The pyrolysis tests of corn stalks have been carried out by using thermogravimetric and differential analysis instruments at different temperature rise rate.Results of test show that the pyrolysis process of corn stalks is mainly composed of four stages

namely dehydration

holding

rapid weight loss

and slow weight loss.Temperature of the maximum mass loss rate is 318 ℃

325 ℃

and 341 ℃ respectively

corresponding to temperature rise rate 5 K/min

10 K/min

and 30 K/min.Based on the thermogravimetric test

three kinds of method

i.e..Coates-Redfern

maximum speed rate

and DAME

have been used to carry out dynamics calculation concerning pyrolysis of corn stalks

and the Malek method being used to screen the best mechanism equation

obtaining the kinetic model of firstorder continuous reaction at different temperature rise rate.
