Uses for a new crystalline molecular sieve designated SSZ-98 are disclosed. SSZ-98 has the ERI framework type and is synthesized using a N,N′-dimethyl-1,4-diazabicyclo[2.2.2]octane dication as a structure directing agent. 3. The process of claim 2 , wherein the light olefins are ethylene claim 2 , propylene claim 2 , butylene claim 2 , or mixtures thereof.4. The process of claim 2 , wherein the oxygenate is methanol claim 2 , dimethyl ether claim 2 , or a mixture thereof.7. The process of claim 6 , wherein the molecular sieve contains a metal or metal ions capable of catalyzing the reduction of the oxides of nitrogen.8. The process of claim 7 , wherein the metal is lanthanum claim 7 , chromium claim 7 , manganese claim 7 , iron claim 7 , cobalt claim 7 , rhodium claim 7 , nickel claim 7 , palladium claim 7 , platinum claim 7 , copper claim 7 , zinc claim 7 , or mixtures thereof.9. The process of claim 6 , wherein the gas stream is the exhaust stream of an internal combustion engine.11. The process of claim 10 , wherein the engine is an internal combustion engine.12. The process of claim 11 , wherein the internal combustion engine is an automobile engine.13. The process of claim 10 , wherein the engine is fueled by a hydrocarbon fuel.14. The process of claim 10 , wherein the molecular sieve has deposited on it a metal selected from the group consisting of ruthenium claim 10 , rhodium claim 10 , palladium claim 10 , platinum claim 10 , and mixtures thereof.15. The process of claim 14 , wherein the metal is palladium claim 14 , platinum claim 14 , or a mixture thereof. This application claims the priority benefit of U.S. Provisional Application No. 62/020,638, filed Jul. 3, 2014, which is incorporated herein by reference.This disclosure relates to new crystalline molecular sieve designated SSZ-98, a method for preparing SSZ-98 using a N,N′-dimethyl-1,4-diazabicyclo[2.2.2]octane dication as a structure directing agent (“SDA”), and uses for SSZ-98. These materials have ...
