ABSTRACT:
Applicants have prepared a novel zeolite identified as LZ-281. This zeolite has the framework topology of zeolite EMT. The LZ-281 zeolite is prepared by removing framework aluminum atoms from EMC-2 zeolite while simultaneously replacing the aluminum atoms with extraneous silicon atoms. This increases the SiO.sub.2 /Al.sub.2 O.sub.3 ratio versus the starting EMC-2 zeolite and results in the LZ-281 zeolite having increased thermal stability, increased number and/or strength of acid sites and increased activity in hydrocarbon processes requiring strong acid sites.
