3-14　果樹剪定枝のCO₂/O₂ガス化の反応モデリング

抄録

Peach pruning is a regional woody biomass resource that could be used for gasification. Some previous studies showed that CO₂/O₂ gasification rate increases with increasing O₂ in gasifying agent and reaction temperature. In this study, the effect of O₂ concentration and reaction temperature on CO₂/O₂ gasification rate and kinetic parameters of peach pruning were clarified, as well as comparison with those for timber waste. The results showed that peach pruning char was gasified with larger rate constant, kp, and smaller structure parameter, Ψ, than for timber waste char. On the other hands, with increasing O₂ in the gasifying agent, kp decreased during CO₂/O₂ gasification, while Ψ and reaction rate, dX/dt, increased.
