摘要：
Lignin was gasified in supercritical water (SCW) with Ru/C, Pt/C, Pd/C and Ni/Al7O3-SiO2. The results indicated that the gasification yield (GY) and carbon yield (CY) were dramatically improved by four nano noble metal catalysts, especially with Ru/C, which doubled the GY and CY. The reason might be that catalysts can reduce lignin and help opening-ring, which lead to efficient gasification of lignin in SCW, but further research is necessary. Four catalysts have some different selectivity to different gases, but gaseous compositions are still similar as catalysis can't change the reactions equilibrium.
