摘要：

为了探究工业废液对电解煤浆制氢的影响，在电解煤浆制氢体系阳极电解质中添加3种工业废液：洗气水、硫磺水、碳化水，分析废液添加前、后的电流密度-电压曲线，研究废液加入对氢气电流效率和产氢速率的影响以及废液体积分数和搅拌速率对电解电流密度的影响. 结果表明，3种废液不改变煤浆初始电解电位，但影响煤浆电解速率，其中洗气水、硫磺水废液可以有效地增大电流密度，提高电解速率；洗气水废液的加入不改变电解煤浆的氢气电流效率，但随着洗气水体积分数的增大，电流密度呈现先急剧增大再略微降低的趋势；电解废液煤浆速率受搅拌速率的影响，提高搅拌速率使传质增强，电流密度增大.
Abstract:

Three kinds of industrial waste water named Xiqi, Liuhuang and Tanhua were added to the anodic electrolyte of coal slurry electrolysis system in order to analyze the effect of industrial waste water on hydrogen production from coal slurry electrolysis. The current density-voltage curves before and after the addition of waste water were analyzed. Then the effect of waste water addition on current efficiency and hydrogen production rate, and the effect of waste water volume fraction and stirring speed on the electrolytic current density were analyzed. Results show that the three kinds of waste water do not change the initial electrolytic potential of coal slurry electrolysis, but have great influence on the electrolysis rate. Xiqi and Liuhuang waste water can effectively increase the current density and the rate of electrolysis. The addition of the Xiqi waste water has no effect on the hydrogen current efficiency of coal slurry electrolysis, but the current density shows a rapid increase and then a slight decrease with the increase of the volume fraction of the Xiqi waste water. The rate of waste water coal slurry electrolysis is affected by the stirring rate. The mass transfer and the current density both increase with the increase of stirring rate.
