MANUFACTURING METHOD OF ZEOLITE FINE PARTICLE POWDER, AND ZEOLITE FINE PARTICLE POWDER

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method of fine particle zeolite maintaining crystallinity which has a small particle size, and is easily re-dispersible into a liquid medium, and fine particle zeolite.;SOLUTION: There are provided a manufacturing method of zeolite fine particle powder having the following processes (1) and (2), and zeolite fine particle powder having a volume average particle diameter d₉₀ of 1.5 μm or less in which content of organic substance is 0.1 mass% or less. Process (1): a process of wet-pulverizing zeolite in a liquid medium to obtain zeolite slurry (2): a process of drying zeolite slurry obtained in process (1) by a spray-dry method to obtain zeolite fine particle powder.;COPYRIGHT: (C)2015,JPO&INPIT
