Method for producing beta zeolite

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.
