CLAIMS

1. A method of preparing an aluminosilicate SSZ-98 zeolite, comprising:

(a) preparing a reaction mixture containing:

(1) a source of silicon oxide;

(2) a source of aluminum oxide;

(3) a source of an alkali metal (M);

(4) a structure directing agent (Q) selected from trimethylphenylammonium cations, cationic l,4-diazabicyclo[2.2.2]octane, and combinations thereof;

(5) hydroxide ions; and

(6) water; and

(b) subjecting the reaction mixture to crystallization condition sufficient to form crystals of the zeolite.

2. The method of claim 1, wherein the zeolite is prepared from a reaction mixture comprising, in terms of mole ratios, the following:

3. The method of claim 1, wherein the zeolite is prepared from a reaction comprising, in terms of mole ratios, the following:

4. The method of claim 1, wherein the alkali metal is selected from sodium, potassium, and combinations thereof.

5. An aluminosilicate SSZ-98 zeolite comprising within its pore structure a cation selected from trimethylphenylammonium cations, cationic 1,4-diazabicyclo[2.2.2]octane, and combinations thereof.

6. The zeolite of claim 5, wherein the zeolite has a S1O2/AI2O3 mole ratio of from 10 to 50.

7. The zeolite of claim 5, wherein the zeolite has a S1O2/AI2O3 mole ratio of from 10 to 20.
