Abstract: Provided are a high-performance Cu—P co-supported zeolite and the like having excellent thermal endurance and catalyst performance. A Cu—P co-supported zeolite comprising at least a small pore size zeolite, and an extra-backbone copper atom and an extra-backbone phosphorus atom supported on the small pore size zeolite, wherein a silica-alumina ratio (SiO2/Al2O3) is 7 or more and 20 or less, a ratio of the copper atom to a T atom (Cu/T) is 0.005 or more and 0.060 or less, a ratio of the phosphorus atom to the T atom (P/T) is 0.005 or more and 0.060 or less, and a ratio of the phosphorus atom to the copper atom (P/Cu) is 0.1 or more and 3 or less.

Abstract: A small-pore zeolite that is modified with phosphorus, is excellent in hydrothermal durability, and has an 8-membered oxygen ring structure. The 8-membered oxygen ring structure is CHA, AEI, and AFX. The small-pore zeolite incudes at least an aluminum element, a silica element, a phosphorus element, wherein the phosphorus element is defined by expression (1), and the small-pore zeolite has an 8-membered oxygen ring structure being of CHA, AEI, or AFX. The phosphorus element that modifies the zeolite is unevenly distributed and richly contained on the surface layer side of the zeolite. A method for producing a phosphorus element-containing zeolite.

Abstract: The present invention provides, for example, a compound represented by formula (1), or a salt thereof: wherein R1 to R4 are each independently an alkyl group.

Abstract: A slurry composition for a catalyst and a method for producing the same, a catalyst and a method for producing the same using the slurry composition for a catalyst. The method omits many heretofore required treatment steps and reduces catalyst production cost. The method comprising the steps of providing a slurry composition for a catalyst, comprising at least an aluminosilicate, Cu, and water, and having a solid concentration of 0.1% by mass to 90% by mass, wherein a component for a catalyst has composition represented by Al2O3·xSiO2·yT2O·zCuO (wherein T is a quaternary ammonium cation, and x, y and z are numbers that satisfy 10?x?40, 0.1?y<2.0, and 0.1?z<2.0, respectively) in terms of molar ratio based on an oxide; coating at least one side of a support with this slurry composition; and heat-treating at 350° C. or higher.
