Abstract
This invention relates to hydrocarbon conversion processes using a new family of crystalline aluminosilicate compositions designated the UZM-27 family. These include the UZM-27 and UZM-27HS which have unique structures. UZM-27 is a microporous composition which has a three-dimensional structure and is obtained by calcining the as synthesized form designated UZM-27P. UZM-27HS is a high silica version of UZM-27 and includes an essentially pure silica version of UZM-27.
Claims7
A hydrocarbon conversion process comprising contacting a hydrocarbon stream with a crystalline microporous zeolitic composition at hydrocarbon conversion conditions to give a converted product, the crystalline zeolitic microporous composition having a three-dimensional framework composed of at least tetrahedral SiO2 units and an empirical composition on an anhydrous basis expressed by the empirical formula of:
- Mmn+Al1−xExSiyOz
- where M is at least one exchangeable cation selected from the group consisting of hydrogen ion, alkali, alkaline earth, and rare earth metals, “m” is the mole ratio of M to (Al+E) and varies from 0.05 to about 10.0, “n” is the weighted average valence of M and has a value of about 1 to about 3, 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 10 to about 35 and “z” is the mole ratio of O to (Al+E) and has a value determined by the equation:
- z=(m•n+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 B:
