摘　　要：ADS不纯氦气回收净化系统中采用椰壳活性炭来吸附氦气中的杂质,不纯氦气中的杂质主要包括氮气、氧气、水、CxHy和少量的氩气、氢气、油蒸汽等。通过实验研究了氮气、氧气、氩气和氢气四组分气体在椰壳活性炭中的动态吸附特性,比较了动态吸附过程中各组分之间的相互影响,通过LRC负载关联式模型对各组分动态吸附量进行了拟合,给出了氦气净化过程中椰壳活性炭用量的计算方法。The coconut activated carbon was used to adsorb the impurities of the impure helium in the Accelerator Driven Sub - critical （ADS） helium purification system. The impurities include nitrogen, oxygen, argon, hydrogen and so on. The dynamic adsorption characteristics of N2/O2/Ar/H2 multi - components through the coconut activated carbon were conducted with experi- ments. The dynamic adsorption isotherms of each component were fitted with Loading - Ratio Correlation （LRC） model. The for- mula used to calculate the mass of activated carbon in helium purification system was presented.
