| 摘 要： | 采用程序升温脱附法在自行研制的大型气相色谱柱上进行了氢同位素的分离,包括氕-氘体系的半饱和实验、全饱和实验和低丰度样品的浓缩实验。实验结果表明该分离方法分离效率高、处理容量大。氘浓度为0.1%的样品混合气经色谱柱分离后得到氘浓度为30%的产品,贫化部分氘浓度小于10-5;氘浓度为10%的样品混合气分离后得到氘浓度大于90%的产品;对氕-氘混合气的处理容量达到70m3/d。

| Abstract: | A series of hydrogen isotope separation experiments using temperature programmed desorption were carried out with chromatographic column,including half-saturation test,saturation test and enrichment test with low abundance samples.Experimental results show that the separation method using temperature programmed desorption enjoys high separation efficiency and big treatment capacity.The abundance ratio of D/H mixed gases reaches 30% from 0.1%,and more than 90% from 10%,the ratio is less than 10-5 in the depleted gas.The treated capacity reaches 70 m3/d. |
