Abstract
The present invention relates to new crystalline zeolite SSZ-54 prepared using a templating agent comprising N-isopropyl ethylenediamine, or a mixture of 1-N-isopropyl diethylenetriamine and isobutylamine, and processes employing SSZ-54 in a catalyst.
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 pattern of FIG. 1.
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 pattern of FIG. 1.
A zeolite having a composition, as synthesized and in the anhydrous state, in terms of mole ratios as follows:
- YO2/WcOd 25-100 M2/n/YO2 0.02-0.06 Q/YO2 0.01-0.04
- 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 comprises N-isopropyl ethylenediamine, or a mixture of 1-N-isopropyl diethylenetriamine and isobutylamine.
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 N-isopropyl ethylenediamine, or a mixture of 1-N-isopropyl diethylenetriamine and isobutylamine.
