ABSTRACT:
The present invention is directed to novel alkylated aromatic compositions, zeolite catalyst compositions and processes for making the same. The catalyst compositions comprise zeolite Y and mordenite zeolite having a controlled macropore structure. The present invention is also directed to the preparation of the catalyst compositions and their use in the preparation of novel alkylated aromatic compositions. The catalyst compositions of the present invention exhibit reduced deactivation rates during the alkylation process, thereby increasing the life of the catalysts.
