Abstract:
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/SiO2 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 550r/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.
