Abstract:
A fluidized bed process for producing para-xylene via toluene and/or benzene methylation with methanol using a dual function catalyst system. A first catalyst accomplishes the toluene and/or benzene methylation and a second catalyst converts the by-products of the methylation reaction or unconverted methylating agent, improves the yields of the desired products, or a combination thereof. The inclusion of the second catalyst can suppress the C 1 -C 5  non-aromatic fraction by over  50 % and significantly enhance the formation of aromatics.

Claim (Index 14):
A process for producing para-xylene, the process comprising:\n (a) providing a core-shell catalyst comprising a discontinuous layer of shell crystals covering at least a portion of the external surface of core crystals in a fluidized bed reactor, wherein the shell crystals comprise ZSM-5 having a silica/alumina molar ratio of at least 200, as measured prior to any steaming of the catalyst, and phosphorus or a compound thereof, wherein the catalyst has been steamed at a temperature of at least 900\u00b0 C., wherein said steamed catalyst has a Diffusion Parameter for  2 , 2  dimethylbutane of about 0.1-15 sec \u22121  when measured at a temperature of 120\u00b0 C. and a 2,2 dimethylbutane pressure of 60 torr (8 kPa), wherein the core crystals comprise ZSM-5; (b) alkylating C 6+  aromatic hydrocarbons with an alkylating agent selected from methanol, dimethyl ether, and mixtures thereof, in the presence of the shell crystals; and (c) converting olefins and/or paraffins formed in step (b), unconverted alkylating agent, and unconverted C 6+  aromatic hydrocarbons to para-xylene in the presence of the core crystals.
