Abstract

A new family of coherently grown composites of TUN and IMF zeotypes have been synthesized. These zeolites are represented by the empirical formula. NanMmk+TtAl1-xExSiyOz where “n” is the mole ratio of Na to (Al+E), M represents a metal or metals from zinc, 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), “k” is the average charge of the metal or metals M, T is the organic structure directing agent or agents, and E is a framework element such as gallium. These zeolites are similar to TNU-9 and IM-5 but are characterized by unique compositions and synthesis procedures and have catalytic properties for carrying out various hydrocarbon conversion processes and separation properties for carrying out various separations.

A hydrocarbon conversion process comprising contacting a hydrocarbon with a catalytic composite at hydrocarbon conversion conditions to give a converted product, the catalytic composite 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 TUN regions and IMF regions that are coherently aligned so that the [010]TUN zone axis and the [001]IMF zone axis are parallel to each other and there is continuity of crystal planes of type (002)TUN and (060)IMF, where the indexing is referred to monoclinic C2/m and orthorhombic Cmcm unit cells for TUN and IMF respectively
wherein the hydrocarbon conversion process is selected from the group consisting of cracking, hydrocracking, alkylation of aromatics or isoparaffins, isomerization of paraffin, olefins, or poly-alkylbenzene such as xylene, trans-alkylation of poly-alkylbenzene with benzene or mono-alkylbenzene, disproportionation of mono-alkylbenzene, polymerization, reforming, hydrogenation, dehydrogenation, transalkylation, dealkylation, hydration, dehydration, hydrotreating, hydrodenitrogenation, hydrodesulfurization, methanation, syngas shift process and combinations thereof;
and
wherein the catalytic composite is characterized in that it has the x-ray diffraction pattern having at least the d-spacings and intensities set forth in Table A1:
