.Nastepnie oddziela sie rozczyn soli od we¬ gla i rafinuje az do pozadanego stopnia- Takze wegiel, otrzymywany jako produkt uboczny, mozna przez poddanie go dzia¬ laniu swiezych kwasów rafinowac az do zadanego stopnia czystosci, przyczem moz¬ na uzywac tych kwasów do stosownego ra¬ finowania mniej czystego wegla, a nako-niec do zakwaszania mieszaniny wegla z sola alkaliczna, jako swiezym materjalem, od którego sie znowu zaczyna. PLIn the refining of coal and similar products into potassium and potassium salts, a finely divided coal remains, which by absorption retains up to 30% of its weight of light alkali salts. By the methods used hitherto, which use alkaline solutions, it is not possible to obtain this salt residue due to the great absorption, as it has a finely divided carbon in such solutions. This new method allows to obtain these salt residues by using an appropriately acidified a solution in which the absorption power of finely divided coal is remarkably reduced. For this purpose, the mixture of alkali salt with carbon, which remains as an undesirable waste product with the usual alkaline solution, is acidified with acids, which are chosen according to the salt selected as the final product. If necessary, the amount of water needed for the further processing of the salt or any other diluting agent is added first, simultaneously with the acid or thereafter. Reaction temperatures are also selected in accordance with the further processing of the salt. The salt solution is then separated from the coal and refined to the desired degree. Also the carbon obtained as a by-product can be refined by treating it with fresh acids. to the desired degree of purity, by which these acids can be used to adequately refine the less pure carbon and to cause acidification of the mixture of carbon and alkali salt as a fresh material from which to start again.
