Abstract: The present disclosure is directed to processes for the selective separation of carbon dioxide (CO2) from multi-component feedstreams containing CO2. The processes use a potassium-form MER framework type zeolite having a stick-like morphology. The potassium is present in the zeolite as K+ in extra-framework locations, and the zeolite is essentially free of an extra-framework cation other than potassium.

Abstract: A family of new crystalline molecular sieves designated SSZ-91 is disclosed, as are methods for making SSZ-91 and uses for SSZ-91. Molecular sieve SSZ-91 is structurally similar to sieves falling within the ZSM-48 family of molecular sieves, and is characterized as: (1) having a low degree of faulting, (2) a low aspect ratio that inhibits hydrocracking as compared to conventional ZSM-48 materials having an aspect ratio of greater than 8, and (3) is substantially phase pure.
