| 英文摘要 | the hydrogen desorbed at high temperature (high-temperature hydrogen) over the hydrogen reduced catalyst ni/la2o3/alpha-al2o3 was observed by h-2 temperature-programmed desorption. kinetic experiments show that the activity of the reforming reaction is initially increased with the amount of high-temperature hydrogen in ni/la2o3/alpha-al2o3 and finally reaches a constant value due to the in situ generation of the high-temperature hydrogen. pulse results indicate that the high-temperature hydrogen in ni/la2o3/alpha-al2o3 is prone to form ch. species with high x values, which has higher activity for the reaction of chx with co2. the ni/la2o3/alpha-al2o3 catalyst with plenty of high-temperature hydrogen can increase the x values of chx species and decrease the activation energy for the reaction between chx and co2, leading to a higher reaction rate. the addition of la2o3 on the ni/alpha-al2o3 catalyst promotes the reverse water-gas shift reaction and slightly improves the activation of co2. la2o3 also increases the amount of high-temperature hydrogen and its stability, resulting in higher x values of chx species and improving the reforming reaction rate. |
