Beta zeolite and method for producing same

Abstract

Provided is a method for producing a beta zeolite, the method including bringing a beta zeolite parent powder synthesized without using an organic structure-directing agent into contact with an alkaline aqueous solution having a pH of 12 or higher. The liquid temperature of the alkaline aqueous solution is preferably se to 40° C. or above and 100° C. or below. The ratio of the parent powder to the alkaline aqueous solution is preferably set to 10 g/L or greater and 1000 g/L or less. The contact time is preferably 0.5 hours or longer and 48 hours or shorter. The SiO2/Al2O3 molar ratio is preferably s16 or less.
