Description

Technical Field

[0001] This application relates to a device for testing the performance of adsorbents, which belongs to the field of pressure swing adsorption. Background Technology

[0002] In the field of adsorbent performance testing, adsorbents, as important adsorbent materials, are widely used in gas adsorption, water treatment, and soil remediation. To effectively evaluate adsorbent performance, testing equipment is an indispensable key technical support tool. However, existing technologies still have certain limitations. First, traditional adsorbent performance testing devices mainly rely on single or limited test indicators, such as adsorption capacity, selectivity, regeneration capacity, and temperature stability. While these indicators can partially reflect the performance of the adsorbent, they cannot comprehensively and dynamically evaluate its overall performance. Furthermore, traditional devices are typically complex to operate, bulky, wasteful of consumables, and have low testing efficiency, making it difficult to meet the demands of modern environmental protection and industrial applications for efficient and accurate testing.
