Abstract: Using commercial tungsten oxide as carrier, a series of tungsten fund metal catalysts were prepared and their catalytic properties were investigated by controlling the preparation process and activation method. Results showed that the Ru-Ni/WO₃ catalyst(Ru loading 2%, Ni loading 20%), which was first impregnated with Ni and then loaded with Ru using sodium borohydride liquid-phase activation, exhibited better catalytic properties for cellulosic hydrogenolysis to ethylene glycol(EG). 86% cellulosic conversion and 63% ethylene glycol selectivity were obtained at 240 ℃ and 4 MPa H₂ pressure for 4 h. Subsequently, the characterizations of XRD, SEM, Raman, and XPS also employed to investigate the mechanism of the influence of catalyst composition and structure on its catalytic performance and product distribution. The results showed that bimetallic catalyst with Ni and Ru dipped step by step, and then actived by sodium borohydride liquid-phase reduction was easier to be reduced than the catalyst with normal dipping and hydrogen thermal reduction activation, and showed higher surface area and better dispersion of metal, with more surface defects and acid sites, thus was conducive to the occurrence of cascade reaction for cellulose to ethylene glycol.
