Effect of carbonization temperature on combustion reactivity of bagasse char

The combustion reactivity of bagasse chars was investigated under isothermal conditions at 400 degrees C in air. The bagasse char samples were prepared by carbonizing bagasse in a fixed bed reactor at temperatures between 500 degrees C and 800 degrees C. It was observed that raising the carbonization temperature resulted in a significant decrease in reactivity of bagasse char. This was manifested by the decrease in the values of the maximum reaction rate, average rate based on 50% burnout and conversion achieved in 30 minutes with the increase in carbonization temperature. The decrease in reactivity of bagasse char with carbonization temperature was attributed to changes in the reactive components of bagasse.
