Abstract
The catalyst is an L-type zeolite with platinum supported thereon, which is then treated with a halogen-containing compound. The catalyst has a long catalyst life and is extremely useful for the preparation of aromatic hydrocarbons from aliphatic hydrocarbons. The process using the catalyst provides a production of aromatic hydrocarbons with a high yield.
