摘要： A method is provided for treating modified ZSM-5 type zeolite catalysts with water vapor in order to enhance the aromatics conversion activity and/or the para-selective properties of such catalysts for the conversion of aromatic materials. The modified zeolites so treated are those which contain a minor proportion of a difficultly reducible oxide such as magnesium oxide, calcium oxide and/or phosphorus oxide. Such catalyst compositions can be used in alkylation, transalkylation or disproportionation processes to provide improved yields of alkylated aromatic product mixtures having exceptionally high concentrations of the para-dialkylbenzene isomer.
