ALEXANDRIA, Va., May 12 -- United States Patent no. 12,623,909, issued on May 12, was assigned to Chevron U.S.A. Inc..

"Molecular sieve SSZ-121 with high acidity, its synthesis and use" was invented by Stacey I. Zones (San Francisco).

According to the abstract* released by the U.S. Patent & Trademark Office: "A novel synthetic crystalline aluminogermanosilicate molecular sieve material, designated SSZ-121 is provided which exhibits increased acidity. The SSZ-121 can be synthesized using 1,3-bis(1-adamantyl)imidazolium cations as a structure directing agent. The synthesis employs a boron pathway to achieve increased acid sites. The SSZ-121 of increased acidity may be used in organic compound conversion reactions and/or sorptive processes."...
