Zeolite having a one-dimensional channel system, 10-membered rings and 12-membered rings
A new crystalline aluminosilicate zeolite comprising a novel framework has been synthesized that has been designated UZM-55. This zeolite is represented by a three-dimensional framework of at least SiO 2 tetrahedral units and an empirical composition in the as-synthesized and anhydrous basis expressed by an empirical formula of: M m n+ R r Al x E y SiO z where M represents a metal or metals from zinc or Group 1 (IUPAC 1), Group 2 (IUPAC 2), Group 3 (IUPAC 3) or the lanthanide series of the periodic table, R is a structure directing agent or agents such as 1,6-bis(N-methylpiperidinium)hexane, and E is an element selected from the group consisting of gallium, iron, boron and mixtures thereof. Catalysts made from UZM-55 have utility in various hydrocarbon conversion reactions including methanol to hydrocarbons (MTH).
1. A microporous crystalline zeolite, UZM-55, having a channel system comprising 10-membered rings of tetrahedrally coordinated atoms and 12-membered rings of tetrahedrally coordinated atoms in a single channel, wherein the channel system is one-dimensional, and represented by an empirical formula:
M m n+ R r Al x E y SiO z
where M represents hydrogen or a metal or metals selected from the group consisting of zinc, Group 1 (IUPAC 1) metals, Group 2 (IUPAC 2) metals, Group 3 (IUPAC 3) metals or lanthanide series metals of the periodic table, “m” is the mole ratio of M to Si 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 3, R is a structure directing agent or agents, “r” is the mole ratio of N from the organic structure directing agent or agents to Si and has a value of about 0 to about 1.0, “x” is the mole ratio of Al to Si and has a value of from 0 to about 0.026, E is an element selected from the group consisting of gallium, iron, boron and mixtures thereof, “y” is the mole ratio of E to Si and has a value from 0 to about 0.026, and “z” is the mole ratio of O to (Al+E) and has a value determined by the equation:
z =(4+ m+ 3● x+ 3● 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 1:
