Adsorbent, adsorption column and apparatus for pressure swing adsorption separation

摘要

There is provided a size and a shape capable of decreasing an unit power consumption, an adsorption column having the optimal shape for the selected adsorbent, and a pressure swing adsorption separation apparatus having an excellent pressure swing adsorption separation performance. In the present invention, an adsorbent having an equivalent diameter within a range of 1.0±0.2 mm or within a range from 12 mesh to 20 mesh is used and the adsorption column is established such that a superficial velocity u [m/s] of a raw material air is set to be within a range of ±25% of u=0.07a +0.095 to the equivalent diameter a [mm].
