摘要:The effects of CrAl carrier preparation process and Pd loading methods on the catalytic activity of Cr modified Pd/Al2O3 catalyst for low concentration methane combustion were investigated,and the influence of Ce addition on the high-temperature stability of catalyst was also tested. X-ray diffraction and temperature programmed reduction were used to characterize the structure and redox ability of catalysts. The I-CrAl carrier prepared by impregnation had high specific surface area,and the pores were not blocked. Reduction treatment in the process of Pd loading significantly improved the activity of catalysts. Temperature-programmed reduction with hydrogen verified that the reduction process improved the catalyst reduction ability. Addition of Ce enhanced catalyst stability by resisting sintering of Al2O3 at high temperature.
