Abstract:
1. A method of determining gas capacity of an adsorbent material used in a gas separation or purification process comprising the steps of: (a) taking a sample of the adsorbent material used in the gas separation process and placing the sample in a container means in a controlled environment purged with a dry test gas; (b) adsorbing the test gas onto the sample of adsorbent material; (c) measuring out a fixed volume of or weighing the sample of the adsorbent material in the controlled environment; (d) saturating the sample with a liquid displacing agent and displacing the adsorbed test gas from the sample of adsorbent material; (e) measuring the volume of test gas released from the sample of adsorbent material; and (f) determining the gas capacity by calculating the ratio of test gas released to the weight or volume of the sample.
