英文摘要: Selective oxidation of natural gas to yielding syngas was investigated over rare earth promoted nickel catalysts. It was found that the rare earth oxides like Y2O3, CeO2 were good promoters for better product yields and selectivities. The operating parameters could have an important influence on the catalyst performances, and the syngas content (CO/H-2) could arrive to 97.68% in the reaction with a space velocity of 1.5x10(5) h(-1) CH4 and at 870 degrees C. The promoted catalysts were studied by XRD, TPR and XPS techniques, the ceria could suppress the growth of nickel crystallites, enhancing the catalyst stability and the catalytic performances.
