Fruit pruning can be expected to be used as a fuel of small-scale and high-efficiency gasification to produce heat and power. In the previous study, kinetic analyses on CO₂/O₂ gasification of fruit pruning have been performed. In this study, the characteristics of Fruit pruning chars in CO₂/O₂ gasification were evaluated by comparing that for reference biomass chars (park pruning chars and timber waste chars). Furthermore, a new kinetic model was proposed that was applicable for the pruning gasification in CO₂/O₂ atmosphere. As a result, the reactivity of several chars was different upon K content due to generating form. The n-th order extended modified random pore model (nMRPM) predicted the instantaneous reactivity better than MRPM with higher R² value (coefficient of determination) than MRPM. Moreover, nMRPM showed better coefficient of determination with higher temperatures and higher O₂ concentration.
