In order to explore the pyrolysis properties of sesame shell and realize its effective utilization, the TG and DTG methods are adopted to investigate the pyrolysis behavior at different heating rates. The results show that the main weightlessness range is from 200 ℃ to 400 ℃, which is a fast decomposition stage, from 400 ℃ to 1000 ℃, the reaction rate slower, the weight loss decrease. Kinetic analysis show that the two pyrolysis stages can be simplified as a first-order reaction，and calculated activation energy are 23.2726.02 kJmol-1 and 19.9421.48 kJmol-1，respectively. The activation energies of low temperature pyrolysis are higher than that of high temperature pyrolysis at the same heating rate.
