Abstract
High-performance catalysts for partial oxidation (POM) and dry reforming of methane (DRM) into synthesis gas with a yield of more than 90% have been developed. The GC, XRD, SEM, TGA, and TEM methods of analysis demonstrate that the catalysts generated from presynthesized SmCoO3 and PrNi0.5Co0.5O3 materials exhibited high catalytic performance in DRM and contained nanoparticles of cobalt and nickel metals and samarium or praseodymium oxides. Due to the method employed in this study for SmCoO3 the catalyst prepared from this precursor showed higher syngas selectivity, both in DRM and POM, than catalysts with similar compositions prepared by a citrate method. It was also demonstrated that the PrNi0.5Co0.5O3 catalyst prereduced in hydrogen was more efficient in POM than the sample reduced in the reagent flow.

用于甲烷部分氧化和干重整制合成气的新型高性能催化剂
摘要
已经开发出用于甲烷部分氧化（POM）和干法重整（DRM）成合成气的高性能催化剂，收率超过90%。GC、XRD、SEM、TGA 和 TEM 分析方法表明，由预合成的 SmCoO 3和 PrNi 0.5 Co 0.5 O 3材料生成的催化剂在 DRM 中表现出高催化性能，并且含有钴和镍金属以及钐或镨氧化物的纳米颗粒. 由于本研究中对 SmCoO 3采用的方法，由该前体制备的催化剂在 DRM 和 POM 中显示出比通过柠檬酸盐法制备的具有相似组成的催化剂更高的合成气选择性。也证明了 PrNi在氢气中预还原的0.5 Co 0.5 O 3催化剂在 POM 中比在试剂流中还原的样品更有效。
