This paper reports the hydrogen production through the steam reforming of a bioresource-derived butanol mixture (butanol:acetone:ethanol=6:3:1 mass ratio) over supported cobalt-based catalysts. The support plays an important role for the catalytic behavior and Co/ZnO exhibits the best catalytic performance compared to Co/TiO(2) and Co/CeO(2). Moreover, a higher hydrogen yield is obtained over bimetallic Co-Ir/ZnO, which shows an increase in H(2) selectivity and a decrease in CH(4) selectivity under steam reforming conditions, compared to Co/ZnO. Raman results of the used catalysts indicate that the addition of Ir could prevent the coke formation to prolong the catalyst stability.
本文报道了在负载型钴基催化剂上通过生物质衍生的丁醇混合物（丁醇：丙酮：乙醇= 6：3：1 质量比）的蒸汽重整制氢。载体对催化性能起着重要作用，与 Co/TiO(2) 和 Co/CeO(2) 相比，Co/ZnO 表现出最好的催化性能。此外，与 Co/ZnO 相比，双金属 Co-Ir/ZnO 在蒸汽重整条件下具有更高的氢气产率，表现出更高的 H(2)选择性和更低的 CH(4)选择性。使用后的催化剂的拉曼结果表明，添加 Ir 可以防止积碳形成，从而延长催化剂的稳定性。
