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).
Claims9
A process for transalkylation of aromatics comprising contacting a feedstream comprising C7, C9, C10 aromatics with a catalyst at transalkylation conditions to product stream comprising C8 aromatics, the catalyst comprising a support which is mordenite and topology;
- an optional element deposited on the support selected from the group consisting of platinum, tin, lead, indium, germanium, rhenium, and a combination thereof, and characterized in that the catalyst has a cylindrical shape with a maximum diameter of {fraction (1/32)} inch (0.08 cm).
