    摘要: 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 then 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.

    摘要: The aromatic hydrocarbons rich in benzene, toluene and xylene are prepared from a hydrocarbon feed having from 6 to 12 carbon atoms by feeding the hydrogen in admixture with hydrogen in a ratio ranging from 0 to less than 1 mole with respect to each mole of the hydrocarbon, into contact with a catalyst prepared by depositing at least one metal belonging to group VIII of the periodic table on a macroporous zeolite treated with a halogenated compound. The aromatic hydrocarbons rich in benzene, toluene and xylene are useful as a base for high octane number gasoline or as petrochemical raw materials.
