Sorbent material sheets are wound around a center core of material that includes additional sorbent. This configuration further increases the packaging efficiency and performance of the sorbent material sheets as part of an overall housing or apparatus. In some embodiments, the sorbent material sheets are arranged in a stacked configuration. Configurations of the sorbent material sheets as part of a canister are also described.

Coating compositions and methods for using the same are disclosed. The coating compositions can include an aminosilica adsorbent. The coating compositions can adsorb CO.sub.2.

A process of removing methanol, CO.sub.2, or both from a hydrocarbon stream is described. The process uses an adsorbent comprising binderless type 3A zeolite. The adsorbent has high methanol removal capacity and low olefin co-adsorption capacity, as well as low reactivity in an olefin stream. This allows reduced adsorbent loading while maintaining downstream catalyst performance and product quality. The adsorbent comprises a type 3A zeolite comprising less than 5% of a binder and an ion exchange ratio of 30% to 70%. The adsorption process can obtain an outlet methanol content of 1 ppmw or less.

The present disclosure relates to compositions including metal-organic framework materials and a polymeric binder. The compositions may have a crush strength of about 2.5 lb-force or greater. The present disclosure also relates to processes for producing metal-organic framework extrudates. Processes may include mixing a metal-organic framework material, a polymeric binder, and optionally a solvent to form a mixture. The process may also include extruding the mixture to form a metal-organic framework extrudate.

The present invention relates to a method for modifying the crystalline inorganic framework of an adsorbent with coatings to provide rate selectivity for one gas over others is described. The method described herein narrows the effective pore size of crystalline porous solids with pores less than about 5 Å for rate selective separations. This method of the invention comprises treating the hydrated or partially hydrated zeolite with a silicone derived binding agent followed by subsequent heat treatment. The additive content and treatment are adjusted to match effective pore size to specific separations. The superior adsorbent has the added convenience of bead forming simultaneously with pore modification as well as having the treatment result in the yielding of high crush strength products.
