This paper studies the influence of the support on the behavior of bimetallic CoIr-based catalysts (6.5 wt.% Co, 0.4 wt.% Ir) for hydrogen production from the oxidative steam reforming of bio-butanol raw mixture (butanol/acetone/ethanol = 6/3/1 mass ratio). Catalytic tests were carried out at 500 °C for 60 h with raw mixture/water/air/Ar = 1/10/7.5/12 molar ratio and GHSV = 7500 h(-1). Over CoIr/18CeZrO(2) and CoIr/ZnO the main process which took place was the oxidative steam reforming of the raw mixture. CoIr/18CeZrO(2) showed the better catalytic performance. Characterization of the used catalysts indicated that both active metal sintering and coke formation was prevented on the CoIr/18CeZrO(2) catalyst.
本文研究了载体对双金属 CoIr 基催化剂（Co 含量为 6.5wt.%，Ir 含量为 0.4wt.%）用于生物丁醇原料混合物（丁醇/丙酮/乙醇的质量比为 6/3/1）氧化蒸汽重整制氢反应行为的影响。在 500°C 下进行了 60 小时的催化测试，原料混合物/水/空气/Ar 的摩尔比为 1/10/7.5/12，GHSV 为 7500 h(-1)。在 CoIr/18CeZrO(2)和 CoIr/ZnO 上，主要发生的反应是原料混合物的氧化蒸汽重整。CoIr/18CeZrO(2)表现出更好的催化性能。对使用过的催化剂的表征表明，CoIr/18CeZrO(2)催化剂上阻止了活性金属烧结和积碳的形成。
