Abstract:
A microporous crystalline zeolite having a three dimensional framework of at least AlO2 and SiO2 tetrahedral units and an empirical composition on an as synthesized and anhydrous basis expressed by an empirical formula of:Mmn+Rrp+Al1âˆ’xExSiyOz where M is at least one exchangeable cation selected from the group consisting of alkali and alkaline earth metals, â€œmâ€  is the mole ratio of M to (Al+E) and varies from 0 to about 0.95, R is at least two organic cations selected from the group consisting of quaternary ammonium ions, diquaternary ammonium ions, protonated amines, protonated alkanolamines and quaternized alkanolammonium ions and further where at least one of said organic cations contains at least one organic group having at least two carbon atoms, â€œrâ€  is the mole ratio of R to (Al+E) and has a value of about 0.5 to about 1.5, â€œnâ€  is the weighted average valence of M and has a value of about 1 to about 2, â€œpâ€  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, â€œxâ€  is the mole fraction of E and has a value from 0 to about 0.5, â€œyâ€  is the mole ratio of Si to (Al+E) and varies from greater than 3.5 to about 6 and â€œzâ€  is the mole ratio of O to (Al+E) and has a value determined by the equation:z=(mÂ·n+rÂ·p+3+4Â·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 A2-&thgr;d(Ã¥)I/I0 %7.30-7.4211.9-12.1m-vsâ€‚10.3-10.52â€‚8.4-8.58m-s12.65-12.866.88-6.99w-s14.61-14.855.96-6.06w-m16.37-16.655.32-5.41w-m20.74-21.034.22-4.28w-m21.98-22.383.97-4.04m-vsâ€‚23.2-23.643.76-3.83w24.37-24.783.59-3.65vs26.51-27.00â€‚3.3-3.36m27.51-28.043.18-3.24w-m30.48-30.81â€‚2.9-2.93m31.36-31.822.81-2.85w-m32.17-33.802.65-2.78w33.80-34.602.59-2.65wâ€‚34.6-35.312.54-2.59w-m36.19-37.122.42-2.48w36.96-37.772.38-2.43w44.83-45.791.98-2.02w-mâ€‚48.1-48.931.86-1.89w48.65-49.5â€‚1.84-1.87w
