WebThe single vacancy sites on the surface of defective carbon form strong chemical bonds with ruthenium chloride and increase the electron density of ruthenium ions in the ruthenium catalyst. The deactivation rate of ruthenium catalysts in acetylene hydrochlorination is approximately linearly related to their acidity and coke deposition. WebMay 31, 2024 · Dispersion of the active phase clearly depends on the carbon texture. The activity tests conducted in H 2-rich streams with very low CO concentrations (0.5 vol% CO) have shown that the activity of Ru/carbon catalysts changes with the ruthenium particles size (d). The highest activities were obtained for ruthenium particles in the range 4–8 nm ...
