Abstract�� The pyrolysis process of corn stalk and wheat straw was studied by thermo-gravimetric analysis at four different heating rates(20 ��/min,40 ��/min,60 ��/min,80 ��/min)under N_2.Experimental results showed that the pyrolysis process of corn stalk and wheat straw included three stages:pre-pyrolysis,fast pyrolysis and slow pyrolysis.With the increase of the heating rate,the maximum pyrolysis rate increased,the activation energy and pre-exponential factor increased too,the correlation coefficient of linear curve was reduced.
