  • Zeolite LZ-276 and process for preparing same
    Patent number: 5248491
    Abstract: A novel aluminosilicate zeolite molecular sieve, denominated LZ-276, having effective pore diameters in the small to medium size range and possibly being topologically related to zeolite Phi, is synthesized hydrothermally in the TEAOH-Na.sub.2 O--SiO.sub.2 --Al.sub.2 O.sub.3 --H.sub.2 O system at a temperature of from 100.degree. C. to 150.degree. C.
    Type: Grant
    Filed: December 20, 1991
    Date of Patent: September 28, 1993
    Assignee: UOP
    Inventors: Gary W. Skeels, Marilyn R. Sears
  • Zeolite LZ-277 and process for preparing same
    Patent number: 5192522
    Abstract: A novel aluminosilicate zeolite, denominated LZ-277 is synthesized hydrothermally from aqueous gels in the Na.sub.2 O--Al.sub.2 O.sub.3 --SiO.sub.2 system and in the absence of an organic templating agent. The as-synthesized LZ-277 has a chemical composition on an anhydrous basis expressed in terms of molar oxide ratios of:1.0.+-.0.1 Na.sub.2 O:Al.sub.2 O.sub.3 :3-15 SiO.sub.2and has a low adsorptive capacity for SF.sub.6 compared with the prior known, and possibly topologically related, zeolite Phi.
