载钯硅藻土分离柱被广泛应用于TCAP工艺中,以实现氢同位素气体的分离。为优化填充柱分离特性和分离工艺参数,需深入研究填充柱参数对压降的影响。本文研究了内径分别为φ3.0 mm、φ4.0 mm、φ8.0 mm填充柱的压降特性(载钯量56.0%,颗粒度40~60目,松状密度1.10~1.17 g/cm~3,柱长分别为320、560和1 200 mm)。实验测定了分离柱压降特性与Pd/K材料理化性能(粒
Palladium diatomaceous earth separation column is widely used in TCAP process, in order to achieve the separation of hydrogen isotope gases. In order to optimize the column separation characteristics and separation process parameters, in-depth study of the column pressure on the pressure drop. In this paper, the pressure drop characteristics of the packed column with internal diameters of φ3.0 mm, φ4.0 mm and φ8.0 mm were investigated (Pd loading 56.0%, particle size 40-60 mesh, bulk density 1.10-1.17 g / cm ~ 3, with column lengths of 320, 560 and 1200 mm, respectively). The pressure drop characteristics of separation column and the physical and chemical properties of Pd / K material were measured experimentally
