| 英文摘要 | a nano-sized fe2o3-k2o catalyst was prepared by the impregnation-thermal decomposition method and was evaluated in the ethylbenzene dehydrogenation at 520-580 degrees c under normal pressure. an ethylbenzene conversion of 71.9% with a styrene selectivity of 91.1 % was obtained at 550 degrees c, n-2/h2o/ethylbenzene molar ratio of 30.7/10/1, and whsv of 0.43 h(-1). transmission electron microscopy and x-ray diffraction results indicated that fe2o3 nanoparticles in the fe2o3-k2o catalyst are well distributed with diameters of 10-14 run. the large number of active sites in the spinel phase of the catalyst is responsible for the high catalytic activity. |
