ALUMINUM-PRODUCING ELECTROLYZER, ANODE PACK OF ELECTROLYZER, METHOD OF REARRANGING ELECTROLYZER, AND METHOD OF ALUMINUM PRODUCTION Russian patent published in 1998 - IPC

FIELD: aluminum production. SUBSTANCE: invention relates to production of aluminum from silica dissolved in liquid salt electrolyte. In electrolyzer containing multitude of nearly vertical anodes and cathodes made of electron-conductance material resistant to electrolyte and electrolysis products, cathodes are disposed inside surrounding them anodes or tubular anodes in such a way that active surface of cathode faces inside active surface of anodes. Anodes and cathodes are combined into blocks parallel to powered electrodes and at least one anode has at least one port in its upper part to discharge oxygen released on anode. EFFECT: improved structure and enhanced efficiency of electrolysis. 24 cl, 13 dwg , 1 tbl
