A novel process for converting C 2 to C 6 aliphatic hydrocarbons to aromatics and catalyst for use in this process are disclosed. The catalyst that contains a zeolite having a silica to alumina molar ratio greater than about 20 and a pore diameter from about 5 Å to about 6 Å, an essentially non-acidic binder, and a gallium component. The binder is selected from silica, zirconia, titania, and mixtures thereof and results in a catalyst formulation having both enhanced selectivity to desired C 6 -C 9 aromatic products and improved stability compared to prior art compositions. Preferred zeolites that can be used include those of the MFI structure type, with ZSM-5 being a specific example. |
