COLLOIDAL SOLUTION FOR PRODUCING amp;beta;-ZEOLITE AND METHOD FOR PRODUCING amp;beta;-ZEOLITE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a colloidal solution capable of crystallizing β-zeolite in a short of time, and a method for synthesizing β-zeolite using the same.;SOLUTION: The colloidal solution containing Si and Al contains particles having a modal particle diameter of 0.01-0.2 μm, wherein the proportion of particles having ≥0.5 μm is ≤3%. The molar ratio of OH/Si is preferably 0.20 to 0.80. When such the colloidal solution is added to a reaction liquid containing Si, Al and tetraethylammonium for crystallization, β-zeolite can be crystallized in a short period of time.;COPYRIGHT: (C)2012,JPO&INPIT
