A PROCESS FOR PREPARING A CATALYST WITH A NON-ACIDIC BINDER AND A PROCESS FOR USING THE CATALYST TO PRODUCE AROMATICS

摘要

A process for converting C2 to C6 aliphatic hydrocarbons to aromatics and a process for preparing a catalyst for use in this process are disclosed. The catalyst contains a zeolite having a silica to alumina molar ratio greater than 20 and a pore diameter from 5Å to 6Å, 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 C6-C9 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.
