Abstract:
1. A hydrocarbon conversion process comprising contacting a hydrocarbon stream with a catalyst at hydrocarbon conversion conditions to give a converted product, the catalyst comprising a modified UZM-43 microporous crystalline zeolite, wherein the modified UZM-43 has a three-dimensional framework of at least AlO 2 and SiO 2 tetrahedral units and an empirical composition on an anhydrous basis expressed by an empirical formula of: where M represents sodium or a combination of sodium and potassium exchangeable cations, “m” is the mole ratio of M to (Al+E) and varies from about 0.05 to about 5, R1 is a singly charged propyltrimethylammonium cation, “r1” is the mole ratio of R to (Al+E) and has a value of about 0.25 to about 8.0, R2 is an amine, “r2” is the mole ratio of R to (Al+E) and has a value of about 0.0 to about 5, E is an element selected from the group consisting of gallium, iron, boron and mixtures 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 5 to about 40 and “z” is the mole ratio of 0 to (Al+E) and has a value determined by the equation: and is characterized in that it has the x-ray diffraction pattern having at least the d-spacings and intensities set forth in Table A: and is thermally stable up to a temperature of at least 600° C. and has a BET surface area of less than about 420 m 2 /g wherein said modified UZM-43 microporous crystalline zeolite has an EUO-NES-NON framework structure comprising from about 33-34 wt-% EUO, 24-31 wt-% NES and 34-43 wt-% NON.
