| 摘 要： | 采用硝酸盐溶液共浸渍薄水铝石制备了不同Ni含量的Ni/CeO2/Al2O3催化剂,并采用X射线衍射、N2物理吸附和程序升温还原等手段对其进行了表征.结果表明,Ni和CeO2物种之间存在较强的相瓦作用,CeO2的加入有利于NiAl2O4还原成金属Ni,而金属Ni又促进了CeO2还原并与Al2O3反应形成CeAlO3.详细...

| Abstract: | Ni/CeO2/Al2O3 catalyst samples with different Ni contents were prepared by co-impregnating boehmite with aqueous solution of cerium and nickel nitrates and characterized by X-ray diffraction, N2 adsorption, and temperature-programmed reduction. It was found that there was a strong interaction between Ni and CeO2 species. Addition of CeO2 promoted the reduction of NiAl2O4 to metal Ni, while nickel species in turn promoted the reduction of CeO2 and reacted with Al2O3 to CeAlO3. The pre-reforming of commercial... |
