Abstract

The modelling of catalyst deactivation in liquid phase reactions was discussed. Selective hydrogenation of citral was investigated at 70°C over Ru/Al₂O₃. The catalysts were characterized by hydrogen chemisorption, temperature-programmed reduction (TPR) of hydrogen and nitrogen physisorption. Catalyst activation in citral hydrogenation was ascribed to decarbonylation reaction yielding adsorbed CO that blocked active sites.
