| 摘 要： | 采用伏安法对六种煤浆的电解氧化特性进行研究,考察了煤种、铁离子溶液催化剂、温度和搅拌速度对氧化电流密度的影响。结果表明,温度、电压和转速的增加可以提高其氧化电流密度,在室温下加入5 mmol Fe3+,可以使神木煤浆的氧化电流密度提高至18.4 m A/cm2。通过XRD分析可知,电解破坏煤的大分子结构。

Study on Electrochemical Oxidation Characteristics of Coal |

| Abstract: | The electrolytic oxidation characteristics of six kinds of coal slurry were studied by voltammetry. The influence of different electrolytic factors, such as kinds of coal, temperature, voltage, stirring speed and catalysts on oxidized current density was investigated. The results show that oxidized current density enhances with increasing of operational temperature, voltage, and stirring speed. Under room temperature, adding 5 mmol Fe3+ can increase oxidized current density in electro-oxidation of Shenmu bitumite to 18.4 mA/cm2. The XRD characterization proved that electrolysis could break coal macromolecular structure. |
