| 摘 要： | Highly dispersed Ni catalysts on spherical SiO2 were prepared by simple impregnation of Ni（acac）2, Ni-（NH3）6-n（H2O）n]^2＋, Ni（en）3]^2＋ and Ni（EDTA）]^2-. Pulse adsorption of H2 and TEM analysis results confirmed that Ni was dispersed very well on the surface of SiO2 even after calcination （4 h） and reduction （1 h） at high temperature of 800 ℃. These highly dispersed and uniquely sized Ni crystallites were more stable and more reactive for both autothermal reforming and partial oxidation of methane in fluidized reactor.

| Abstract: | Highly dispersed Ni catalysts on spherical SiO2 were prepared by simple impregnation of Ni(acac)2, Ni‐(NH3)6?n(H2O)n]2+, Ni(en)3]2+ and Ni(EDTA)]2?. Pulse adsorption of H2 and TEM analysis results confirmed that Ni was dispersed very well on the surface of SiO2 even after calcination (4 h) and reduction (1 h) at high temperature of 800 °C. These highly dispersed and uniquely sized Ni crystallites were more stable and more reactive for both autothermal reforming and partial oxidation of methane in fluidized reactor. |
