Claims19
A zeolite having a mole ratio greater than about 20 of an oxide of a first tetravalent element to an oxide of a second tetravalent element which is different from said first tetravalent element, trivalent element, pentavalent element or mixture thereof and having, after calcination, the X-ray diffraction lines of Table II.
A zeolite having a mole ratio greater than about 20 of an oxide selected from the group consisting of silicon oxide, germanium oxide and mixtures thereof to an oxide selected from aluminum oxide, gallium oxide, iron oxide, boron oxide, titanium oxide, indium oxide, vanadium oxide and mixtures thereof, and having, after calcination, the X-ray diffraction lines of Table II.
A zeolite having a composition, as synthesized and in the anhydrous state, in terms of mole ratios as follows:
- YO2/WcOd >20 M2/n/YO2 0.01-0.03 Q/YO2 0.02-0.05
- wherein Y is silicon, germanium or a mixture thereof;
- W is aluminum, gallium, iron, boron, titanium, indium, vanadium or mixtures thereof;
- c is 1 or 2;
- d is 2 when c is 1 or d is 3 or 5 when c is 2;
- M is an alkali metal cation, alkaline earth metal cation or mixtures thereof;
- n is the valence of M;
- and Q is a N-butyl-N-cyclooctylpyrrolidinium cation or N-propyl-N-cyclooctylpyrrolidinium cation.
A method of preparing a crystalline material comprising an oxide of a first tetravalent element and an oxide of a second tetravalent element which is different from said first tetravalent element, trivalent element, pentavalent element or mixture thereof, said method comprising contacting under crystallization conditions sources of said oxides and a templating agent comprising a N-butyl-N-cyclooctylpyrrolidinium cation or N-propyl-N-cyclooctylpyrrolidinium cation.
