摘要： 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.

摘要： Catalyst composition which comprises a first zeolite having a BEA* framework type and a second zeolite having a MOR framework type and a mesopore surface area of greater than 30 m2/g is disclosed. These catalyst compositions are used to remove catalyst poisons from untreated feed streams having one or more impurities which cause deactivation of the downstream catalysts employed in hydrocarbon conversion processes, such as those that produce mono-alkylated aromatic compounds.

摘要： A new family of crystalline microporous metalloalumino(gallo)phosphosilicates designated MeAPSO-83 has been synthesized. These metalloalumino(gallo)phosphosilicates are represented by the empirical formula of: Rp+rA+mM2+wExPSiyOz where A is an alkali metal such as potassium, R is an quaternary ammonium cation such as ethyltrimethylammonium, M is a divalent metal such as Zn and E is a trivalent framework element such as aluminum or gallium. This family of metalloalumino(gallo)phosphosilicate materials are stabilized by combinations of alkali and quaternary ammonium cations, enabling unique, high charge density compositions. The MeAPSO-83 family of materials have the BPH topology and have catalytic properties for carrying out various hydrocarbon conversion processes and separation properties for separating at least one component.
