摘　　要：报道了经硫化的Fe/γ-Al_2O_3对长链正构烯烃中双烯选择加氢性能的影响,通过硫含量与加氢性能的考察和使用TPR和穆斯堡尔谱仪对样品的测试,发现样品中的Fe_(1-x)S_(0<x<1)物相与双烯选择加氢的性能直接相关,Fe_(1-x)S量的增多会使加氢活性增高。本文认为双烯选择加氢的活性物类应是Fe_(1-x)S物相,而硫化是形成这种活性物类的必要步骤。A new type of Fe/γ-Al_2O_3 catalyst is developed for selective hydrogenation of diolefins in linear internal olefins. The performance of the catalyst is featured by its excellent activity and good selectivity.The properties of the activated catalyst are investigated by temperature program reduction(TPR) and Mossbauer spectroscopy (MS). The results indicate that before sulfurization the iron on the support is Fe_2O_3 phase. When the catalyst is sulfurized Fe_2O_3 phase changes into Fe_(1-x)S phase. Increase in selectivity of catalyst occurs with increase of Fe_(1-x)S phase.
