A process for the dehydrocyclodimerization of C/sub 2/-C/sub 6/ aliphatic hydrocarbons is described comprising passing a feed stream comprising a C/sub 2/-C/sub 6/ aliphatic hydrocarbon component into a reaction zone and contacting the C/sub 2/-C/sub 6/ aliphatic hydrocarbon comprising feed stream with two discrete catalysts wherein the first discrete catalyst comprises a ZSM-5 zeolite component, a phosphorus-containing alumina component, and a metal component selected from the elements of Groups IIB-IVB of the Periodic Table of the Elements and wherein the second discrete catalyst, which is free of the ZSM-5 zeolite component, comprises a catalytic component of lesser acidity than the ZSM-5 zeolite component of the first discrete catalyst. The catalytic component is selected from the group consisting of crystalline aluminosilicates, metal oxides, amorphous silicaalumina, and crystalline silica and wherein the second discrete catalyst also comprises a phosphorus-containing alumina component and wherein the reaction zone is maintained at hydrocarbon conversion conditions sufficient to produce a product containing aromatic compounds.
