ADSORBENT FOR RAPID PRESSURE SWING ADSORPTION PROCESS

摘要

IMPROVED ADSORBENT FOR RAPID PRESSURE SWING ADSORPTION PROCESS The performance of rapid pressure swing adsorption processes is enhanced by the use of selective adsorbent material in the novel form of millibeads of essentially smooth, rounded particles having a particle size of about -40+80 mesh. U.S. Standard Sieve Series. The millibeads are preferably molecular sieve materials, such as zeolites A, X, and Y, that, in some embodiments, is mixed with a suitable binding agent. Such adsorbent material can be advantageously packed in the adsorbent bed, with minimized settling and crushing in use, so that compacted plug formation is avoided and gas flow to and from the bed, and process performance are enhanced over the course of continuous cyclic processing operations.
