英文摘要A series of 3 0Mo/MCM-22 Al2O3 catalysts with gamma-Al2O3 contents in the range of 0-100 wt% were prepared and applied in the metathesis reaction of ethene and butene-2 Addition of gamma-Al2O3 did not affect the structure of MCM 22 zeolite as evidenced by XRD and N-2 adsorption measurements It was deduced from TPR experiments that gamma-Al2O3 phase favored the formation of polymolybdate or multilayered Mo oxide, while more Al-2(MoO4)(3) species were generated over MCM 22 zeolites Alumina content in the support was directly related to the metathesis activity of ethene and butene-2 to propene Mo species with higher valence (Mo6+ or Mo5+) contributed more to the excellent performance of catalyst than metallic Mo The best catalyst activity and stability was obtained over 3 0Mo/(MCM-22-30%Al2O3) under the reaction condition of 1 0 MPa and 125 degrees C using N-2 as the pretreatment gas
