Abstract: Provided here are adsorbent compositions containing polyvinyl alcohol-bonded pellets of zeolite templated carbon. Also provided here are methods of producing adsorbent compositions by forming an aqueous mixture containing a binder, water, and zeolite-templated carbon; subjecting the aqueous mixture to a drying process to remove the water and form a dry mixture of the binder and the zeolite-templated carbon, and compacting the dry mixture of the binder and the zeolite-templated carbon to form the binder-bonded pellets of the zeolite templated carbon.

Abstract: A core-shell type amine-based carbon dioxide adsorbent is described, including a chelating agent resistant to oxygen and sulfur dioxide, to inhibit oxidative decomposition of amine. As a core, a porous support is employed on which an amine compound is immobilized, and, as a shell, an amine layer resistant to inactivity by sulfur dioxide is utilized. Such adsorbent exhibits high oxidation resistance because the chelating agent functions to remove a variety of transition metal impurities catalytically acting on amine oxidation. In addition, the sulfur dioxide-resistant amine layer of the shell selectively adsorbs sulfur dioxide to protect the amine compound of the core and, at the same time, the amine compound of the core selectively adsorbs only carbon dioxide. Sulfur dioxide adsorbed on the shell is readily desorbable therefrom at about 110° C. and thus remarkably improved regeneration stability is obtained during temperature-swing adsorption (TSA) processes in which sulfur dioxide is present.

Abstract: Embodiments provide a methane microporous carbon adsorbent including a thermally-treated CVD carbon having a shape in the form of a negative replica of a crystalline zeolite has a BET specific surface area, a micropore volume, a micropore to mesopore volume ratio, a stored methane value and a methane delivered value and a sequential carbon synthesis method for forming the methane microporous carbon adsorbent. Introducing an organic precursor gas for a chemical vapor deposition (CVD) period to a crystalline zeolite that is maintained at a CVD temperature forms the carbon-zeolite composite. Introducing a non-reactive gas for a thermal treatment period to the carbon-zeolite composite maintained at a thermal treatment temperature forms the thermally-treated carbon-zeolite composite. Introducing an aqueous strong mineral acid mixture to the thermally-treated carbon-zeolite composite forms the methane microporous carbon adsorbent. The crystalline zeolite includes tri-ethanolamine (TEA) and has a shape that is orthogonal with a mid-edge length in a range of 8 μm to 20 μm.

Abstract: A method for the large-scale synthesis of a zeolite-templated carbon (ZTC). The method includes the steps of: introducing a bed material comprising a zeolite to a fluidized bed reactor and heating the bed material to a temperature between 550° C. and 800° C.; fluidizing the bed material with a fluidizing gas and maintaining the temperature of the bed material between 550° C. and 800° C.; introducing an organic carbon precursor while fluidizing the zeolite for a period of time such that carbon is deposited on the zeolite by chemical vapor deposition to produce a zeolite-carbon composite; and treating the zeolite-carbon composite with an acid solution such that the zeolite template is dissolved and the ZTC is obtained.

Abstract: Provided are a method of removing a perchlorate ion (ClO4−) and a nitrate ion (NO3−) which are toxic anions in wastewater using an anion-exchange resin on which a metal is supported, and more particularly an anion-exchange resin on which a hydrogen activating metal is supported or a hydrogen activating metal and a secondary metal are supported together and a method of removing toxic anions using the same. The toxic anions may be efficiently ion-exchanged and removed using an anion-exchange resin supporting a reduction catalyst, the regeneration of the anion-exchange resin may be facilitated, and the consumption of energy and the reducing agent may be reduced, thereby being usable in removal of toxic anions from an actual water purification system.
