  • Patent number: 11065606
    Abstract: The purpose of the present invention is to provide a metal-substituted beta zeolite that exhibits a more excellent catalytic performance than conventional one, and a method for producing the same. The present invention provides a metal-substituted beta zeolite by subjecting an alkali metal-form beta zeolite produced without using an organic structure-directing agent to ion exchange with ammonium ion and then, using a filter cake procedure, to ion exchange with copper ion or iron(II) ion. The present invention also provides a metal-substituted beta zeolite which has been ion exchanged with copper ion or iron(II) ion and in which the amount of Lewis acid sites is greater than the amount of Bronsted acid sites when the amount of Bronsted acid sites and the amount of Lewis acid sites are measured by ammonia infrared-mass spectroscopy temperature-programmed desorption on the as-produced state.
