A zeolite having a mole ratio greater than about 50 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 50 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:
- ______________________________________ YO.sub.2 /W.sub.c O.sub.d >50 M.sub.2/n /YO.sub.2 0.01-0.03 Q/YO.sub.2 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 at least one substituted piperidinium or decahydroquinolinium cation, said as-synthesized zeolite having the X-ray diffraction lines of Table I.
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 and having, after calcination, the X-ray diffraction lines of Table II, said method comprising contacting under crystallization conditions sources of said oxides and a templating agent comprising a substituted piperidinium or decahydroquinolinium cation.
A process for converting hydrocarbons comprising contacting a hydrocarbonaceous feed at hydrocarbon converting conditions with a catalyst comprising a zeolite having a mole ratio greater than about 50 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 process for converting lower alcohols and other oxygenated hydrocarbons comprising contacting said lower alcohol or other oxygenated hydrocarbon under conditions to produce liquid products with a catalyst comprising a zeolite having a mole ratio greater than about 50 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.
In a process for the reduction of oxides of nitrogen contained in a gas stream in the presence of oxygen wherein said process comprises contacting the gas stream with a zeolite, the improvement comprising using as the zeolite a zeolite having a mole ratio greater than about 50 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.
