摘要
研究了Ｈ＿２和ＣＯ在ＣｕＯ－ＺｎＯ＿Ａｌ＿２Ｏ＿３催化床中转化成Ｈ＿２Ｏ和ＣＯ＿２的实验装置和实验结果，论证了不同床层工作温度、系统压力、杂质浓度、流量及露点温度等因素对氧化铜床工作性能的影响；测得了Ｈ＿２和ＣＯ在ＣｕＯ－ＺｎＯ－Ａｌ＿２Ｏ＿３床上的转化特性曲线等变化规律，获得了转化容量、工作周期和转化效率等实验数据，确定了最佳运行参数。结果表明，使用ＣｕＯ＿ＺｎＯ－Ａｌ＿２Ｏ＿３床可使净化后的Ｈ＿２和ＣＯ的体积分数都小于２×ｌ０￣（－６），满足高温气冷堆的净化要求。为高温气冷堆中氧化铜床装置提供了可靠的设计数据。
The conversions of hydrogen and carbn monoxide into water vapor and carbod dioxide onCuO-ZnO-Al_2O_3 catalyst are studied. The effects of different temperature, system atmosphericpressure, impurity gas concentration, flow and dew point on properties of cupric oxide bed areinvestigated. The conversion characteristics curves of H_2 and CO are given. Experimental data ofconversion capacity, action period and conversion efticiency of CuO-ZnO-Al_2O_3 are obtained andthe optimal parameters are determined. The results show that the concentration of H_2 and CO ofthe effluent gas after purification can reach below 2 × 10￣(-6), respectively. So it can meet the de-mands of high temperature gas-cooled reactor and also provied optimal design parameters and reli-able data for conversion of H_2 and CO on CuO-ZnO-Al_2O-3 catalyst.
