METHOD FOR PRODUCING ZEOLITE HAVING CONTROLLED ALUMINUM CONTENT BY ADJUSTING COMPOSITION OF SYNTHESIS MOTHER LIQUOR

摘要

Provided is a method for producing zeolite having a controlled aluminum content, wherein the sodium hydroxide molar concentration of a zeolite synthesis mother liquor can be adjusted to adjust the aluminum content in synthesized CHA. The structure of the low aluminum-content CHA produced by the provided method does not collapse even after a high-temperature hydrothermal treatment, and thus the activity of the CHA as a catalyst can be maintained. Moreover, by adjusting the aluminum content in the structure the properties of the produced CHA significantly change, and thus the CHA can be applied to various fields.
