Rice Husk Energy Content Enhancement by the Torrefaction Process: Characterization and Statistical Studies

Dejene Mandefro, S. Anuradha Jabasingh


Torrefaction  is the partial pyrolysis of biomass at atmospheric pressure, in an inert environment. The objective of this study is to torrefy the rice husk of Ethiopian origin in order to enhance its energy density. The optimum torrefaction temperature, holding time, and acid concentration were investigated in this study by the three-level-three-factor Box-Behnken Design (BBD) using the Design-Expert 7.0.0 software.
