分子筛填充的低温分子筛床(CMSB)将应用于聚变堆固态氚增殖包层氚回收系统(TES),主要作用是在低温条件下将氘氚燃料循环工艺氦气混合气体中的微量氢同位素(氚)提取回收。本文以获得评价分子筛性能及设计CMSB所需的吸附平衡数据为目标,在77 K液氮温度、10~103 Pa低压、纯H2下开展了5A分子筛(MS5A)的H2吸附等温线实验。研究结果表明,碱化处理(NaOH碱溶液浸泡处理)
Molecular sieve packed cryogenic molecular sieve bed (CMSB) will be used in the fusion reactor solid tritium enrichment tritium tritium recovery system (TES), the main role is to be in the low temperature conditions of deuterium and tritium fuel cycle process helium mixed gas trace hydrogen isotopes (tritium ) Extraction and recovery. In this paper, H2 adsorption isotherm experiments of 5A molecular sieve (MS5A) were carried out at 77 K liquid nitrogen temperature, 10 ~ 103 Pa low pressure and pure H2 to get the molecular sieve performance and the adsorption equilibrium data needed to design CMSB. The results show that alkalization (NaOH alkaline solution soaking treatment)
