摘要
In this work, we have developed an in situ growth method to synthesize spherical ZSM-5/alpha-Al2O3 composite on spherical alpha-Al2O3 and investigated the morphology, structure, and properties of this composite using scanning electron microscope (SEM), powder X-ray diffraction analysis (XRD), NH3-temperature program desorption (NH3-TPD) and low temperature N-2 adsorption-desorption isotherm (BET). The results show that ca. 2.4 wt% ZSM-5 has been formed in the composite with a Si/Al ratio of 46.5 and an average particle size of 8.04 mu m. Furthermore, the formed ZSM-5 markedly enhances the surface acidity and the BET surface area of spherical alpha-Al2O3 support. (C) 2014 Elsevier B.V. All rights reserved.
