Abstract
A sulfonated active carbon supported Ru catalyst was prepared and tested in hydrodeoxygenation of acetophenone. The catalysts were characterized by XRD, TEM, N2 adsorption and NH3-TPD. The influences of reaction parameters on the conversion and selectivity were studied. An acetophenone conversion of 100% with total 90% selectivity of deoxygenated products was achieved at 150°C over this catalyst, which was more active than the active carbon (AC) or SiO2 supported Ru catalysts. The enhanced performance of sulfonated AC supported Ru was attributed to the stronger acid sites and the better dispersion of Ru species. Moreover, such a catalyst was stable under the current reaction conditions and can be reused several times without obvious loss of activity.
