On the electrolysis of coal slurries
WebOxidation of a coal slurry solution at platinum electrodes in strong acidic media has been studied in detail. The results indicate that the iron ions leached out from coal are responsible for major anodic currents. The Fe (II) is electrolytically oxidized to Fe (III) at the anode, which oxidizes coal to various products including CO/sub 2/. Web1 de ago. de 1981 · Coughlin and Farooque observed that coal electrolysis occurs at 0.7–0.9 V, which is close to the theoretical potential of Fe2+. Subsequent studies [19–22] …
