<p>PROBLEM TO BE SOLVED: To provide an adsorption column which can restrain the temperature decrease of the lower part of the column and prevent the deterioration of the capacity of an adsorbent without making gas intervene and without using a heat source such as electricity. SOLUTION: A cylindrical adsorption column inner wall 6 is installed in an adsorption column composed of an adsorption column outer wall 2, an upper part mirror plate 3, and a lower part mirror plate, adsorbent supporting structures 5a, 5b having numbers of vent holes in the lower parts of the inner and outer parts of the wall 6 are installed, a gas passage 7 is formed between the upper end of the wall 6 and the mirror plate 3, and a gas inlet 8 to the outside of the wall 6 and a gas outlet 9 from the inside of the wall 6 are formed in the mirror plate 4.</p> |
