Beschreibung
Zusammenfassung:	The present invention pertains to improved processes and catalysts for aromatization. The processes generally contacting a feed stream comprising a naphtha fraction having a C6 to C8 content with a catalyst pellet composition to form aromatic hydrocarbons. The catalyst pellet composition generally comprises a plurality of cylindrical pellets each pellet comprising a Group VIII metal on a zeolite. The pellets may have (a) a plurality of holes passing through the length of the cylindrical pellets, (b) a dome-shaped top and bottom, and (c) a plurality of semi-circular grooves along the length of the exterior of the cylinder.
