Claims20
A zeolite having a mole ratio, of an oxide selected from silicon oxide, germanium oxide, and mixtures thereof to an oxide selected from boron oxide or mixtures of boron oxide with aluminum oxide, gallium oxide, or iron oxide, greater than about 20:1, and wherein the amount of boron in the zeolite is greater than 100 parts per million, and having the X-ray diffraction lines of Table 1(a).
A zeolite having a composition, as synthesized and in the anhydrous state, in terms of mole ratios of oxides as follows:
- (1.0 to 5)Q.sub.2 O:(0.1 to 1.0)M.sub.2 O:W.sub.2 O.sub.3 (greater than 20)YO.sub.2 wherein M is an alkali metal cation, W is selected from boron, or mixtures of boron with aluminum, gallium and iron, Y is selected from silicon, germanium, and mixtures thereof, Q is tricyclodecane quaternary ammonium ion and having the X-ray diffraction lines of Table 1(a).
A zeolite prepared by thermally treating the zeolite having a composition, as synthesized and in the anhydrous state, in terms of mole ratios of oxides as follows:
- (1.0 to 5)Q.sub.2 O:(0.1 to 1.0)M.sub.2 O:W.sub.2 O.sub.3 (greater than 20)YO.sub.2
- wherein M is an alkali metal cation, W is selected from boron, or mixtures of boron with aluminum, gallium and iron, Y is selected from silicon, germanium, and mixtures thereof, q is tricyclodecane quaternary ammonium ion and having the X-ray diffraction lines of Table 1(a) at a temperature from about 200.degree. C. to 820.degree. C. and having X-ray diffraction lines of Table 1(b).
