Abstract: A new family of coherently grown composites of TUN and IMF zeotypes have been synthesized. These zeolites are represented by the empirical formula. NanMmk+TtAl1?xExSiyOz where “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), “k” 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.

Abstract: An extruded C8 alkylaromatic isomerization catalyst is described. The catalyst has an average pore diameter in a range of about 110 ? to about 155 ? measured by BJH adsorption method and a pore volume less than about 0.62 cc/g measured by N2 porosimetry. A process for isomerizing a non-equilibrium C8 aromatic feed to provide an isomerized product is also described.

Abstract: Methods are disclosed utilizing synchrotron X-ray microscopy including x-ray fluorescence and x-ray absorption spectra to probe elemental distribution and elemental speciation within a material, and particularly a solid that may have one or more elements distributed on a solid substrate. Representative materials are relatively homogeneous in composition on the macroscale but relatively heterogeneous on the microscale. The analysis of such materials, particularly on a macroscale at which their heterogeneous nature can be observed, provides valuable insights into the relationships or correlations between localized concentrations of elements and/or their species, and concentrations of other components of the materials. Sample preparation methods, involving the use of a reinforcing agent, which are advantageously used in such methods are also disclosed.

Abstract: The present invention comprises a hydrocarbon-conversion process using an improved MgAPSO-31 molecular sieve which demonstrates a favorable combination of conversion and selectivity in aromatics conversion. The sieve has a specific combination of crystal configuration, being limited in diameter and length, specified crystallinity as measured by an X-Ray Diffraction Index (XRDI), and a narrow range of magnesium content.

Abstract: 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.

Abstract: An aluminosilicate zeolite and substituted version designated UZM-16 have been synthesized. These zeolites are prepared using benzyltrimethyl-ammonium (BzTMA) cation or a combination of BzTMA and at least one other quaternary ammonium cation These zeolites have a structure that is related to offretite, but shows structurally different and distinct features. The UZM-16 zeolites can be dealuminated to form UZM-16HS zeolites which have different acidity, porosity and ion-exchange properties. Both UZM-16 and UZM-16HS are useful in various hydrocarbon conversion processes.
