MANUFACTURING METHOD OF MSE TYPE ZEOLITE

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method of MSE type zeolite capable of manufacturing the MSE type zeolite with a relatively short heating time by using inexpensive tetraethylammonium ion.SOLUTION: There is provided a manufacturing method of MSE type zeolite including (1) mixing a silica source, an alumina source, an alkali source, tetraethylammonium ion and water to prepare a reaction mixture with a composition represented by a molar ratio described as SiO/AlO=10-100, (NaO+KO)/SiO=0.15-0.50, KO/(NaO+KO)=0.05-0.7, TEAO/SiO=0.08-0.20, HO/SiO=5-50, (2) adding MSE type zeolite seed crystal to the mixture at a ratio of 5-30 mass% based on the silica component and (3) heating the reaction mixture to which the seed crystal is added at a temperature of 100-200°C under a sealed condition.SELECTED DRAWING: Figure 8
