在400摄氏度至800摄氏度的温度下测试了负载在氧化锆上的含有1重量%的Co、Cu、Fe、Ni、Pd和Pt的样品的甲烷蒸汽重整。Pt、Pd和Ni材料被发现是最活跃的。在800摄氏度下的稳定性测试表明，Pt样品是唯一稳定的催化剂，在其他样品上发生显著的碳沉积。甲烷的部分氧化和CO2重整也进行了Pt/ZrO 2催化剂上，这种材料被发现是相当稳定的条件下，这些反应。使用添加蒸汽的进料进行另外的CO2重整和部分氧化实验。H-2/CO比可以根据所使用的进料组成来操纵。在部分氧化过程中加入水蒸汽，得到了比在纯部分氧化条件下得到的更稳定的温度分布。(C)1998 Elsevier Science B.

Samples containing 1 wt% of Co, Cu, Fe, Ni, Pd and Pt supported on zirconia have been tested for the steam reforming of methane at temperatures from 400 degrees C to 800 degrees C. The Pt, Pd and Ni materials were found to be the most active. Stability tests at 800 degrees C showed that the Pt sample was the only stable catalyst, significant carbon deposition occurring on the other samples. Partial oxidation and CO2 reforming of methane were also carried out over the Pt/ZrO2 catalyst and this material was found to be quite stable under the conditions for these reactions. Additional CO2 reforming and partial oxidation experiments were carried out using feeds to which steam was added. The H-2/CO ratio could be manipulated, depending on the feed composition used. The addition of steam during partial oxidation gave a much more stable temperature profile through the catalyst bed than was obtained under pure partial oxidation conditions.
