【摘要】 用镍金属制备了一整体催化剂并与负载铑和铂比较了甲烷氧化制合成气的性能。结果表明 ,镍金属催化剂上甲烷转化率、H2 和 CO的选择性与铑催化剂相当 ,而且稳定性非常好。反应中加入 H2 O和 CO2 的实验表明 ,产物中 H2 / CO的比例可以直接调节更多还原

【Abstract】 A monolithic Ni metal catalyst was prepared and its performace in the partial oxidation of methane to syngas was compared with that of supported Rh and Pt catalysts.It was shown that the Ni metal catalyst gave the similar methane conversion and selectivity to H 2 and CO as supported Ni and Rh catalysts,but had excellent stability.The results with H 2O and CO addition in the reaction indicate that H 2/CO ratio in the products can be adjusted directly in the reaction.更多还原
