Aromatic transalkylation using UZM-39 aluminosilicate zeolite

A process for transalkylation of a feedstream comprising one or more of C7, C9, C10 and C11+ aromatics to obtain a transalkylation product stream having an increased concentration of C8 aromatics relative to that of the feedstream, comprising contacting the feedstream at transalkylation conditions with a catalyst comprising a coherently grown composite of TUN and IMF zeotypes having a three-dimensional framework of at least AlO2 and SiO2 tetrahedral units and an empirical composition in the as synthesized and anhydrous basis expressed by an empirical formula of:

• NanMmk+TtAl1-xExSiyOz
• where “n” is the mole ratio of Na to (Al+E) and has a value from approximately 0.05 to 0.5, M represents at least one metal selected from the group consisting of zinc, Group 1 (IUPAC 1), Group 2 (IUPAC 2), Group 3 (IUPAC 3), and the lanthanide series of the periodic table, and any combination thereof, “m” is the mole ratio of M to (Al+E) and has a value from 0 to 0.5, “k” is the average charge of the metal or metals M, T is the organic structure directing agent or agents derived from reactants R and Q where R is an A,Ω-dihalogen substituted alkane having from 3 to 6 carbon atoms and Q is at least one neutral monoamine having 6 or fewer carbon atoms, “t” is the mole ratio of N from the organic structure directing agent or agents to (Al+E) and has a value of from about 0.5 to about 1.5, E is an element selected from the group consisting of gallium, iron, boron and combinations thereof, “x” is the mole fraction of E and has a value from 0 to about 1.0, “y” is the mole ratio of Si to (Al+E) and varies from greater than 9 to about 25 and “z” is the mole ratio of O to (Al+E) and has a value determined by the equation:
• z=(n+k·m+3+4·y)/2
• and is characterized in that it has the x-ray diffraction pattern having at least the d-spacings and intensities set forth in Table A1:
