  • Method and kit for adsorbent performance evaluation
    Patent number: 7827855
    Abstract: The present invention generally relates to methods and kits for measuring and analyzing degradation of adsorbent materials, particularly for adsorbent materials used in gas separation processes. The present invention can assess the damage to adsorbent due to contamination including moisture contamination and it can assess damage that is not contaminant-related. The advantage to the present invention is that it can detect degradation of adsorbent directly at the plant site before the degradation affects production. Another advantage is that it can conclusively determine whether the adsorbent is damaged. Because it is so inexpensive to run, the test of the present invention can be conducted to determine adsorbent damage and to confirm whether the damage continues to be an issue. The present invention can test adsorbents in any form, including, but not limited to, bead, pellet or powder form.
    Type: Grant
