Abstract: The present disclosure relates to a method of separating a compound of interest, particularly unsaturated compound(s) of interest, from a mixture. The compound is separated using a column having a chromatographic stationary phase material for various different modes of chromatography containing a first substituent and a second substituent. The first substituent minimizes compound retention variation over time under chromatographic conditions. The second substituent chromatographically and selectively retains the compound by incorporating one or more aromatic, polyaromatic, heterocyclic aromatic, or polyheterocyclic aromatic hydrocarbon groups, each group being optionally substituted with an aliphatic group. In some examples, the present disclosure can include a chromatographic system having a chromatographic column having a stationary phase with a chromatographic substrate containing silica, metal oxide, an inorganic-organic hybrid material, a group of block copolymers, or a combination thereof.

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 μm 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 provides an acidic gas adsorbent having improved heat resistance. The acidic gas adsorbent of the present invention includes a porous body, and an amine compound being a solid and being supported on surfaces of pores of the porous body. The acidic gas adsorbent includes, for example, a cover layer covering the surfaces of the pores of the porous body, and the cover layer includes the amine compound. As an example, when each pore of the porous body is assumed to have a spherical shape, the cover layer has a thickness of 5.0 nm or less, the thickness being calculated from the average pore diameter of the porous body, the pore volume of the porous body, and the pore volume of the acidic gas adsorbent.
