A new family of aluminosilicate zeolites designated UZM -44 has been synthesized. These zeolites are represented by the empirical formula. NanMmk+T,Ali_xExSiyOz where M represents a metal or metals from zine, Group 1, Group 2, Group 3 and or the lanthanide series of the periodic table , 'm' is the mole ratio of M to (Al + E), T is the organic structure directing agent or agents , and E is a framework element such as gallium. UZM -44 may be used to catalyze a process for the transalkylation of a feedstream comprising one or more of Ci, C9, Cio and C11+ aromatics to obtain a transalkylation product stream having an increased concentration of C8 aromatics relative to that of the feedstream. |
