Abstract: The present invention relates to a surface modified zeolite adsorbent wherein the surface of said zeolite is modified with a coating comprised of a silicone derived species, said zeolite having a mean crystal size from about 5 to about 10 ?m and a skeletal density of ?1.10 gr./cc. The invention is based on the discovery that larger crystals tend to have higher particle density, and the packing of the larger crystals in agglomeration processes leads to more idealized packing to provide a larger mean-pore diameter. The surface modified adsorbent provides rate selectivity for one gas over others is described. 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.

Abstract: The present invention relates to a superior carbon adsorbent with or without a core. In one embodiment the carbon adsorbent of the present invention employs carbon adsorbent powder and an organic binding agent which are combined together with an appropriate solvent in an agglomeration step. In another embodiment the invention contemplates a core-in-shell adsorbent comprising an outer shell composed of a carbon and a non-adsorbing inert inner core. Low temperature processing of these agglomerates substantially preserves the binding agent within the final composition and allows one to prepare adsorbent products of high sphericity. The adsorbents of the invention possess superior characteristics such as higher mass transfer rate and CO2 working capacity for use in a H2PSA process.

Abstract: An adsorption process for xenon recovery from a cryogenic liquid or gas stream is described wherein a bed of adsorbent is contacted with the aforementioned xenon containing liquid or gas stream and adsorbs the xenon selectively from this fluid stream. The adsorption bed is operated to at least near full breakthrough with xenon to enable a deep rejection of other stream components, prior to regeneration using the temperature swing method. Operating the adsorption bed to near full breakthrough with xenon, prior to regeneration, enables production of a high purity product from the adsorption bed and further enables oxygen to be used safely as a purge gas, even in cases where hydrocarbons are co-present in the feed stream.
