Claim:
A microporous crystalline zeolite having a three-dimensional framework of at least AlO 2 and SiO 2 tetrahedral units and an empirical composition on an anhydrous basis in terms of mole ratios of the elements of: M1 a n+ Al (1−x) E x Si y′ O z″ where M1 is at least one exchangeable cation selected from the group consisting of alkali metals, alkaline earth metals, rare earth metals, ammonium ion, hydrogen ion and mixtures thereof, a is the mole ratio of M1 to (Al+E) and varies from 0.05 to about 50, E is an element selected from the group consisting of gallium, iron, boron, chromium, indium 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 M1 and has a value of about +1 to about +3, y′ is the mole ratio of Si to (Al+E) and is greater than about 6.5 and z″ is the mole ratio of O to (Al+E) and has a value determined by the equation: z ″=( a•n+ 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 B: TABLE B 2-θ d(Å) I/I o % 6.90-7.40 12.80-11.94 w-vs 8.15-8.66 10.84-10.21 m-vs 14.10-14.70 6.28-6.02 w-vs 19.40-20.10 4.57-4.41 w-s 22.00-22.85 4.04-3.89 m-vs 24.65-25.40 3.61-3.50 w-m 25.70-26.50 3.46-3.36 w-vs.
