Abstract

OSDA-free aluminosilicate chabazite (CHA) catalysts incorporated with metals (MeCHA) by in-situ method have been successfully synthesized using a template free green method in a fluoride medium. The incorporation of metals such as B, Ni, Fe, Zn, Ba and Mg into the CHA structure have been studied. Detailed catalysts characterizations using X-ray diffraction (XRD), nuclear magnetic resonance (NMR), field emission scanning electron microscopy (FE-SEM), and N₂ adsorption/desorption showed that MeCHA preserved inherent properties of parent chabazite zeolite. Furthermore, acidity measurement showed that acid strength was dependent on the type of metal incorporated. The MeCHA zeolites incorporated with Ni, B, Mg and Fe exhibited good activity and better selectivity as compared to parent CHA in the conversion of methanol to olefins.
