Supported ruthenium catalyst on nano-activated carbon (2%Ru/C) and titania (2%Ru/TiO2) were prepared by wet impregnation technique with and without ionic liquid addition (choline chloride with different Lewis acid). Mole ratio of choline chloride and Lewis acid were fixed at 1:3. Catalysts evaluation was performed by glycerol hydrogenolysis reaction at 100°C with initial hydrogen pressure 20 bars for 7 hours reaction. The results showed that supported ruthenium on activated carbon acetylene black with addition of choline chloride/zinc (II) chloride catalyst indicated 30.7% of glycerol converted to 20.6% propylene glycol and 11.4% ethylene glycol. Catalysts profile of XRD showed graphitic phase which could reduce catalyst poisoning effect. XPS analysis showed that Ru/CC-ZnCl2/C catalyst spesies was in Ru4+ state before reaction. In the meantime, mapping analysis using FE-SEM showed well dispersion of ruthenium metal on nano-activated carbon acetylene black with addition of choline chloride/zinc (II) chloride gave the highest selectivity to propanediol. Furthermore, smaller size of nano activated carbon (30-60 nm) than titania (90-120nm) analyzed by TEM may the main course in increasing the conversion of glycerol.
