Abstract: A novel synthetic crystalline aluminogermanosilicate molecular sieve material, designated SSZ-117x, is provided which exhibits increased acidity. The SSZ-117x can be synthesized using N,N,N,3,5-pentamethyladamantan-1-ammonium cations as a structure directing agent. The synthesis employs a boron pathway to achieve increased acid sites. The SSZ-117x of increased acidity may be used in organic compound conversion reactions and/or sorptive processes.

Abstract: The method for manufacturing a modified aluminosilicate includes a first step of treating an aluminosilicate with an acid, a second step of primarily calcining the treated material obtained in the first step at 550° C. to 850° C., and a third step of contacting the calcined material obtained in the second step with a liquid containing one or more Group 4 elements and/or Group 5 elements, and then drying and secondarily calcining the resultant. The modified aluminosilicate includes one or more Group 4 elements and/or Group 5 elements, and exhibits an absorbance at 300 nm in an ultraviolet visible spectrum of 1.0 or higher. The method for manufacturing aromatic dihydroxy compounds includes reacting a phenol with hydrogen peroxide in the presence of a specific modified aluminosilicate.

Abstract: Molecular sieves comprising intergrowths of cha and aft having an “sfw-GME tail”, at least one structure directing agent (SDA) within the framework of the molecular sieve, an intergrowth of CHA and GME framework structures, cha cavities, and aft cavities are described. A first SDA comprising either an N,N-dimethyl-3,5-dimethylpiperidinium cation or a N,N-diethyl-2,6-dimethylpiperidinium cation is required. A second SDA, which can further be present, is a CHA or an SFW generating cation. The amount of the second SDA-2 used can change the proportion of the components in the cha-aft-“sfw-GME tail”. Activated molecular sieves formed from SDA containing molecular sieves are also described. Compositions for preparing these molecular sieves are described. Methods of preparing a SDA containing JMZ-11, an activated JMZ-11, and metal containing activated JMZ-11 are described. Methods of using activated JMZ-11 and metal containing activated JMZ-11 in a variety of processes, such as treating exhaust gases and converting methanol to olefins are described.

Abstract: It is intended to provide a novel zeolite with a rare earth element-substituted framework which has a higher amount of NOx adsorbed and a method for producing the same, and a NOx adsorption member and a catalyst for automobile exhaust gas, etc. comprising the same. The present invention provides a zeolite with a rare earth element-substituted framework, comprising at least a zeolite and at least one rare earth element selected from the group consisting of Ce, La, Nd and Pr, wherein a content ratio of the rare earth element is 1 to 15% by mass in total based on the total amount, and one or some of Al and/or Si atoms constituting the framework of the zeolite are replaced with the rare earth element.

Abstract: Gallium-68 generators that are capable of producing gallium-68 from a germanium-68 source material are disclosed. The source material may be a matrix material (e.g., zeolite) in which germanium-68 is isomorphously substituted for central atoms in tetrahedra within the matrix material. Methods for forming gallium-68 generators are also disclosed.
