摘要： PROBLEM TO BE SOLVED: To provide a new chabazite type zeolite whose nitrogen oxide cleaning rate at a low temperature is higher even if it is applied with hydrothermal endurance treatment before compared with a chabazite type zeolite catalyst to which only copper is held as a catalyst of reducing and removing a nitrogen oxide.SOLUTION: The chabazite type zeolite is provided to which copper and an alkaline earth metal are held. It is desirable that the alkaline earth metal is at least one selected from a group composed of calcium, magnesium and barium. Furthermore, it is desirable that an SiO/AlOmolar ratio is 10-50, and an atomic ratio of copper/aluminum is 0.15-0.25. After the hydrothermal endurance treatment, the nitrogen oxide cleaning rate of such a chabazite type zeolite is higher than that of the chabazite type zeolite catalyst to which only conventional copper is held.

摘要： PROBLEM TO BE SOLVED: To provide a chabazite-type zeolite having a high Al content as a substrate of a catalyst support or an adsorbent from the standpoint of the number of ion exchange sites or the solid acid amount, and having high durability and heat resistance; a method for producing the same; and a new chabazite-type zeolite having copper supported.SOLUTION: In the chabazite-type zeolite, the mole ratio of SiO/AlOis less than 15 and the average particle diameter is ≥1.0 and ≤8.0 μm. The chabazite-type zeolite has excellent durability and heat resistance. In the chabazite-type zeolite having copper supported, the rate of reduction of the nitrogen oxide at low temperature is improved compared to the conventional chabazite-type zeolite having copper supported.
