METHOD OF MANUFACTURING FINE ZEOLITE

METHOD OF MANUFACTURING FINE ZEOLITE

PROBLEM TO BE SOLVED: To provide a method of manufacturing fine zeolite with no amorphous substance or a very little amount of amorphous substance because when fine zeolite crystal with a particle size of ≤0.5 μm or less is manufactured by crushing zeolite, the zeolite is made amorphous, crystallini...

description PROBLEM TO BE SOLVED: To provide a method of manufacturing fine zeolite with no amorphous substance or a very little amount of amorphous substance because when fine zeolite crystal with a particle size of ≤0.5 μm or less is manufactured by crushing zeolite, the zeolite is made amorphous, crystallinity is degraded, and original performance of the zeolite can not be achieved.SOLUTION: The fine zeolite with the particle size of ≤0.5 μm obtained by crushing zeolite once is dispersed in a silicate solution having a specific composition, and is recrystallized to manufacture the fine zeolite with no amorphous substance or a very little amount of amorphous substance. The obtained zeolite fine particle exhibits improved crystallinity, and achieves excellent performance such as catalyst characteristics.
