SAPO-34 Zeolites Prepared Using Calcined-MCM-41 as Silica Source

Article Preview

Abstract:

SAPO-34 molecular sieve was successfully synthesized using calcined-MCM-41 as silica source and morpholine as a template. The influence of MCM-41 content on the synthesis was investigated. The result shows that pure SAPO-34 could be obtained in a wide range of the n (SiO2)/n (Al2O3) ratio in the starting gel. Moreover, increase the n (SiO2)/n (Al2O3) ratio has a negative effect on crystallinity while high silicon incorporates into the framework of SAPO-34. Keywords: MCM-41, SAPO-34, Silicon source,
