A new family of coherently grown composites of TUN and IMF zeotypes has been synthesized and shown to be effective catalysts for aromatic transalkylation reactions. These zeolites are represented by the empirical formula.NaMTAlESiOwhere M represents a metal or metals from zinc or Group 1 (IUPAC 1), Group 2 (IUPAC 2), Group 3 (IUPAC 3) or the lanthanide series of the periodic table, T is the organic directing agent derived from reactants R and Q where R is an A,&#x3a9;-dihalosubstituted alkane such as 1,4-dibromobutane and Q is at least one neutral amine having 6 or fewer carbon atoms such as 1-methylpyrrolidine. E is a framework element such as gallium. The process involves transalkylation of a feedstream comprising one or more of C, C, Cand C+ aromatics to obtain a transalkylation product stream having an increased concentration of Caromatics relative to that of the feedstream.

A new family of aluminosilicate zeolites designated UZM-44 has been synthesized. These zeolites are represented by the empirical formula.NaMTAlESiOwhere 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 C, C, Cand C+ aromatics to obtain a transalkylation product stream having an increased concentration of Caromatics relative to that of the feedstream.

One exemplary embodiment can be a process for facilitating a transfer of a metal catalyst component from at least one donor particle to at least one recipient particle in a catalytic naphtha reforming unit. The process can include transferring an effective amount of the metal catalyst component from the at least one donor particle to the at least one recipient particle under conditions to effect such transfer to improve a conversion of a hydrocarbon feed.
