摘要：

Two series of supported ruthenium catalysts were prepared and characterized in a pulse chromatographic reactor. One series was obtained by exchange of silica in basic solution with the Ru(NH3)6Cl3 COMPlex, and the other by impregnation of high-area activated charcoal with RuCl3 solutions. The dispersion of ruthenium on silica is measured by oxygen chemisorption at 298 K (OC298) and the total metal content after complete metal oxidation at 723 K (OC723). For charcoal-supported catalysts, these techniques were modified to account for the reductive properties of the support. Metal dispersion was obtained from both OC298 and a temperature-programmed hydrogen titration of oxygen adsorbed at 298 K (TPHT). The total metal content was deduced from the temperature-programmed reduction of the precursors.
