Abstract

Various ruthenium precursors (Ru = RuCl3, Ru2 = Ru(acac) 3, Ru3 = Ru3(CO)12) supported on bentonite were prepared by conventional impregnation method. Their catalytic performances were evaluated in the hydrogenolysis of glycerol using autoclave Parr reactor under mild reaction conditions of 150°C, hydrogen pressure 30 bar for 7 hours. Among the studied catalyst, 5% Ru/bentonite catalyst prepared from Ru and Ru3 precursor exhibited higher activity which are 79.6% and 72.5% respectively. In contrast, Ru2/bentonite prepared from Ru(acac)3 precusor gave lowest activity (41.8%). In term of selectivity to 1,2-propanediol, Ru2 and Ru3 precusor gave higher selectivity (67.0% and 66.9%) compared to Ru precursor (50.6%). These results indicated that metal precursor plays an important role on activity and selectivity of the catalyst in hydrogenolysis reaction. The catalysts were characterized by XRD, XPS, BET, FESEM-EDX and TEM, and the reasons for the high performances of the catalyst were also discussed.
