To investigate the influence of heating rate

atmosphere and particle size on pyrolysis characteristics of corn stalk

experiments were conducted on a TA-Q500thermogravimetric analyzer.The results show that

with an increase in heating rate

the corn stalk's pyrolysis rate and the corresponding peak value increased

and the overall pyrolysis reaction became more concentrated; in nitrogen atmosphere

there was only one obvious weight loss peak on the DTG curve

while in air atmosphere

there exhibit two;the total weight loss in nitrogen atmosphere was less than that in the air atmosphere;with an increase in particle size

the initial

peak and final pyrolysis temperature of the corn stalk all increased

and the maximum weight loss rate also increased a little.
