NiB/SiO2非晶态合金催化剂用于糠醇加氢制四氢糠醇的研究

NiB/SiO2 amorphous alloy catalyst was prepared by power electroless plating method and characterized by ICP, BET, TEM and XRD techniques. The catalytic performance of NiB/SiO2 was investigated for the hydrogenation of furfuryl alcohol（FA）to tetrafurfural alcohol（THFA）. The effects of operation conditions, such as reaction temperature, pressure, stirring rate were carefully studied, and the proper conditions were determined as the following: pressure 2.0MPa, temperature 120℃, stirring rate 550r/min. A typical result with FA conversion of 99% and THFA selectivity of 100% was obtained under such conditions, which is close to that of Raney Ni.
