摘要： 作者在文献中初步阐明了标题催化剂失活的原因,认为反应中间物或产物在选择氧化活性中心上的强吸附是催化剂结焦的原因,催化剂易还原不易再氧化的性质是催化剂活性结构永久性破坏的原因,并提出了改进催化剂的方向。本文报导钒对锑铁系催化剂的助催化作用。

Abstract: The ammoxidation of propylene using antimony-iron oxide catalyst was investigated by means of a fluidized bed reactor. The reactivity, amount of carbon deposited, and ESR spectrum data were determined, The results indicate that vanadium dopped system resists the carbon deposition, stabilizing the structure of the catalysts, and accelerates the reoxidation ratt of the reduced catalysts.
