Abstract: A CO2 amine scrubbing process uses an absorbent mixture consisting of an alkanolamine CO2 sorbent in combination with a non-nucleophilic base. The alkanolamine has oxygen and nitrogen sites capable of nucleophilic attack at the CO2 carbon atom. The nucleophilic addition is promoted in the presence of the non-nucleophilic, relatively stronger base, acting as a proton acceptor. The non-nucleophilic base promoter, which may also act as a solvent for the alkanolamine, can promote reaction with the CO2 at each of the reactive hydroxyl and nucleophilic amine group(s) of the alkanolamines. In the case of primary amino alkanolamines the CO2 may be taken up by a double carboxylation reaction in which two moles of CO2 are taken up by the reacting primary amine groups.

Abstract: Improved CO2 sorbents comprised of a mesoporous silica functionalized with a polyamine are obtained by the in-situ polymerization of azetidine. Also included herein are processes utilizing the improved CO2 sorbents wherein CO2 is chemisorbed onto the polyamine portion of the sorbent and the process is thermally reversible.

Abstract: There is provided a method for preparing crystalline ultra-large pore oxide materials. The materials are formed from reaction mixtures comprising an amphiphilic compound, such as a cetyltrimethylammonium compound, a source of at least one oxide, such as silica, and water. The concentration of amphiphilic compounds in these reaction mixtures is rather low. The addition of an inorganic salt, such as sodium bromide, to the reaction mixture may result in the increased thermal stability of the as-synthesized form of the crystalline material and may also alter the crystalline phase of the product.

Abstract: There is disclosed a low density polymer having a broad molecular weight distribution, such that its melt flow ratio (MFR) is about 50 to about 250, and a substantially constant melt index-corrected density. The polymer, produced e.g., by blending a first polymer component of high molecular weight with a second polymer component of low molecular weight, with both polymer components having substantially the same melt index-corrected density, produces films having improved strength properties and low hexane extractables, as compared to films made from comparable individual polymer components.There is also disclosed a low density polymer, also having MFR of about 50 to about 250, having substantially no polymer chains having low molecular weight and short chain branches, which is prepared by blending a first polymer component of low density and high molecular weight with a second polymer component of relatively high density and relatively low molecular weight.
