摘要：

Separation process of gaseous impurities from hydrogen gas by the known pressure swing adsorption method uses a holding column of the feed-in/feed-out sequence retaining type and at least three adsorption columns containing adsorbents. Each adsorption column is pressurized and depressurized in cycle to repeat adsorption and desorption, during which the holding column is used as an intermediate gas reservoir so that the efficiency of the separation of the impurity can be improved. In this invention, at least one of the following structures is used as the holding column:

j) at least one row of spaces divided by partition walls and arranged in series;
k) at least one hollow body; and
l) at least one row of divided compartments arranged in series.

摘要（中）：

通过已知的变压吸附方法从氢气中分离出气态杂质的方法使用保持柱的进料/进料顺序保持型和至少三个含有吸附剂的吸附塔。 每个吸附塔循环加压和减压以重复吸附和解吸，其中保持塔用作中间气体储存器，从而可以提高杂质分离的效率。 在本发明中，使用以下结构中的至少一个作为保持柱：j）至少一排由分隔壁分隔并且串联排列的空间; k）至少一个中空体; 和l）串联布置的至少一排分隔的隔室。
