Patent number: 11015869Abstract: A method for reducing molten raw materials, includes placing the raw materials, in a solid or molten state, on an inductively heated bed with coke pieces. The reduced melt that runs off the coke bed is collected and the waste gases are discharged. A coke bed is inwardly limited by a tube-shaped element through which the reaction gases are drawn off via a plurality of draw-off openings in the tube-shaped element. The corresponding device has a reactor for a bed with coke pieces and an induction heater with at least one induction coil. The reactor has a loading opening and a discharge opening for the treated melt. The coke bed is ring-shaped around a tube-shaped element. The material of the tube-shaped element allows inductive coupling to the induction field of the induction coil and it has draw-off openings for drawing off reaction gases from the coke bed.Type: GrantFiled: November 24, 2015Date of Patent: May 25, 2021Assignee: SHOWA DENKO CARBON Germany GmbHInventors: Alfred Edlinger, Daniel Steppich

Patent number: 9199109Abstract: In a method for processing used cathode material containing carbon, in particular used cathode troughs from aluminum production, the cathode material is put into a shaft furnace and, in order to gasify carbon, is subjected to a thermal treatment in the shaft furnace at a temperature above the ignition temperature of the carbon and above the evaporation temperature of toxic substances contained in the used cathode material. The reaction gases are conducted co-current with the carbon in a first longitudinal section of the shaft furnace and countercurrent to the carbon in a second longitudinal section of the shaft furnace. The reaction gases are drawn from a region of the shaft furnace having an enlarged cross-section between the longitudinal sections and are preferably subjected to an after-treatment.Type: GrantFiled: August 23, 2013Date of Patent: December 1, 2015Assignee: SGL CARBON SEInventors: Alfred Edlinger, Johann Daimer
