In this study, various composite Ni-W2C/active
carbon catalysts were synthesized. W2C was prepared by carbothermal
hydrogen reduction. The metal loading of W2C in catalyst was 30
wt.%. Carbon was impregnated with metatungstate. It was dried at 120?C for 12 h. Carbon was then carburized in H2 flow, the temperature was increased from 25?C to 450?C, and then to 800?C and stayed for 4 h. The W2C/active
carbon was treated with H2SO4 to create more function
groups on the surface. Ni-W2C/active carbon was prepared by
incipient-wetness impregnation method. After calcination and reduction
processes in H2 flow, Ni-W2C/active carbon catalyst was
obtained. The reaction of cellulose to
ethylene glycol in one step was carried out in a batch reactor under the
following condition: 1 g cellulose, 0.3 g catalyst, 100 ml H2O, 4-6 MPa H2, 220?C -280
