| 英文摘要 | Partial oxidation of methane (pom) was studied in this work. the supported nickel catalysts were prepared by the coprecipitation-impregnation method. the influence of the molar ratio of ce/ti, the calcination temperature, and the content of active component were investigated during the process of preparation. the results show that the mixed oxides of the ce-ti-o-supported ni catalysts exhibited high catalytic activity and stability. among the catalysts investigated, the highest catalytic activity was observed over 10 wt.% nio/ce0.50ti0.50o2-700 degrees c which showed excellently stable performance during 100 h on stream at 750 degrees c. the catalysts were characterized by dta/tg, bet, xrd, and tpr. xrd and tpr results confirmed that the nio in all catalysts was highly dispersed. there was no nio but only nitio3 in the nio/tio2 catalyst, due to the reaction between nio and tio2. nitio3 is harder to be reduced to ni-0 than nio. the addition of ceo2 could form a solid solution of ce-ti-o, which was able to restrain the reaction between nio and tio2 and improve the storage capacity and mobility of oxygen. it was shown that ni-0 reduced from nitio3 was active for the pom reaction.
