    摘要： Provided is a method for producing a beta zeolite, which is a seed crystal addition method that is capable of reducing the environmental load as much as possible. A method for producing a beta zeolite according to the present invention comprises a step wherein a reaction mixture that contains a silica source, an alumina source, an alkali source and water and a seed crystal that is composed of a beta zeolite are mixed with each other and heated. A beta zeolite which comprises particles having a particle size of 10 µm or less in an amount of 90% or more on a volume basis in the particle size distribution as determined by a laser diffraction/scattering particle size distribution measuring method, and which is synthesized without using an organic structure-directing agent is used as the seed crystal.

    摘要： Provided is a method that is for producing a PAU zeolite and that can have an environmental impact that is reduced while, as much as possible, not using a structure-defining agent. The method for producing a PAU zeolite produces by means of (1) mixing a silica source, an alumina source, an alkali source, and water in a manner so as to result in a reaction mixture having a composition represented by a specific mole ratio, (2) using as the seed crystal a PAU zeolite that does not contain organic compounds and has a SiO 2 /Al 2 O 3 ratio of 4-15 and an average particle size of at least 100 nm, and adding same to the reaction mixture at a ratio of 0.1-20 wt% with respect to the silica component in the reaction mixture, and (3) subjecting the reaction mixture to which the seed crystal has been added to sealed-vessel heating at 80-200 °C.

    摘要： A process for producing a VET-type zeolite is provided in which the use of a structure-directing agent is minimized and the environmental burden can be minimized. This process for producing a VET-type zeolite comprises (1) mixing a zinc source, an element M 1 source, an alkali source, and water so as to result in a reaction mixture having a specific composition in terms of molar ratio, (2) using, as seed crystals, a VET-type zeolite which has an M 1 O 2 /ZnO ratio of 5-30 and adding the zeolite to the reaction mixture in an amount of 0.1-30 wt% relative to the M 1 O 2 contained in the reaction mixture, and (3) heating the reaction mixture to which the seed crystals have been added, at 80-200°C in a hermetically closed state. M 1 represents silicon or a mixture of silicon and germanium.
