The effect of chlorine precursor of ruthenium on the dispersion of the metal on the surface of Ru/MgF2 type catalysts has been studied. Results of the dispersion measurements performed by the static method of hydrogen chemisorption have shown that, similarly as for the majority of the known metallic catalysts, the dispersion decreases with ruthenium loading. The results permitted a determination of the optimum conditions for chemisorption measurements on ruthenium catalysts that is the measurement temp. of 100C and equilibrium time of 22 min. The size of the crystallites determined in the chemisorption study was compared with that following from electron microscope observations, and the mean size determined by the latter method proved much smaller than that found by the chemisorption method.
