摘要
利用双反应器进行了低电压下电解制氢及煤化学脱硫的研究。该系统由电化学反应器和煤化学脱硫反应器两部分组成。考察了不同参数对电解过程及煤化学脱硫过程的影响情况,并初步研究了双反应器的循环配合问题。结果表明,采用双反应器形式在较低电压(1.0V)下电解制氢,可制得高纯氢气,产氢电流效率为97％左右,每生产1Nm^3H_2耗电2.4W·h,同时能在一定程度上脱除煤中的各种含硫化合物。煤脱硫滤液电解与电解液再脱硫的循环配合较好,使循环操作可较平稳进行。
Pair reactors of an electrochemical reactor and an chemicaldesulfurization reactor were used to study the electrolytic hydrogen production at a low voltage and the chemical desulfurization of coal.The effects of several parameters on the electrolytic process and coal desulfurization were investigated.The combination on the two reactions into a cyclic process was also studied.The results indicated that the process can be realized for the production of pure hydrogen at an electrical voltage approximately one-half that used for generating H2 by ordinary electrolysis of water.The current efficiency for H2 production is about 97% and the power consumption is 2.4kW h/Nm3H2 Various sulfur-containing components in coal were removed in the desulfurization reactor to some extent.In this system,the cyclic process between the electrochemical reactor and the chemical desulfurization reactor was carried out stably.
