- The experimental studies on hydrogen isotopic deuterium from gas to liquid phase were completed by mixed ratio 1 ∶ 4 of Pt-SDB hydrophobic catalyst and hydrophillic packing. The influencing factors on number of transfer units ( NTU) and transformation efficiencies of deuterium were researched.
采用PtSDB疏水催化剂与亲水填料按1∶4混装进行氘从气相到液相的催化交换实验，研究影响传质单元数及氘转化率的因素。
