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/. Webcoal slurries to commercially useful products was first proposed by Coughlin and Farooque in 1979 [5-8]. It was indicated from their results that Fe 3+ ions, which are released from …
