Study on the preparation and property of Pt/Ce0.5M0.5O2 (M = Zr,Ti) catalysts with high hydrothermal stability for hydrodeoxygenation(高水热稳定性加氢脱氧催化剂Pt/Ce0.5 M0.5O2 (M = Zr,Ti)的制备及其性能研究)
分别采用共沉淀法和溶胶凝胶法制备了具有高水热稳定性的Ce0.5M0.5O2 (M=Zr，Ti)载体，并通过浸渍法制得高分散Pt/Ce0.5M0.5O2（M=Zr，Ti）催化剂，分析了短链脂肪醇作为氢供体用于香兰素加氢脱氧反应的催化性能.实验结果表明，复合氧化物催化剂Pt/Ce0.5M0.5O2(M=Zr，Ti)具有高的水热稳定性和优良的加氢脱氧活性，且Pt/Ce0.5Zr0.5O2较Pt/Ce0.5Ti0.5O2的催化性能更胜一筹，催化剂的加氢脱氧性能与其表面的酸性质以及贵金属Pt在载体上的高度分散有关.短链脂肪醇作为含氢的有机小分子，可作为氢源替代氢气，是理想有效的氢供体....
