    Abstract: Provided is a method for producing a MAZ-type zeolite, the method having an environmental impact which has been reduced as much as possible while not using a structure-directing agent as far as possible. In the method for producing a MAZ-type zeolite according to the present invention: (1) a silica source, an alumina source, an alkali source and water are mixed so as to form a reaction mixture that has a composition represented by a specific molar ratio; (2) a MAZ-type zeolite, which has a SiO2/Al2O3 ratio of 5-10, has an average particle diameter of at least 0.1 μm and does not contain an organic compound, is added, as a seed crystal, into the reaction mixture in an amount of 0.1-30 weight % relative to the silica components in the reaction mixture; and (3) the reaction mixture, into which the seed crystal has been added, is heated at 80-200° C. in a closed system.

    Abstract: 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.
