A catalyst composition for converting an alcohol to olefins, the catalyst composition comprising the following components: (a) a support (e.g., particles) comprising silicon and oxygen; (b) at least one of copper and silver residing on and/or incorporated into said support; and (c) at least one lanthanide element residing on and/or incorporated into said support. The catalyst may also further include component (d), which is zinc. Also described herein is a method for converting an alcohol to one or more olefinic compounds (an olefin fraction) by contacting the alcohol with a catalyst at a temperature of at least 100° C. and up to 500° C. to result in direct conversion of the alcohol to an olefin fraction containing one or more olefinic compounds containing at least three carbon atoms; wherein ethylene and propylene are produced in a minor proportion of the olefin fraction, and butenes and higher olefins are produced in major proportion.

Molecular sieves comprising intergrowths of cha and aft having an “sfw-GME tail”, at least one structure directing agent (SDA) within the framework of the molecular sieve, an intergrowth of CHA and GME framework structures, cha cavities, and aft cavities are described. A first SDA comprising either an N,N-dimethyl-3,5-dimethylpiperidinium cation or a N,N-diethyl-2,6-dimethylpiperidinium cation is required. A second SDA, which can further be present, is a CHA or an SFW generating cation. The amount of the second SDA-2 used can change the proportion of the components in the cha-aft-“sfw-GME tail”. Activated molecular sieves formed from SDA containing molecular sieves are also described. Compositions for preparing these molecular sieves are described. Methods of preparing a SDA containing JMZ-11, an activated JMZ-11, and metal containing activated JMZ-11 are described. Methods of using activated JMZ-11 and metal containing activated JMZ-11 in a variety of processes, such as treating exhaust gases and converting methanol to olefins are described.
