Abstract

There are disclosed a new L-type zeolite and a catalyst comprising said zeolite, having a high and persistent catalytic activity for a long-term production of aromatic hydrocarbon and a process for efficiently producing aromatic hydrocarbons from nonaromatic hydrocarbon by the use of the catalyst. The L-type zeolite with both platinum components and halogen components supported thereon, has a peals intensity of 0.4 or less as determined by XANES and a small amount of dealuminization.
