Abstract
The ability of a packed bed of adsorbent to hold a gas is increased by employing at least two sizes of adsorbent particles having nominal diameters differing by at least 7/1. In a preferred embodiment, the capacity of a bed of carbon molecular sieve particles for adsorption of natural gas is significantly improved.

A method of increasing the packing density of particulate adsorbents in a bed of such particles comprising combining two uniform size particles having nominal diameters differing by a ratio of about 7/1, the larger particle being a pellet having a diameter/height ratio of about 1/1 and the smaller particle being a sphere.
A packed bed of adsorbent particles consisting essentially of two particle sizes having nominal diameters differing by a ratio of about 7/1, the larger particle being a pellet having a diameter/height ratio of about 1/1, and the smaller particle being a sphere.
