摘要
A supported tungsten carbide catalyst comprises tungsten carbide as its active component and a mesoporous carbon as its support, wherein tungsten carbide is highly dispersed on the surface and in the channels of the mesoporous carbon, and the content of tungsten element is in the range from 30% to 42% by mass based on the mesoporous carbon. This catalyst can be prepared by impregnation process. This catalyst can be used for the direct catalytic conversion of cellulose to ethylene glycol under the hydrothermal conditions and at a temperature of 245°C and the hydrogen pressure of 6 MPa with high reactivity, selectivity and stability.
