Title:

BETA-TYPE ZEOLITE AND PRODUCTION METHOD THEREOF

Document Type and Number:

Japanese Patent JP2015218084

Kind Code:

A

Abstract:

PROBLEM TO BE SOLVED: To provide a beta-type zeolite that contains zinc and that has a small particle size.SOLUTION: The beta-type zeolite of the present invention contains silicon oxide and zinc oxide. The average particle size at cumulative frequency 50% in particle size distribution measured by scanning electron microscope observation is 50 nm or more and 100 nm or less. The SiO/AO(A represents at least one trivalent element selected from the group consisting of aluminum, iron, boron and gallium) mole ratio is preferably 100 or more and 250 or less. The SiO/ZnO mole ratio also is preferably 15 or more and 80 or less.
