Abstract:
A process is described for producing paraxylene, in which an aromatic hydrocarbon feedstock comprising benzene and/or toluene is contacted with an alkylating reagent comprising methanol and/or dimethyl ether in an alkylation reaction zone under alkylation conditions in the presence of an alkylation catalyst to produce an alkylated aromatic product comprising xylenes. The alkylation catalyst comprises a molecular sieve having a Constraint Index≤5, and the alkylation conditions comprise a temperature less than 500° C. Paraxylene may then be recovered from the alkylated aromatic product.

Claim (Index 12):
A process for producing paraxylene, the process comprising:\n (a) contacting an aromatic hydrocarbon feed comprising toluene with an alkylating reagent comprising methanol in at least one alkylation reaction zone in the presence of an alkylation catalyst free of hydrogenation metals and rare-earth metals and comprising a molecular sieve of the MWW framework structure and under alkylation conditions comprising a temperature from about 250\u00b0 C. to less than about 500\u00b0 C. and a pressure of 700 kPa-a to 7000 kPa-a to produce an alkylated aromatic product comprising xylenes, wherein the at least one alkylation reaction zone comprises a fixed bed of the alkylation catalyst; and (b) recovering paraxylene from the alkylated aromatic product.
