Abstract

Five types of Ru-Sn-Al2O3 catalysts were prepared by a complexing agent-assisted sol-gel, impregnation and their combination methods. The effect of preparation methods of the catalysts on their properties and formation of lactones in the hydrogenation of dicarboxylic acid derivatives were examined. The surface Sn contents of catalysts characterized by X-ray photoelectron spectroscopy depended on the preparation method in spite of almost same bulk Ru and Sn compositions measured by X-ray fluorescence analyses. TPR and CO adsorption of the catalysts also depended on preparation methods. The yield of lactone decreased in the order of sol-gel (catalyst A) > combination (catalyst B and C) > impregnation (catalyst D and E).
