Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 47 words
A zeolite having a mole ratio of an oxide selected from silicon oxide, germanium oxide and mixtures thereof to an oxide selected from aluminum oxide, gallium oxide, iron oxide, boron oxide and mixtures thereof greater than about 100:1, and having the X-ray diffraction lines of Table 1.
Claim 2
Dependent Claim 47 words
A zeolite having a mole ratio of an oxide selected from silicon oxide, germanium oxide and mixtures thereof to an oxide selected from aluminum oxide, gallium oxide, iron oxide, boron oxide and mixtures thereof greater than about 100:1, and having the X-ray diffraction lines of Table 1.
Claim 3
Dependent Claim 82 words
A zeolite having a composition, as synthesized and in the anhydrous state, in terms of mole ratios of oxides as follows: (0.1 to 10)Q 2 O:(0.1 to 5.0)M 2 O:W 2 O 3 : (greater than 100) YO 2 wherein M is an alkali metal cation, W is selected from aluminum, gallium, iron, boron and mixtures thereof, Y is selected from silicon, germanium and mixtures thereof, Q is an adamantane quaternary ammonium ion and having the X-ray diffraction lines of Table 1.
Claim 4
Dependent Claim 82 words
A zeolite having a composition, as synthesized and in the anhydrous state, in terms of mole ratios of oxides as follows: (0.1 to 10)Q 2 O:(0.1 to 5.0)M 2 O:W 2 O 3 : (greater than 100) YO 2 wherein M is an alkali metal cation, W is selected from aluminum, gallium, iron, boron and mixtures thereof, Y is selected from silicon, germanium and mixtures thereof, Q is an adamantane quaternary ammonium ion and having the X-ray diffraction lines of Table 1.
Claim 5
Dependent Claim 14 words
