摘要

The interparticle voids in a PSA adsorbent bed is filled with fine particles. The ratio of the smallest dimension of the coarse adsorbent particles to the largest dimension of the fine particles is in the range 5:1 to 15:1. The fine particles themselves are preferably between about 40 and 60 US mesh in size. The fine particles in the bed occupy from 10 to 50% by volume of the bed. The fine particles may be of comminuted adsorbent or of an inert material, ie one having no adsorptive capacity.
