Effects of heating rate on slow pyrolysis behaviors, kinetic parameters, and products properties of moso
bamboo were investigated in this study. Pyrolysis experiments were performed up to 700 C at heating
rates of 5, 10, 20, and 30 C/min using thermogravimetric analysis (TGA) and a lab-scale fixed bed pyrolysis
reactor. The results show that the onset and offset temperatures of the main devolatilization stage of
thermogravimetry/derivative thermogravimetry (TG/DTG) curves obviously shift toward the high-temperature
range, and the activation energy values increase with increasing heating rate. The heating rate
has different effects on the pyrolysis products properties, including biochar (element content, proximate
analysis, specific surface area, heating value), bio-oil (water content, chemical composition), and noncondensable
gas. The solid yields from the fixed bed pyrolysis reactor are noticeably different from those
of TGA mainly because the thermal hysteresis of the sample in the fixed bed pyrolysis reactor is more
thorough.
