Synthesis and Characterization of SAPO-34 and NiSAPO-34 for Conversion of Methanol to Light Olefins

The influence of nickel incorporation into the framework of SAPO-34 was investigated in this study. NiSAPO-34 was acquired by the hydrothermal crystallization method and mixed of two templates. The synthesized samples were characterized by means of XRD and SEM techniques. The results confirmed formation of the pure phase by addition of the nickel salt to initial gel. The performances on methanol conversion for NiSAPO-34 catalyst were different from SAPO-34. The crystallinity and crystal size of NiSAPO-34 sample was higher than SAPO-34. As a result, the methanol conversion was enhanced on the nickel-incorporated catalyst compared with the non-metal catalyst
