How to understand the relationship between adsorption time and the number of times the adsorbent is regenerated
Thread Content
Generally, increasing the hydrogen recovery rate involves extending the adsorption time within a certain range. The longer the adsorption time, the fewer times the adsorbent needs to be regenerated, which reduces the amount of water required for washing; thus, the recovery rate can be improved. But from my understanding, shouldn’t a longer adsorption time result in more regeneration cycles? I hope the seniors can help me figure out why the longer the adsorption time, the fewer times the adsorbent needs to be regenerated
To give a simple example, suppose the adsorption time is 120 seconds; then 30 adsorptions can be carried out within one hour, meaning the adsorbent is regenerated 30 times. If the adsorption time is extended to 240 S, with only 15 adsorptions per hour, the number of times the adsorbent needs to be regenerated is 15. So this reduces the number of times the adsorbent needs to be regenerated; I’m not sure if this understanding is correct.
