Abstract

[Problem] The purpose of the present invention is to provide: a pentasil-type zeolite that combines a higher BET specific surface area and a higher acid amount than previously; and a method for manufacturing said pentasil-type zeolite. [Solution] A pentasil-type zeolite characterized in that the BET specific surface area thereof is 450 m/g or more, and furthermore the acid amount thereof, measured by the ammonia-TPD method, is 0.38 mmol/g or more. This pentasil-type zeolite can be obtained by a manufacturing method which has a crystallization step for crystallizing a mixture containing tetrabutylphosphonium cations, a silica source, an alumina source, an alkali metal source, and water, and which is characterized in that the molar ratio of the alkali metal relative to the silica in the mixture is greater than 0.04 and less than 0.10.
