Abstract
ZSM-5/SAPO-34 zeolite composites were successfully synthesized by adding ZSM-5 into SAPO-34 synthetic gel under hydrothermal synthesis conditions, and SAPO-34 as a part of the composite zeolite was synthesized from LAPONITE® as the Si source. The presence of ZSM-5 in the synthetic gel affects the nucleation and crystal growth rate, and core–shell structured zeolite composites can be formed by adding an appropriate amount of ZSM-5. LAPONITE® itself contains Li and Mg atoms which were subsequently introduced into the framework of the SAPO-34 part in the composites via depolymerization–reorganization during the process of crystallization. Furthermore, the depolymerized LAPONITE® can be converted in situ into zeolitic precursors and act as crystalline seeds under hydrothermal conditions. Compared with the ZSM-5/SAPO-34 zeolite composites synthesized from tetraethylorthosilicate (TEOS) instead of LAPONITE® as the Si source, the ZSM-5/SAPO-34 composites synthesized from LAPONITE® exhibited higher selectivity to light olefins and longer lifetime in the MTO reaction. This work provides a convenient route to the synthesis of ZSM-5/SAPO-34 zeolite composites with excellent MTO performance.

 

Sapo-34 zeolite molecular sieve

The crystal structure of SAPO-34‚ a micro pore zeolite‚ is similar to that of chabazite and has a special water absorbing capacity and bronsted acidity. This can be used as an adsorbent‚ catalyst and catalyst support in applications with low carbon olefin transfer‚ auto gas purification‚ MTO reactions‚ etc.

 

Crystal structure of SAPO-34, which is a micro pore zeolite, is similar to chabazite, have special water absorbing capacity and bronsted acidity. So this type could be used as adsorbent, catalyst and catalyst support in low carbon olefin transfer, auto gas purification, MTO reactions, etc.
