Claim:
A microporous crystalline zeolite having a three dimensional structure comprised of at least AlO 2 and SiO 2 tetrahedral units and having a composition in the as-synthesized and anhydrous form in terms of mole ratios of the elements given by M m n+ R r p+ Al (1-x) E x Si y O z (1) where M is at least one exchangeable cation selected from the group consisting of alkali and alkaline earth metals, “m” is the mole ratio of M to (Al+E) and varies from 0 to about 0.50, R is at least one organo ammonium cation selected from the group consisting of quaternary ammonium cations, protonated amines, protonated diamines, protonated alkanolamines, diquaternary ammonium cations, quaternized alkanolammonium cations and mixtures thereof, “r” is the mole ratio of R to (Al+E) and has a value of about 0.51 to about 3.0, E is an element selected from the group consisting of Ga, Fe, In, Cr, B, and mixtures thereof “x” is the mole fraction of E and varies from 0 to about 1.0, “n” is the weighted average valence of M and has a value of about +1 to about +2, “p” is the weighted average valence of R and has a value of +1 to about +2, “y” is the mole ratio of Si to (Al+E) and has a value from greater than 5.5 to about 9 and “z” is the mole ratio of O to (Al+E) and has a value determined by the equation: z =( m·n+r·p+ 3+4 ·y )/2; the zeolite characterized in that it has an x-ray diffraction pattern having at least the d-spacings and relative intensities set forth in Table A: TABLE A 2Θ d (Å) I/Io (%) 7.5-7.99 11.78-11.06 m-vs 9.54-10.06 9.26-8.79 w-m 11.5-12.1 7.69-7.31 w-m 13.25-13.79 6.68-6.42 w-vs 15.35-15.95 5.77-5.55 w-m 16.47-16.99 5.38-5.21 w-m 19.33-19.8 4.59-4.48 m-vs 20.45-20.96 4.34-4.23 w-m 21.31-21.83 4.17-4.07 w-m 23.2-23.9 3.83-3.72 m-vs* 23.55-24.25 3.77-3.67 s-vs* 24.55-25.3 3.62-3.52 m-vs 26.85-27.6 3.32-3.23 w-m 28.15-28.85 3.17-3.09 w-m 31.22-31.94 2.86-2.8 m-vs 33.37-34.15 2.68-2.62 w-m 36.05-36.49 2.49-2.46 w-m* 36.36-36.71 2.47-2.45 w-m* *Adjacent peaks can coalesce, showing one peak
