摘　　要：In this study, various composite Ni-W</span>_{<span style="font-family:Verdana;">2</span>}<span style="font-family:Verdana;">C/active carbon catalysts were synthesized. W</span>_{<span style="font-family:Verdana;">2</span>}<span style="font-family:Verdana;">C was prepared by carbothermal hydrogen reduction. The metal loading of W</span>_{<span style="font-family:Verdana;">2</span>}<span style="font-family:Verdana;">C in catalyst was 30 wt.%. Carbon was impregnated with metatungstate.

Carbon was then carburized in H</span>_{<span style="font-family:Verdana;">2</span>}<span style="font-family:Verdana;"> flow, the temperature was increased from 25?C to 450?C, and then to 800?C and stayed for 4 h.
