Levulinic to succinic acid transformation over Ru based catalysts

In this work ruthenium based catalysts are tested as catalytic systems for the selective oxidation of levulinic to succinic acid. Very different in nature supports have been chosen in order to elucidate the effect of their textural and acidic properties on the final catalytic activity. The influence of Ru particle size is also discussed and proposed as one of the key factors. Medium range ruthenium particles supported on relatively acid supports are the best performing systems in terms of succinic acid yield, while the most active catalysts in terms of conversion result in important carbon loss due to reagent/products full oxidation.
