Description

Verfahren zur Herstellung von Elektroden aus Braunkohle. In früheren Patenten hat die Erfinderin vorgeschlagen, bei der Herstellung von Elektrodenkohlen Braunkohle als Ausgangsmater:al zu verwenden. In der Praxis hat sich herausgestellt, daß man, um Elektroden aus verkokter Braunkohle herzustellen, die Bindemittel, wie Teer oder Pech, in großer Menge anwenden muß. Dieser große Zusatz von Teer oder Pech verteuert natürlich die Herstellung der Kohlen und hat einen nachteiligen Einfluß auf ihre Haltbarkeit.' Eingehende Versuche haben nun das überraschende Resultat ergeben, daß, wenn man die Braunkohle vor dem Verkoken brikettiert, der erhaltene dichte Koks zur Bindung zwecks Herstellung von Elektroden nur etwa die Hälfte des Bindemittels benötigt, als wenn man Koks verwendet, der aus nichtbrikettierter Braunkohle leergestellt ist. Elektroden aus derartigem Braunkohlenkoks sind von guter Beschaffenheit.Process for the production of electrodes from lignite. In earlier The inventor has proposed patents for the production of electrode carbons Lignite as a starting material: al to be used. In practice it has been found that in order to produce electrodes from coked lignite, the binders, such as Tar or pitch, must be used in large quantities. This great addition of tar or Of course, pitch makes the production of the coals more expensive and has a detrimental effect on their durability. ' In-depth experiments have now the surprising result show that if the lignite is briquetted before coking, the obtained dense coke for binding for the purpose of making electrodes only about half of the As if using coke made from non-briquetted lignite is empty. Electrodes made from such lignite coke are of good quality.

Das Wesentliche dieser Erfindung besteht darin, daß die erforderliche Dichtigkeit des Braunkohlenkokses für die Darstellung haltbarer Elektroden, die nicht durch alleiniges Glühen zu erreichen ist, dadurch erhalten wird, daß man die Braunkohle vor ihrer Verkokung einem - zweckmäßig möglichst hohen - Druck aussetzt.The essence of this invention is that the required Lignite coke tightness for the representation of durable electrodes that cannot be achieved by annealing alone, is obtained by the Exposing lignite to a - appropriately as high as possible - pressure before coking.
