本文研究了Yolclas法和油滴法相结合制备的Cu/Al_2O_3~-、Fe/Al_2O_3~-和Cu/Fe/Al_2O_3-复合颗粒催化剂的活性，以期找到适合于三氧化硫分解反应的催化剂，作为热化学水裂解过程中的产氧反应。SO3分解在750-950℃的温度范围内进行，空速为72,000毫升/克过氧化氢酶。H在固定床反应器中。Cu/Fe/Al_2O_3-复合颗粒催化剂的催化活性优于Cu/Al_2O_3-和Fe/Al_2O_3-复合颗粒催化剂。氧化铝颗粒中的铜和铁的复合提高了催化活性，找到了[铜]/[铁]=1/2，[铜]+[铁]=0.125米的最佳配比。
In this work, the activity values of Cu/Al2O3-, Fe/Al2O3- and Cu/Fe/Al2O3-composite granule catalysts prepared by a combination of Yolclas-process and oil-drop method were studied in an attempt to find some suitable catalysts for the decomposition of sulfur trioxide as the oxygen-generating reaction in the thermo-chemical water splitting process. The SO3 decomposition was performed in the temperature range of 750-950 degrees C at a space velocity of 72,000 mL/g cat. h in a fixed bed reactor. The catalytic activity of Cu/Fe/Al2O3-COMPOSite granule catalyst was better than that of Cu/Al2O3- and Fe/Al2O3-composite granule catalysts. The composite of Cu and Fe in the alumina granules increased the catalytic activity and found the optimum ratio of [Cu]/[Fe] = 1/2 with [Cu] + [Fe] = 0.125 M. (C) 2008 Elsevier B.V.
