Abstract: This disclosure provides polyamine sorbent compositions for the separation of metals from aqueous solutions. The polyamine sorbent compositions comprise a silica support, an aminosilane bound to the silica support, an epoxysilane bound to the silica support, and a polyamine where the polyamine is chemically tethered onto a solid silica support through via the epoxysilane. The polyamine may be further stabilized within the bulk sorbent through hydrogen bonding interactions with the aminosilane. The sorbent compositions resist leaching by H2O in an aqueous stream containing heavy oxyanion-based (and other) metals and demonstrate stability over a pH range of 2-14. The sorbent compositions are useful for the separation of metals from aqueous solutions. The cationic heavy metals are captured by the co-existing amine groups (—NH2, —NH, —N) from the polymeric network while additional metal capture capacity is derived from the introduction of a secondary silane linker.

Abstract: A heat transfer fluid can be used as part of a multi-phase adsorption environment to allow for improved separations of gas components using a solid adsorbent. The heat transfer fluid can reduce or minimize the temperature increase of the solid adsorbent that occurs during an adsorption cycle. Reducing or minimizing such a temperature increase can enhance the working capacity for an adsorbent and/or enable the use of adsorbents that are not practical for commercial scale adsorption using conventional adsorption methods. The multi-phase adsorption environment can correspond to a trickle bed environment, a slurry environment, or another convenient environment where at least a partial liquid phase of a heat transfer fluid is present during gas adsorption by a solid adsorbent.

Abstract: A manganese dioxide nanowire @ multidimensional mesoporous metal-organic framework adsorbent and application method thereof for removing heavy metals from water. A multidimensional mesoporous metal-organic framework material is prepared from metal ions and organic ligands by means of a self-assembly reaction; a manganese dioxide nanowire is prepared from manganese salt and thiosulfate by means of reaction in a reaction kettle. The adsorbent possesses not only the characteristics of a multidimensional mesoporous metal-organic framework material, such as reticulated pore adaptation, a large specific surface area, and abundant reaction sites, but also the oxidative and catalytic properties of manganese dioxide nanowire.

Abstract: The present invention relates to a method for manufacturing a carbon dioxide absorbent and to the absorbent manufactured by the method. The method comprises: (A) a step of preparing a slurry composition including a carrier composition containing a support, an inorganic binder, and a solvent; (B) a step of preparing solid particles by spray drying the thus-prepared slurry composition; (C) a step of manufacturing a carrier by dry calcining the thus-prepared solid particles; and (D) a step of receiving an amine compound into the pores of the thus-manufactured carrier. According to the absorbent of the present invention, an absorbing reaction and a regenerating reaction at a low temperature range (less than or equal to 100° C. may be conducted, and therefore, the cost for capturing CO2 in a dry capturing process may be expected to decrease.
