Chen, Han published the artcileCatalytic Transfer Hydrogenation of Ethyl Levulinate to γ-Valerolactone Over Ni Supported on Equilibrium Fluid-Catalytic-Cracking Catalysts, Related Products of esters-buliding-blocks, the main research area is catalytic transfer hydrogenation ethyl levulinate gamma valerolactone.
Nickel supported on equilibrium fluid-catalytic-cracking catalysts (Ni/E-cats) were prepared by a simple grinding-pyrolysis method and employed for the transfer hydrogenation of Et levulinate (EL) to γ-valerolactone (GVL). 96.2% selectivity of GVL and 90.3% conversion of EL were obtained at 180°C for 6 h over 30-Ni/E-cat. Through XRD, N2 adsorption-desorption, NH3-TPD and SEM anal., the high activity of the 30-Ni/E-cat catalyst was attributed to its dispersed Ni metal active centers and available acidic sites. Catalytic probe test revealed that metal and acid sites of Ni/E-cat played a synergistic catalytic role in the synthesis of GVL in 2-propanol, where Ni metal sites contribute to the hydrogenation of ketone group in EL, and acid sites of E-cat promoted the lactonization of intermediate ethyl- or iso-Pr 4-hydroxyvalerate. Two reaction pathways and synergistic mechanism were proposed in this catalytic system. Moreover, Ni/E-cat catalyst exhibited good stability up to four cycles without obvious loss of catalytic activity.
