摘要: 以四丁基溴化铵作支持电解质电化学还原煤及其含氧基团模拟物,用甲醇萃取电化学还原前后的煤.还原产物和萃取物由气相色谱-质谱联用仪定性分析,煤含氧基团模拟物的电还原产物用气相色谱定量分析.结果表明,经电化学还原后,煤表面含氧基团减少,需进一步提高煤含氧基团模拟物的转化率.电化学测试同时给出还原过程中各相关电极反应的动力学方程.

关键词: 煤, 煤含氧基团模拟物, 电化学还原

Abstract: Electrochemical reduction of coals and the oxygenic functional simulacrums of coals has been studied.In this process,tetrabutylammonium was used as supporting electrolyte.The coal and the deoxidized coal were extracted by methanol.Qualitative analysis of the deoxidized products and the extractives was carried out on gas chromatograph-mass spectrometer.The deoxidized products of the oxygenic functional simulacrums of coals were analysed quantitatively with gas chromatograph spectrometer.The results show that the oxygenic functional groups on the coals surface decrease and the translation ratios of the oxygenic functional simulacrums of coals need further increase after electrochemical reduction,.The electrochemical tests show simultaneously the kinetics equations of every related electrode reactions during the reduction.

Key words: coals, the oxygenic functional simulacrums of coals, electrochemical reduction
