| Abstract: | An effective Ni/CeO2 catalyst prepared by the polyol reduction method for degrading phenol into CH4, H2 and CO2 in supercritical water (SCW) was developed. About 80% carbon gasification efficiency can be achieved at 525 °C and 60 min with 5 wt% phenol, 0.098 kg/m3 water density and 0.5 g Ni/CeO2/g phenol catalyst, forming CH4 and H2 as the main gaseous products. Comparison study indicated that the efficiency of present Ni/CeO2 catalyst was about 20% higher than that of a commercial catalyst, i.e., Ni/SiO2 | |
