Description

Verfahren zur Herstellung von Elektrodenkohle. Die Fabrikation der Kohlenelektroden macht erhebliche Schwierigkeiten, weil es an aschearmen Kohlen, z. B. Anthracit und Retortengraphit, mangelt.Process for the production of electrode carbon. The manufacture of the Carbon electrodes cause considerable difficulties because low-ash coals, z. B. anthracite and retort graphite is lacking.

Eingehende Versuche haben nunmehr ein neues Verfahren festgestellt, nach dem ohne zain2 uoA alqoxuapozixal2[ auta ;iax.TZarn@uaS Beschaffenheit- gewonnen werden kann. Für die Fabrikation kommt als Rohstoff huminsäurehaltiges Material, wie Humuskohle, Torf usw., in Betracht.In-depth tests have now identified a new procedure, after the without zain2 uoA alqoxuapozixal2 [auta; iax.TZarn@uaS texture- won can be. The raw material used for production is humic acid-containing material, such as humus coal, peat, etc., into consideration.

Bekanntlich löst sich die Humuskohle, die in ergiebigen Lagern festgestellt worden ist, bis auf einen geringen Rückstand, der dem Aschegehalt entspricht, in Ammoniak- oder Alkalilösung. Die von den Rückständen befreite Humatlösung wird mit Säuren, z. B. Salzsäure, versetzt, wobei die Huminsäuren ausfallen, während die Salze in Lösung bleiben. Die ausgefällten Huminsäuren werden ausgewaschen und dann verkohlt. Man ist hierdurch in der Lage, eine Kohle von beträchtlicher Reinheit zu erhalten, die sich hervorragend als Elektrodenkohle eignet.As is well known, the humus coal, which was found in abundant stores, dissolves has been, except for a small residue, which corresponds to the ash content, in Ammonia or alkali solution. The humate solution freed from the residues is with Acids, e.g. B. hydrochloric acid, added, whereby the humic acids precipitate, while the Salts stay in solution. The precipitated humic acids are washed out and then charred. In this way one is able to obtain a coal of considerable purity to obtain, which is ideally suited as an electrode carbon.
