An absorbent article comprising an absorbent gelling material (AGM) having an encapsulated compound of one or more odor controlling organic compounds disposed upon a surface thereof is described. Alternatively, an AGM particle comprising an encapsulated reactive compound of one or more odor controlling organic compounds disposed as a surface coating thereon is described. Additionally, a method to manufacture an absorbent article is described. The method provides for the steps of: a) providing a solution in a solvent system, the solution has an encapsulating agent and one or more odor controlling organic compounds as a surface coating; b) applying an amount of the solution to a surface of an AGM particle; and, c) incorporating the AGM particle having the solution applied thereto into the absorbent article.

An adsorbent having a microwave absorption property is provided. The adsorbent having an improved microwave absorption property, which has a core-shell structure including a silicon carbide bead disposed therein, and an adsorbing material disposed outside the silicon carbide bead, can be provided. Also, the adsorbent may further include a plurality of silicon carbide particles dispersed and disposed therein and having a diameter of 1 μm to 10 μm, and the adsorbing material may be ion-exchanged with a cation. Therefore, the adsorbent can be useful in improving desorption efficiency since the adsorbent may be rapidly heated by microwaves to reach the desorption temperature due to high reactivity to microwaves. Also, the adsorbent can be useful in maintaining full adsorption capacity without having an influence on adsorption quantity since the silicon carbide bead is disposed in the inner core of the adsorbent. Further, when the adsorbent is applied to conventional systems for removing organic compounds using microwaves or dehumidification systems, the adsorbent can be semi-permanently used, and may also have an effect of enhancing the energy efficiency by 30% or more, compared to adsorbents used in the conventional systems.

Structured adsorbent beds comprising a high cell density substrate, such as greater than about 1040 cpsi, and a coating comprising adsorbent particles, such as DDR and a binder, such as SiO.sub.2 are provided herein. Methods of preparing the structured adsorbent bed and gas separation processes using the structured adsorbent bed are also provided herein.
