摘要
用化学镀方法制备了负载型N iB/S iO2非晶态合金催化剂,并采用ICP、BET、TEM、XRD等手段研究了N iB在S iO2表面的存在状态及非晶性质。研究了糠醇在该催化剂上加氢制备四氢糠醇的反应行为,考察了反应温度、压力、搅拌速度等因素对催化剂性能的影响。结果表明,在2.0 MPa、120℃、550 r/m in时,糠醇的转化率在99%以上,四氢糠醇的选择性可达100%。在此条件下和骨架N i的催化性能相当。
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 2.0 MPa, 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.
