  • Hydrocarbon conversion using silicon-substituted zeolite compositions
    Patent number: 4836911
    Abstract: Crystalline zeolitic aluminosilicates having at least some of its original framework aluminum atoms replaced by extraneous silicon atoms and having a mole ratio of oxides in the dehydrated state of(0.85-1.1)M.sub.2/n O: Al.sub.2 O.sub.3 : xSiO.sub.2wherein M is a cation having a valence of "n"; "x" has a value greater than 6.0; has an x-ray powder diffraction pattern having at least the d-spacings of Table A; and has extraneous silicon atoms in the crystal lattice in the form of framework SiO.sub.4 tetrahedra. These novel zeolite aluminosilicates are employed in hydrocarbon conversion processes.
    Type: Grant
    Filed: June 30, 1986
    Date of Patent: June 6, 1989
    Assignee: UOP
    Inventors: Skeels, Gary W., Donald W. Breck, deceased, by Stephen R. Breck, heir, by George D. Breck, heir
  • Silicon substituted Y zeolite composition LZ-210
    Patent number: 4711770
    Abstract: Crystalline zeolitic aluminosilicates having at least some of its original framework aluminum atoms replaced by extraneous silicon atoms and having a mole ratio of oxides in the dehydrated state of(0.85-1.1)M.sub.2/n O:Al.sub.2 O.sub.3 :xSiO.sub.2wherein M is a cation having a valence of "n"; "x" has a value greater than 6.0; has a x-ray powder diffraction pattern having at least the d-spacings of Table A; and has extraneous silicon atoms in the crystal lattice in the form of framework SiO.sub.4 tetrahedra.

  • Silicon substituted zeolite compositions and process for preparing same
    Patent number: 4610856
    Abstract: Aluminum from AlO.sub.4 -tetrahedra of as-synthesized zeolites is extracted and substituted with silicon to form zeolite compositions having higher SiO.sub.2 /Al.sub.2 O.sub.3 molar ratios and exhibiting distinctive chemical and physical properties. The preparative procedure involves contact of the starting zeolite with an aqueous solution of a fluorosilicate salt using controlled proportions and temperature and pH conditions which avoid aluminum extraction without silicon substitution.
    Type: Grant
    Filed: February 7, 1985
    Date of Patent: September 9, 1986
