What is Zeolite Monoliths for Air Separation about?
xperiments have been carried out on two individual idealized steps in a pressure swing cycle in order to compare the performance of a novel adsorbent monolith with that of a packed bed of commercial pellets containing the same weight of adsorbent. The application is the production of oxygen-enriched air using 5A zeolite. For feed pressures up to 3.8 bar, maximum oxygen compositions in the constant pressure production step up to 100% and 52% were achieved for the monolith with the previous step being carried out (1) by purging the column with pure oxygen at 1 bar, and (2) by evacuating the column, respectively. For virtually all experimental conditions studied, the separative performance of the monolith was found to be somewhat inferior to that of the bed of pellets, this being due largely to the former' s poorer ® lm mass transfer coef® cient together with the virtual independence of this coef® cient on velocity. To its advantage, however, the pressure drop through the monolith was found to be 3-5 times lower than that through the equivalent packed bed and consequently the time to pressurize the monolith was found to be 3-5 times faster than for the bed of pellets. This experimenta
