Abstract

Provided are: novel zeolite having an extremely small amount of specific Bronsted acid sites on the surface thereof, which is expected to be useful as a catalyst for the aromatization of a non-aromatic hydrocarbon typified by an aliphatic hydrocarbon; and a catalyst for use in the production of an aromatic hydrocarbon, which comprises the zeolite. Zeolite characterized by satisfying the following requirements (i) to (iii). (i) The zeolite has an average particle diameter of 100 nm or less. (ii) The zeolite is 10-membered ring microporous zeolite. (iii) The amount of the Bronsted acid sites on the outer surface of the zeolite is 0.1 to 10.0 μmol/g.
