Steam reforming of biomass raw fuel gas over NiO–MgO solid solution cordierite monolith catalyst

The NiO–MgO solid solution cordierite monolith catalyst was prepared by impregnation. 60 h steam reforming tests were carried out at 1023 K. TG was used to analyze the carbon deposition on the catalyst. GC and GC–MS were used to analyze the component of biomass fuel gas and tar. The results show that steam reforming can effectively improve the quality of fuel gas, H2/CO ratio can be adjusted by steam reforming. The addition of steam can also increase the activity and stability of the catalyst dramatically. The CH4 conversion reached 94%. TG shows that the addition of steam can decrease the carbon deposition on the catalyst. GC–MS result shows that most of the tar was converted to H2, CO and trace lighter component. Steam reforming can eliminate the biomass tar species more deeply than dry reforming.
