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 1):
A process for converting an alkyl-aromatic hydrocarbon stream to a BTX-rich stream, comprising:\n contacting the alkyl-aromatic hydrocarbon stream with a zeolite catalyst in the presence of hydrogen gas at a temperature in a range of 200-500\u00b0 C. and at a pressure in a range of 1-3 MPa to form a product stream, wherein a molar ratio of the hydrogen gas to hydrocarbon compounds in the alkyl-aromatic hydrocarbon stream is in the range of 1:1-6:1, and wherein the zeolite catalyst comprises:\n a pillared MWW zeolite, and \n at least two metals selected from the group consisting of Pt, Re, Mo, and Ni, \n wherein the zeolite catalyst comprises micro-pores having a specific pore volume in the range of 0.05-0.1 cm 3 /g, and meso-pores having a specific pore volume in the range of 0.3-0.5 cm 3 /g; and \n wherein the contacting is carried out in a fixed-bed reactor and prior to the contacting the zeolite catalyst is placed in the fixed bed reactor, oxidized with an oxygen-containing gas and then reduced with hydrogen-containing gas, and \n separating C 5\u2212  and C 9+  hydrocarbon compounds from the product stream to form the BTX-rich stream.
