Effect of Addition of Ce on Fe–K Mixed Oxide Catalyst in Dehydrogenation of Ethylbenzene
Ethylbenzene dehydrogenation Cerium addition Iron oxide catalyst Surface area
2010/9/8
Dehydrogenation of ethylbenzene was evaluated with Fe–K and Fe–Ce–K mixed oxide catalysts to examine the addition effect of Ce. Fe–Ce mixed oxide was prepared by co-precipitation of Fe and Ce nitrate ...
Steam Reforming of Ethanol over Co/La1-xSrxBO3 (B = Al, Cr, Mn, Fe) Catalysts
Steam reforming Ethanol Hydrogen production Perovskite Lattice oxygen
2009/8/4
The steam reforming of ethanol for producing hydrogen was evaluated over 5 wt% Co catalysts supported on perovskite-type oxides, La1-xSrxBO3 (B = Al, Cr, Mn, Fe, x = 0-0.2) at 823 K with a molar H2O/C...
Fe/炭黑、Ni/炭黑催化剂对渣油加氢反应的影响
催化剂载体 炭黑 渣油 生焦
2008/3/2
摘要使用模型化合物在微型反应釜中研究了载体炭黑对渣油内部氢转移反应的影响。结果表明，炭黑可以明显地促进四氢萘到蒽的氢转移反应。使用等体积浸渍法制备了Fe/炭黑、Ni/炭黑催化剂并对Fe/炭黑催化剂进行了XRD、SEM表征，结果表明，金属硫化物附着在炭黑颗粒的表面，直径为1μm左右。在高压反应釜中研究了载体炭黑和以炭黑为载体的催化剂对克拉玛依常压渣油430℃加氢反应的影响，并于传统的水溶性分散型催化...
