摘要：
The properties and preparation of a ruthenium-tin-alumina catalyst and its control by a combination of a complexing agent-assisted sol-gel method and an impregnation method have been investigated. It was found that the metal composition of the catalyst surface could be altered by use of the combination of the two preparation methods. Depending on the surface metal composition, the H-2-adsorption ability and the hydrogenation activity of the catalysts could also be changed.
