英文摘要A series of catalysts composed of WO3, gamma-Al2O3 and HY were prepared to study the effects of preparation procedure and tungsten loading on their catalytic performances for the metathesis between ethene and 2-butene to propene. The catalysts are characterized by X-ray diffraction (XRD), temperature-programmed desorption of ammonia (NH3-TPD), temperature-programmed reduction of hydrogen (H-2-TPR), N-2 adsorption, UV-vis and UV resonance Raman techniques. The results reveal that the catalytic activity is determined by the structure of supported tungsten oxide species. Based on the correlation between the activity and structure of tungsten oxide species, the isolated tetrahedral oxide species are suggested to be the active sites precursors, which exhibit characteristic Raman band at 970 cm(-1).
