Abstract:
A method of preparing a metal-doped zeolite catalyst with a modified topology (e.g. a pillared zeolite or a delaminated zeolite), and a method of using thereof in a process for converting an alkyl-aromatic hydrocarbon stream to BTX (benzene/toluene/xylene), wherein an enhanced pore topology in the metal-doped zeolite catalyst determines a selectivity to transalkylation of trimethylbenzene to xylene, which in turn leads to a higher xylene yield. Various embodiments of the method of preparing the metal-doped zeolite catalyst, and the process for converting the alkyl-aromatic hydrocarbon stream to BTX are also provided.

Claim (Index 6):
The process of  claim 1 , wherein the alkyl-aromatic hydrocarbon stream comprises toluene and one or more of methylethylbenzene, trimethylbenzene, dimethylethylbenzene, and tetramethylbenzene, and the process further comprises reducing a toluene content of the alkyl-aromatic hydrocarbon stream in a separation unit prior to the contacting.
