ABSTRACT:
A process for producing aromatic hydrocarbons comprising contacting at least one hydrocarbon of the paraffin series, olefin series, acetylene series, cyclic paraffin series or cyclic olefin series with a catalyst containing an L-type zeolite containing both platinum components and halogen components supported thereon, the catalyst having a peak intensity of 0.4 or less as determined by X-ray absorption near edge structure (XANES), and the amount of dealuminization in the zeolite is 3% by weight or less, based on the total amount of aluminum therein.
