Abstract
Abstract A catalyst for production of aromatic hydrocarbons and a process for producing aromatic hydrocarbons from various hydrocarbons using said catalyst are disclosed. The catalyst comprises a L-type zeolite treated with a halogen-containing compound and platinum deposited thereon, which is of high activity and has a long service life. The process of the present invention using the catalyst enables to produce aromatic hydrocarbons in a yield as high as not less than 80% for a long time. The hydrocarbon feedstock is selected from paraffin, olefin, acetylene, cyclic paraffin, and cyclic olefin-based hydrocarbons.
