| 摘 要： | 在酸性介质中铁离子对煤浆电化学氧化动力学影响的分析,表明煤是由Fe~(3+)催化氧化的,且还原而成的Fe~(2+)在阳板上又氧化生成Fe~(3+)。推导出煤浆液中固体颗粒电氧化的数学模型。在含有Fe~(2+)的酸性煤浆中,用此模型计算了煤氧化化学步骤的速度常数。

| Abstract: | This paper discusses the influence of iron ion on the electrochemical oxidation of coal slurries in acidic system. Both kinetic and analytical results support the inference that the mechanism of the catalytic oxidation of coal slurries by Fe~3+ in solution, followed by the oxidation of reduced Fe~2+ at the anode. A mathematical model is presented to describe the heterogeneous electroxidation of a suspended solid particle. This model is applied to the electrolysis of the acidic coal slurries containing dissolved Fe~2+, and the chemical rate constant of coal oxidation is calculated according to this model. |
