  • Shaped catalysts for transalkylation of aromatics for enhanced xylenes production
    Patent number: 6815570
    Abstract: A catalyst, a process for using the catalyst whereby the catalyst effectively transalkylates C7, C9, and C10 aromatics to C8 aromatics are disclosed. The catalyst comprises a support such as mordenite plus a metal component. The catalyst provides an enhanced life and activity for carrying out the transalkylation reactions at relatively low temperatures. This is achieved by reducing the maximum particle diameter of cylindrical pellets to {fraction (1/32)} inch (0.08 cm) or a trilobe to {fraction (1/16)} inch (0.16 cm).
