O-18　バナナ皮とほかのバイオマス共気化による水素生産

抄録

Co-gasification of various biomass feedstocks takes advantage of intrinsic catalytic species to improve gasification rate. In this work, banana peels (BP) were co-gasified with other biomass such as Japanese cedarwood (CW) and rice husk (RH) to produce H₂-rich fuel gas. The influences of reaction temperature and the mixing ratio on the steam co-gasification rate were studied. Since BP contains a high content of potassium (K), which could enhance the gasification of CW and RH, the gasification of CW was greatly enhanced in the presence of BP. Otherwise, the co-gasification of RH and BP showed a negative effect due to the high content of silicon (Si) in RH which tended to retard the activity of alkali compounds by the forming of alkali silicates.
