Abstract
The objective of this study is to investigate the effects of heating rate on pyrolysis of wet biomass. Pyrolysis experiments were performed on dried samples (1 wt% moisture), air-dried samples (8 wt% moisture), and wet samples (16 wt% moisture) of corn straw. Biomass pyrolysis consisted of three stages, namely, moisture evaporation, main devolatilization, and continuous slight devolatilization. As the heating rate increased, the thermogravimetric/derivative thermogravimetric curves moved toward the high-temperature section, and average devolatilization rates increased. The Coats–Redfern method was used for kinetics analysis. The activation energy, which ranged from 63.5 to 70.8 kJ/mol, increased as the heating rate increased.
