    摘要: Crystalline microporous zeolites designated calcined UZM-22 and UZM-22HS have been synthesized. The calcined UZM-22 is represented by the empirical formula: M1′mn+Al1-xExSiyOz and UZM-22HS has an empirical formula of: M1an+Al(1-x)ExSiy′Oz″ where M1 and M1′ are exchangeable cations such as lithium or strontium and E is a framework element such as gallium. Both zeolites are obtained from an as synthesized microporous crystalline composition having an empirical formula of: Mmn+RrAl1-xExSiyOz either by calcination for UZM-22 or by various treatments such as ammonium hexafluorosilicate treatment for UZM-22HS.M is an alkali, alkaline earth, or rare earth metal such as lithium and strontium, R is a singly charged organoammonium cation such as the choline cation and E is a framework element such as gallium.

    摘要: The present invention discloses microporous UZM-5 zeolite membranes, methods for making the same, and methods of separating gases, vapors, and liquids using the same. The small-pore microporous UZM-5 zeolite membrane is prepared by two different methods, including in-situ crystallization of one or more layers of UZM-5 zeolite crystals on a porous membrane support, and a seeding method by in-situ crystallization of a continuous second layer of UZM-5 zeolite crystals on a seed layer of UZM-5 zeolite crystals supported on a porous membrane support. The membranes in the form of disks, tubes, or hollow fibers have superior thermal and chemical stability, good erosion resistance, high CO2 plasticization resistance, and significantly improved selectivity over polymer membranes for gas, vapor, and liquid separations.

    摘要: A new family of crystalline aluminosilicate zeolites has been synthesized. These zeolites are represented by the empirical formula. Mmn+Rr+Al(1-x)ExSiyOz where M represents a combination of potassium and sodium exchangeable cations, R is a singly charged organoammonium cation such as the propyltrimethylammonium cation and E is a framework element such as gallium. These zeolites are similar to MWW but are characterized by unique x-ray diffraction patterns and compositions and have catalytic properties for carrying out alkylation processes.
