Title:
ＭＳＥ型ゼオライトの製造方法
Document Type and Number:
Japanese Patent JP6734692
Kind Code:
B2
Abstract:
The objective of the invention is to provide an MSE-type zeolite production method such that an MSE-type zeolite can be produced in a comparatively short heating time by using inexpensive tetraethylammonium ion. The production method of the present invention comprises steps of:
(1) mixing a silica source, an alumina source, an alkali source, tetraethylammonium ion, and water in such a manner as to yield a reaction mixture of the composition represented by the molar ratios indicated below:
SiO 2 /Al 2 O 3 = between 10 and 100 inclusive
(Na 2 O + K 2 O)/SiO 2 = between 0.15 and 0.50 inclusive
K 2 O/(Na 2 O + K 2 O) = between 0.05 and 0.7 inclusive
TEA 2 O/SiO 2 = between 0.08 and 0.20 inclusive
H 2 O/SiO 2 = between 5 and 50 inclusive;
(2) using the MSE-type zeolite as a seed crystal, and adding this seed crystal to the mixture at a proportion of 5 to 30% by mass with respect to the silica component in the reaction mixture; and
(3) heating, under hermetic seal at a temperature of 100 to 200°C, the reaction mixture whereto the seed crystal has been added.
