Selective conversion of furfural to cyclopentanol over cobalt catalysts in one step

A series of cobalt catalysts with different supports were prepared for the selective conversion of biomassderived furfural to cyclopentanol（CPL） in one step.The best CPLyield was 82 mol%at 160 ℃,2 MPa H2,4 h when cobalt was supported on ZrO2-La2O3.The supports were characterized by X-ray diffraction...

Description
Summary:A series of cobalt catalysts with different supports were prepared for the selective conversion of biomassderived furfural to cyclopentanol（CPL） in one step.The best CPLyield was 82 mol%at 160 ℃,2 MPa H2,4 h when cobalt was supported on ZrO2-La2O3.The supports were characterized by X-ray diffraction（XRD）and temperature-programmed desorption of ammonia（NH3-TPD）.The XRD results indicated that the more stable t-ZrO2 formed by doping La2O3.The amount of acid sites of the catalyst increased,too.The influences of parameters such as reaction temperature,hydrogen pressure,and reaction time on the catalytic activity were also investigated.The polymer formed during the reaction may cause the deactivation of the Co/ZrO2-La2O3 catalyst.This work provides a possibility to prepare the stable t-ZrO2and apply with cobalt metal for biomass valorization.
