A carbon adsorbent storage and dispensing system is provided with a structurally modified particulate carbon adsorbent designed with optimal volumetric surface area for a certain range of particle sizes. Bulk density and specific surface area are carefully balanced to ensure the volumetric surface area remains within an optimal range to create high performance, as measured by dispensing capacity of the dopant fluid that is reversibly adsorbed onto the structurally modified particulate carbon adsorbent.

The present description provides low DBL bleed emission performance properties that allows the design of evaporative fuel emission control systems that are simpler and more compact than those possible by prior art by inclusion of a vent-side volume comprising a parallel passage adsorbent such as a carbon honeycomb with narrow channel width and low cell pitch.

Methods of preparing the structured adsorbent bed and gas separation processes using the structured adsorbent bed are also provided herein.

A cylindrical column-shaped honeycomb adsorbent has a plurality of cell passages extending along an axial direction of the honeycomb adsorbent. The plurality of cell passages are configured so that a pitch of adjacent cell passages is within a range of 1.5 mm˜1.8 mm, and so that a thickness of a wall between the cell passages is within a range of 0.45 mm˜0.60 mm. With this configuration, the honeycomb adsorbent exhibits BWC (Butane Working Capacity) of 6.5 g/dL or greater. By mixing fibrous meltable core melting away during baking, the honeycomb adsorbent has macropores configured to have a volume of 0.15 mL/g˜0.35 mL/g with respect to an overall weight of the honeycomb adsorbent and metal oxide particles having a proportion of weight of 150˜250% with respect to the activated carbon.
