摘要： PROBLEM TO BE SOLVED: To provide a radial type adsorption container capable of improving separation performance, reducing power consumption and achieving easy production and maintenance by suppressing gas drift and reducing pressure loss by a simple structure.SOLUTION: A radial type adsorption container includes a material gas passage 2 annularly arranged on an inner peripheral part of a cylindrical container 1, a product gas passage 3 arranged on a center part of the cylindrical container 1 and an adsorbent layer 4 formed between the material gas passage 2 and the product gas passage 3. An inlet 5 for introducing material gas into the cylindrical container 1 is connected to the material gas passage 2 on the one-end side of the cylindrical container 1 in an axial direction, an exhaust port 6 for exhausting product gas from the cylindrical container 1 is connected to the product gas passage 3 on the one-end side of the cylindrical container 1, and the ratio of the passage cross section of the material gas passage 2 to the passage cross section of the product gas passage 3 is set to 1.2 to 3.3. Consequently drift can be effectively suppressed without using a complicated structure such as a taper-shaped or conical structure, and the uniformity of gas flow can be enhanced.
