氧化钴/高炉渣催化剂的丙烷氧化脱氢性能

Catalytic performance of oxidative dehydrogenation of propane to propene over the cobalt oxide/titanium-bearing blast furnace slag catalyst

以攀钢高炉渣为载体,采用固体研磨法负载氧化钴,制备了氧化钴/高炉渣负载型催化剂,并以XRD、H2-TPR技术对催化剂进行表征,研究了其对丙烷氧化脱氢制丙烯反应的催化性能。实验结果表明氧化钴负载在高炉渣上提高了丙烯选择性,氧化钴的负载量为20%时催化剂表现较好的催化性能,在550℃时丙烷转化率为28.80%,丙烯选择性为35.51%。本实验为资源综合利用及减少环境污染提供了新方法。

A series of the cobalt oxide/titanium-bearing blast furnace slag （ in Panzhihua Iron ＆ Steel Co ） supported catalysts were prepared by solid state grinding method and characterized by X-ray diffraction （XRD） and H2-TPR. Their catalytic behavior for the oxidative dehydrogenation （ODH） of propane to propene were also investigated. The results show that the high selectivity of propene on blast furnace slag supported catalyst made by solid state grinding method, that cobalt oxide load to 20% catalyst has a good catalytic performance for ODH of propane, 28.80% conversion of C3H8 and 35.51% selectivity of C3H6 were obtained over the catalyst under 550℃. The study provided a new way in comprehensively utilizing resources and reducing environmental pollution.
