LOWER-HYDROCARBON AROMATIZATION CATALYST AND METHOD FOR PRODUCING LOWER-HYDROCARBON AROMATIZATION CATALYST

摘要

The present invention contributes to enhancing the catalytic activity of a lower-hydrocarbon aromatization catalyst for generating an aromatic compound by catalytic reaction of a lower hydrocarbon, and to enhancing the formability of the catalyst. The lower-hydrocarbon aromatization catalyst of the present invention is obtained by compression molding a mixture obtained by mixing a metallosilicate having a large particle diameter on which a catalytic metal is supported, and a metallosilicate having a small particle diameter on which a catalytic metal is supported. A metallosilicate having a particle diameter of 1.0 µm to 5.0 µm is used as the metallosilicate having a large particle diameter, and a metallosilicate having a particle diameter of 0.1 µm to 1.0 µm is used as the metallosilicate having a small particle diameter. The ratio of the metallosilicate having a large particle diameter with respect to the mass of the lower-hydrocarbon aromatization catalyst is 20% to 80%.
