A new family of coherently grown composites of TUN and IMF zeotypes have been synthesized. These zeolites are represented by the empirical formula.NaMTAlESiOwhere 'n' is the mole ratio of Na to (Al+E), M represents a metal or metals from zinc, Group 1, Group 2, Group 3 and or the lanthanide series of the periodic table, 'm' is the mole ratio of M to (Al+E), &#x201c;k&#x201d; is the average charge of the metal or metals M, T is the organic structure directing agent or agents, and E is a framework element such as gallium. These zeolites are similar to TNU-9 and IM-5 but are characterized by unique compositions and synthesis procedures and have catalytic properties for carrying out various hydrocarbon conversion processes and separation properties for carrying out various separations.

UZM-39 aluminosilicate zeolite

A zeolite X having (a) a Si/Al framework mole ratio in a range from 1.0 to 1.5; (b) a mean diameter not greater than 2.7 microns; and (c) a relative LTA intensity not greater than 0.35, as determined by x-ray diffraction (XRD). The relative LTA intensity is calculated as 100 times the quotient of a sample LTA XRD intensity divided by a reference XRD intensity of an LTA-type zeolite material. The intensities are summed for each LTA peak with Miller indices of (2 0 0), (4 2 0), and (6 2 2) at 7.27&#xb1;0.16&#xb0;, 16.29&#xb1;0.34&#xb0; and 24.27&#xb1;0.50&#xb0; 2&#x3b8;.

Aluminosilicate X-type zeolite compositions with low LTA-type zeolite

A zeolitic binder-converted composition comprising (a) a zeolite X composition having at least a first zeolite X having a mean diameter not greater than 2.7 microns, and a second zeolite X, wherein the second zeolite X is obtained by converting a binder material to the second zeolite X and the binder material is in a range from 5 to 50 wt % of the zeolite X composition; and (b) an unconverted binder material content, after conversion to the second zeolite X is complete, in a range from 0 to 3 wt % of the zeolite X composition. The zeolite X composition has an average Si/Al framework mole ratio in a range from 1.0 to 1.5, and a relative LTA intensity not greater than 1.0, as determined by x-ray diffraction (XRD).

Binder-converted aluminosilicate X-type zeolite compositions with low LTA-type zeolite

A process for separating para-xylene from a mixture of Calkylaromatics comprises contacting the mixture of Calkylaromatics with a zeolitic binder-converted composition comprising (a) a zeolite X composition having at least a first zeolite X having a mean diameter not greater than 2.7 microns, and a second zeolite X, wherein the second zeolite X is obtained by converting a binder material to the second zeolite X and the binder material is in a range from 5 to 50 wt % of the zeolite X composition; and (b) an unconverted binder material content, after conversion to the second zeolite X is complete, in a range from 0 to 3 wt % of the zeolite X composition. The zeolite X composition has an average Si/Al framework mole ratio in a range from 1.0 to 1.5, and a relative LTA intensity not greater than 1.0, as determined by x-ray diffraction (XRD).

Para-xylene-separation with aluminosilicate X-type zeolite compositions with low LTA-type zeolite

A catalyst for converting methanol to light olefins and the process for making and using the catalyst are disclosed and claimed. SAPO-34 is a specific catalyst that benefits from its preparation in accordance with this invention. A seed material is used in making the catalyst that has a higher content of the EL metal than is found in the principal part of the catalyst. The molecular sieve has predominantly a roughly rectangular parallelepiped morphology crystal structure with a lower fault density and a better selectivity for light olefins.

Enhancement of molecular sieve performance

This invention embodies a catalyst and a process for transalkylation of C, C, and Caromatics to obtain a high yield of xylenes. The catalyst comprises a novel UZM-14 catalytic material comprising globular aggregates of crystallites having a MOR framework type with a mean crystallite length parallel to the direction of the 12-ring channels of about 60 nm or less and a mesopore volume of at least about 0.10 cc/gram. The UZM-14 catalyst is particularly active and stable in a transalkylation process.
