Claim:
A microporous crystalline zeolite having a three dimensional structure of at least SiO 2 tetrahedral units having an empirical composition in the as-synthesized form and on an anhydrous basis expressed by an empirical formula of: M m n+ R r p+ Al 1-x E x Si y O z where M is at least one exchangeable cation selected from the group consisting of alkali metal ions, alkaline earth metal ions, and rare earth metal ions, “m” is the mole ratio of M to (Al+E) and varies from greater than zero to about 2.0, R is an organoammonium cation or amine selected from the group consisting of pentaethonium ammonium, ethyltrimethylammonium (ETMA + ), hexamethonium ammonium, diquat-4, trimethypentyllammonium, choline, diethyldimethyl ammonium (DEDMA + ), trimethylpropylammonium, dimethyldiethanolammonium, tetraethyl ammonium (TEA + ), tetrapropylammonium (TPA + ), dimethylhexylamine, diethanolamine, and mixtures thereof, “r” is the mole ratio of R to (Al+E) and has a value of about 0.25 to about 5.0, “n” is the weighted average valence of M and has a value of about 1 to about 3, “p” is the weighted average valence of R and has a value of about 1 to about 2, 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 2 to about 10 and “z” is the mole ratio of O to (Al+E) and has a value determined by the equation: z =( m·n+p·r+ 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 A: TABLE A 2Θ d(Å) I/Io % 10.74-10.86 8.14-8.23 w-m 12.50-12.6 6.99-7.07 vs 16.60-16.72 5.30-5.33 s-vs 17.48-17.7 5.01-5.07 m 17.80-17.88 4.96-4.98 w 20.74-20.81 4.26-4.28 w 21.74-21.94 4.05-4.08 m-s 22.82-22.88 3.88-3.89 w-m 24.40-24.52 3.62-3.64 w 25.08-25.10 3.54-3.55 w 26.06-26.1 3.41-3.42 w-m 27.10-27.12 3.28-3.29 m 27.70-27.90 3.20-3.22 m 28.26-28.44 3.14-3.15 s-vs 30.00-30.30 2.94-2.97 m 32.58-32.64 2.74-2.75 w 33.02-33.03 2.71-2.71 w 33.28-33.29 2.69-2.70 m 33.76-33.82 2.65-2.65 w 37.48-37.56 2.39-2.40 w 41.20-42.41 2.13-2.19 w 45.96-46.01 1.97-1.98 w 51.4-52.00 1.70-1.77 w 54.05-54.26 1.69-1.70 w.
