英文摘要: A novel route for synthesis of MCM-49/ZSM-35 composite zeolites with different compositions in a mixed amine system containing hexamethyleneimine (HMI) and cyclohexamine (CHA) has been developed. Furthermore, both MCM-49 zeolite and ZSM-35 zeolite can be successfully synthesized by adjusting the synthesis conditions in the same system. Especially, the MCM-49/ZSM-35 composites with more content of ZSM-35 zeolite can be produced under conditions of larger CHA/HMI molar ratio, higher Na(2)O/Al(2)O(3) molar ratio and longer crystallization time. The structure characterization, acid distribution and morphology of the MCM-49/ZSM-35 composite zeolites are characterized by X-ray diffraction, N(2) adsorption isotherms, NH(3)-TPD, scanning electron microscopy as well as Hp-(129)Xe NMR technology. These characterizations give obvious different pore structure of the MCM-49/ZSM-35 composite zeolites from the mechanical mixing counterpart. (C) 2009 Elsevier Inc. All rights reserved.
