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 20):
A catalyst composition for producing para-xylene in a fluidized or moving bed process, the catalyst comprising:\n (a) core crystals of a first medium-pore size aluminosilicate zeolite having a pore size of about 5 to about 7 Angstroms; and (b) a discontinuous layer of shell crystals of a second medium-pore size aluminosilicate zeolite covering at least a portion of the external surface of the core crystals, wherein the shell crystals may be the same as or different from the core crystals, wherein the shell crystals are configured to accomplish toluene methylation and the formation of olefin and/or paraffin by-products when toluene is reacted with an alkylating agent in the presence of the shell crystals; and wherein the core crystals are configured to convert the olefin and/or paraffin by-products to para-xylene.
