ABSTRACT:
A process is provided for modifying ZSM-5 type zeolite catalysts with sulfur-based treating agents in order to enhance the para-selective properties of such catalysts for the conversion of aromatic materials to dialkyl-substituted benzene compounds. Sulfur-based treating agents include hydrogen sulfide and sulfur dioxide. Catalyst compositions so treated can be used in alkylation, transalkylation or disproportionation processes to provide product mixtures having exceptionally high concentrations of the para-dialkylbenzene isomer.
